A low-level client representing Amazon EventBridge:
import boto3
client = boto3.client('events')
These are the available methods:
Activates a partner event source that has been deactivated. Once activated, your matching event bus will start receiving events from the event source.
See also: AWS API Documentation
Request Syntax
response = client.activate_event_source(
Name='string'
)
[REQUIRED]
The name of the partner event source to activate.
Exceptions
Check if an operation can be paginated.
Creates a new event bus within your account. This can be a custom event bus which you can use to receive events from your custom applications and services, or it can be a partner event bus which can be matched to a partner event source.
See also: AWS API Documentation
Request Syntax
response = client.create_event_bus(
Name='string',
EventSourceName='string',
Tags=[
{
'Key': 'string',
'Value': 'string'
},
]
)
[REQUIRED]
The name of the new event bus.
Event bus names cannot contain the / character. You can't use the name default for a custom event bus, as this name is already used for your account's default event bus.
If this is a partner event bus, the name must exactly match the name of the partner event source that this event bus is matched to.
Tags to associate with the event bus.
A key-value pair associated with an AWS resource. In EventBridge, rules and event buses support tagging.
A string you can use to assign a value. The combination of tag keys and values can help you organize and categorize your resources.
The value for the specified tag key.

Called by an SaaS partner to create a partner event source. This operation is not used by AWS customers.
Each partner event source can be used by one AWS account to create a matching partner event bus in that AWS account. A SaaS partner must create one partner event source for each AWS account that wants to receive those event types.
A partner event source creates events based on resources within the SaaS partner's service or application.
An AWS account that creates a partner event bus that matches the partner event source can use that event bus to receive events from the partner, and then process them using AWS Events rules and targets.
Partner event source names follow this format:
`` partner_name /event_namespace /event_name ``
partner_name is determined during partner registration and identifies the partner to AWS customers. event_namespace is determined by the partner and is a way for the partner to categorize their events. event_name is determined by the partner, and should uniquely identify an event-generating resource within the partner system. The combination of event_namespace and event_name should help AWS customers decide whether to create an event bus to receive these events.

Request Syntax
response = client.create_partner_event_source(
Name='string',
Account='string'
)
[REQUIRED]
The name of the partner event source. This name must be unique and must be in the format `` partner_name /event_namespace /event_name `` . The AWS account that wants to use this partner event source must create a partner event bus with a name that matches the name of the partner event source.

Targets are the resources to be invoked when a rule is triggered. For a complete list of services and resources that can be set as a target, see PutTargets .
If you are setting the event bus of another account as the target, and that account granted permission to your account through an organization instead of directly by the account ID, then you must specify a RoleArn with proper permissions in the Target structure. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide .
Id (string) --
The ID of the target.
Arn (string) --
The Amazon Resource Name (ARN) of the target.
RoleArn (string) --
The Amazon Resource Name (ARN) of the IAM role to be used for this target when the rule is triggered. If one rule triggers multiple targets, you can use a different IAM role for each target.

Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format .
InputPath (string) --
The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath .
InputTransformer (dict) --
Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.
InputPathsMap (dict) --
Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.
InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.
The keys cannot start with "AWS."
InputTemplate (string) --
Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value > The InputTemplate must be valid JSON.
If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:
The following example shows the syntax for using InputPathsMap and InputTemplate .
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state <status>"
}
To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state \"<status>\""
}

The FARGATE value is supported only in the Regions where AWS Fargate with Amazon ECS is supported. For more information, see AWS Fargate on Amazon ECS in the Amazon Elastic Container Service Developer Guide .
NetworkConfiguration (dict) --
Use this structure if the ECS task uses the awsvpc network mode. This structure specifies the VPC subnets and security groups associated with the task, and whether a public IP address is to be used. This structure is required if LaunchType is FARGATE because the awsvpc mode is required for Fargate tasks.
If you specify NetworkConfiguration when the target ECS task does not use the awsvpc network mode, the task fails.

ArrayProperties (dict) --
The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.
Size (integer) --
The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.
RetryStrategy (dict) --
The retry strategy to use for failed jobs, if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1–10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.

Running PutPermission permits the specified AWS account or AWS organization to put events to the specified event bus . CloudWatch Events rules in your account are triggered by these events arriving to an event bus in your account.
For another account to send events to your account, that external account must have an EventBridge rule with your account's event bus as a target.
To enable multiple AWS accounts to put events to your event bus, run PutPermission once for each of these accounts. Or, if all the accounts are members of the same AWS organization, you can run PutPermission once specifying Principal as "*" and specifying the AWS organization ID in Condition , to grant permissions to all accounts in that organization.
If you grant permissions using an organization, then accounts in that organization must specify a RoleArn with proper permissions when they use PutTarget to add your account's event bus as a target. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide .
The permission policy on the default event bus cannot exceed 10 KB in size.

The 12-digit AWS account ID that you are permitting to put events to your default event bus. Specify "*" to permit any account to put events to your default event bus.
If you specify "*" without specifying Condition , avoid creating rules that may match undesirable events. To create more secure rules, make sure that the event pattern for each rule contains an account field with a specific account ID from which to receive events. Rules with an account field do not match any events sent from other accounts.
[REQUIRED]
An identifier string for the external account that you are granting permissions to. If you later want to revoke the permission for this external account, specify this StatementId when you run RemovePermission .
This parameter enables you to limit the permission to accounts that fulfill a certain condition, such as being a member of a certain AWS organization. For more information about AWS Organizations, see What Is AWS Organizations in the AWS Organizations User Guide .
If you specify Condition with an AWS organization ID, and specify "*" as the value for Principal , you grant permission to all the accounts in the named organization.
The Condition is a JSON string which must contain Type , Key , and Value fields.
Specifies the type of condition. Currently the only supported value is StringEquals .
Specifies the key for the condition. Currently the only supported key is aws:PrincipalOrgID .
Specifies the value for the key. Currently, this must be the ID of the organization.

Exceptions
Creates or updates the specified rule. Rules are enabled by default, or based on value of the state. You can disable a rule using DisableRule .
A single rule watches for events from a single event bus. Events generated by AWS services go to your account's default event bus. Events generated by SaaS partner services or applications go to the matching partner event bus. If you have custom applications or services, you can specify whether their events go to your default event bus or a custom event bus that you have created. For more information, see CreateEventBus .
If you are updating an existing rule, the rule is replaced with what you specify in this PutRule command. If you omit arguments in PutRule , the old values for those arguments are not kept. Instead, they are replaced with null values.
When you create or update a rule, incoming events might not immediately start matching to new or updated rules. Allow a short period of time for changes to take effect.
A rule must contain at least an EventPattern or ScheduleExpression. Rules with EventPatterns are triggered when a matching event is observed. Rules with ScheduleExpressions self-trigger based on the given schedule. A rule can have both an EventPattern and a ScheduleExpression, in which case the rule triggers on matching events as well as on a schedule.
When you initially create a rule, you can optionally assign one or more tags to the rule. Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only rules with certain tag values. To use the PutRule operation and assign tags, you must have both the events:PutRule and events:TagResource permissions.
If you are updating an existing rule, any tags you specify in the PutRule operation are ignored. To update the tags of an existing rule, use TagResource and UntagResource .
Most services in AWS treat : or / as the same character in Amazon Resource Names (ARNs). However, EventBridge uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event you want to match.
In EventBridge, it is possible to create rules that lead to infinite loops, where a rule is fired repeatedly. For example, a rule might detect that ACLs have changed on an S3 bucket, and trigger software to change them to the desired state. If the rule is not written carefully, the subsequent change to the ACLs fires the rule again, creating an infinite loop.
To prevent this, write the rules so that the triggered actions do not re-fire the same rule. For example, your rule could fire only if ACLs are found to be in a bad state, instead of after any change.
An infinite loop can quickly cause higher than expected charges. We recommend that you use budgeting, which alerts you when charges exceed your specified limit. For more information, see Managing Your Costs with Budgets .

Exceptions
Adds the specified targets to the specified rule, or updates the targets if they are already associated with the rule.
Targets are the resources that are invoked when a rule is triggered.
You can configure the following as targets for Events:
Creating rules with built-in targets is supported only in the AWS Management Console. The built-in targets are EC2 CreateSnapshot API call , EC2 RebootInstances API call , EC2 StopInstances API call , and EC2 TerminateInstances API call .
For some target types, PutTargets provides target-specific parameters. If the target is a Kinesis data stream, you can optionally specify which shard the event goes to by using the KinesisParameters argument. To invoke a command on multiple EC2 instances with one rule, you can use the RunCommandParameters field.
To be able to make API calls against the resources that you own, Amazon CloudWatch Events needs the appropriate permissions. For AWS Lambda and Amazon SNS resources, EventBridge relies on resource-based policies. For EC2 instances, Kinesis data streams, and AWS Step Functions state machines, EventBridge relies on IAM roles that you specify in the RoleARN argument in PutTargets . For more information, see Authentication and Access Control in the Amazon EventBridge User Guide .
If another AWS account is in the same region and has granted you permission (using PutPermission ), you can send events to that account. Set that account's event bus as a target of the rules in your account. To send the matched events to the other account, specify that account's event bus as the Arn value when you run PutTargets . If your account sends events to another account, your account is charged for each sent event. Each event sent to another account is charged as a custom event. The account receiving the event is not charged. For more information, see Amazon CloudWatch Pricing .
Note
Input , InputPath , and InputTransformer are not available with PutTarget if the target is an event bus of a different AWS account.
If you are setting the event bus of another account as the target, and that account granted permission to your account through an organization instead of directly by the account ID, then you must specify a RoleArn with proper permissions in the Target structure. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide .
For more information about enabling cross-account events, see PutPermission .
Input , InputPath , and InputTransformer are mutually exclusive and optional parameters of a target. When a rule is triggered due to a matched event:
When you specify InputPath or InputTransformer , you must use JSON dot notation, not bracket notation.
When you add targets to a rule and the associated rule triggers soon after, new or updated targets might not be immediately invoked. Allow a short period of time for changes to take effect.
This action can partially fail if too many requests are made at the same time. If that happens, FailedEntryCount is non-zero in the response and each entry in FailedEntries provides the ID of the failed target and the error code.

[REQUIRED]
The name of the rule.
[REQUIRED]
The targets to update or add to the rule.
Targets are the resources to be invoked when a rule is triggered. For a complete list of services and resources that can be set as a target, see PutTargets .
If you are setting the event bus of another account as the target, and that account granted permission to your account through an organization instead of directly by the account ID, then you must specify a RoleArn with proper permissions in the Target structure. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide .
The ID of the target.
The Amazon Resource Name (ARN) of the target.
The Amazon Resource Name (ARN) of the IAM role to be used for this target when the rule is triggered. If one rule triggers multiple targets, you can use a different IAM role for each target.
Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format .
The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath .
Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.
Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.
InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.
The keys cannot start with "AWS."
Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value > The InputTemplate must be valid JSON.
If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:
The following example shows the syntax for using InputPathsMap and InputTemplate .
"InputTransformer":{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state <status>"
}
To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:
"InputTransformer":{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state \"<status>\""
}
The custom parameter you can use to control the shard assignment, when the target is a Kinesis data stream. If you do not include this parameter, the default is to use the eventId as the partition key.
The JSON path to be extracted from the event and used as the partition key. For more information, see Amazon Kinesis Streams Key Concepts in the Amazon Kinesis Streams Developer Guide .
Parameters used when you are using the rule to invoke Amazon EC2 Run Command.
Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.
Information about the EC2 instances that are to be sent the command, specified as key-value pairs. Each RunCommandTarget block can include only one key, but this key may specify multiple values.
Can be either tag: tag-key or InstanceIds .
If Key is tag: tag-key , Values is a list of tag values. If Key is InstanceIds , Values is a list of Amazon EC2 instance IDs.
Contains the Amazon ECS task definition and task count to be used, if the event target is an Amazon ECS task. For more information about Amazon ECS tasks, see Task Definitions in the Amazon EC2 Container Service Developer Guide .
The ARN of the task definition to use if the event target is an Amazon ECS task.
The number of tasks to create based on TaskDefinition . The default is 1.
Specifies the launch type on which your task is running. The launch type that you specify here must match one of the launch type (compatibilities) of the target task. The FARGATE value is supported only in the Regions where AWS Fargate with Amazon ECS is supported. For more information, see AWS Fargate on Amazon ECS in the Amazon Elastic Container Service Developer Guide .
Use this structure if the ECS task uses the awsvpc network mode. This structure specifies the VPC subnets and security groups associated with the task, and whether a public IP address is to be used. This structure is required if LaunchType is FARGATE because the awsvpc mode is required for Fargate tasks.
If you specify NetworkConfiguration when the target ECS task does not use the awsvpc network mode, the task fails.
Use this structure to specify the VPC subnets and security groups for the task, and whether a public IP address is to be used. This structure is relevant only for ECS tasks that use the awsvpc network mode.
Specifies the subnets associated with the task. These subnets must all be in the same VPC. You can specify as many as 16 subnets.
Specifies the security groups associated with the task. These security groups must all be in the same VPC. You can specify as many as five security groups. If you do not specify a security group, the default security group for the VPC is used.
Specifies whether the task's elastic network interface receives a public IP address. You can specify ENABLED only when LaunchType in EcsParameters is set to FARGATE .
Specifies the platform version for the task. Specify only the numeric portion of the platform version, such as 1.1.0 .
This structure is used only if LaunchType is FARGATE . For more information about valid platform versions, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
Specifies an ECS task group for the task. The maximum length is 255 characters.
If the event target is an AWS Batch job, this contains the job definition, job name, and other parameters. For more information, see Jobs in the AWS Batch User Guide .
The ARN or name of the job definition to use if the event target is an AWS Batch job. This job definition must already exist.
The name to use for this execution of the job, if the target is an AWS Batch job.
The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.
The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.
The retry strategy to use for failed jobs, if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1–10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.
The number of times to attempt to retry, if the job fails. Valid values are 1–10.
Contains the message group ID to use when the target is a FIFO queue.
If you specify an SQS FIFO queue as a target, the queue must have content-based deduplication enabled.
The FIFO message group ID to use as the target.

You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values. In EventBridge, rules and event buses can be tagged.
Tags don't have any semantic meaning to AWS and are interpreted strictly as strings of characters.
You can use the TagResource action with a resource that already has tags. If you specify a new tag key, this tag is appended to the list of tags associated with the resource. If you specify a tag key that is already associated with the resource, the new tag value that you specify replaces the previous value for that tag.

Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format .
InputPath (string) --
The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath .
InputTransformer (dict) --
Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.
InputPathsMap (dict) --
Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.
InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.
The keys cannot start with "AWS."
InputTemplate (string) --
Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value > The InputTemplate must be valid JSON.
If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:
The following example shows the syntax for using InputPathsMap and InputTemplate .
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state <status>"
}
To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state \"<status>\""
}
KinesisParameters (dict) --
The custom parameter you can use to control the shard assignment, when the target is a Kinesis data stream. If you do not include this parameter, the default is to use the eventId as the partition key.
PartitionKeyPath (string) --
The JSON path to be extracted from the event and used as the partition key. For more information, see Amazon Kinesis Streams Key Concepts in the Amazon Kinesis Streams Developer Guide .
RunCommandParameters (dict) --
Parameters used when you are using the rule to invoke Amazon EC2 Run Command.
RunCommandTargets (list) --
Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.
(dict) --
Information about the EC2 instances that are to be sent the command, specified as key-value pairs. Each RunCommandTarget block can include only one key, but this key may specify multiple values.
Key (string) --
Can be either tag: tag-key or InstanceIds .
Values (list) --
If Key is tag: tag-key , Values is a list of tag values. If Key is InstanceIds , Values is a list of Amazon EC2 instance IDs.
EcsParameters (dict) --
Contains the Amazon ECS task definition and task count to be used, if the event target is an Amazon ECS task. For more information about Amazon ECS tasks, see Task Definitions in the Amazon EC2 Container Service Developer Guide .
TaskDefinitionArn (string) --
The ARN of the task definition to use if the event target is an Amazon ECS task.
TaskCount (integer) --
The number of tasks to create based on TaskDefinition . The default is 1.
LaunchType (string) --
Specifies the launch type on which your task is running. The launch type that you specify here must match one of the launch type (compatibilities) of the target task. The FARGATE value is supported only in the Regions where AWS Fargate with Amazon ECS is supported. For more information, see AWS Fargate on Amazon ECS in the Amazon Elastic Container Service Developer Guide .
NetworkConfiguration (dict) --
Use this structure if the ECS task uses the awsvpc network mode. This structure specifies the VPC subnets and security groups associated with the task, and whether a public IP address is to be used. This structure is required if LaunchType is FARGATE because the awsvpc mode is required for Fargate tasks.
If you specify NetworkConfiguration when the target ECS task does not use the awsvpc network mode, the task fails.
awsvpcConfiguration (dict) --
Use this structure to specify the VPC subnets and security groups for the task, and whether a public IP address is to be used. This structure is relevant only for ECS tasks that use the awsvpc network mode.
Subnets (list) --
Specifies the subnets associated with the task. These subnets must all be in the same VPC. You can specify as many as 16 subnets.
SecurityGroups (list) --
Specifies the security groups associated with the task. These security groups must all be in the same VPC. You can specify as many as five security groups. If you do not specify a security group, the default security group for the VPC is used.
AssignPublicIp (string) --
Specifies whether the task's elastic network interface receives a public IP address. You can specify ENABLED only when LaunchType in EcsParameters is set to FARGATE .
PlatformVersion (string) --
Specifies the platform version for the task. Specify only the numeric portion of the platform version, such as 1.1.0 .
This structure is used only if LaunchType is FARGATE . For more information about valid platform versions, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
Group (string) --
Specifies an ECS task group for the task. The maximum length is 255 characters.
BatchParameters (dict) --
If the event target is an AWS Batch job, this contains the job definition, job name, and other parameters. For more information, see Jobs in the AWS Batch User Guide .
JobDefinition (string) --
The ARN or name of the job definition to use if the event target is an AWS Batch job. This job definition must already exist.
JobName (string) --
The name to use for this execution of the job, if the target is an AWS Batch job.
ArrayProperties (dict) --
The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.
Size (integer) --
The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.
RetryStrategy (dict) --
The retry strategy to use for failed jobs, if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1–10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.
Attempts (integer) --
The number of times to attempt to retry, if the job fails. Valid values are 1–10.
SqsParameters (dict) --
Contains the message group ID to use when the target is a FIFO queue.
If you specify an SQS FIFO queue as a target, the queue must have content-based deduplication enabled.
MessageGroupId (string) --
The FIFO message group ID to use as the target.
