A low-level client representing AWS Lambda
Overview
Lambda is a compute service that lets you run code without provisioning or managing servers. Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. With Lambda, you can run code for virtually any type of application or backend service. For more information about the Lambda service, see What is Lambda in the Lambda Developer Guide .
The Lambda API Reference provides information about each of the API methods, including details about the parameters in each API request and response.
You can use Software Development Kits (SDKs), Integrated Development Environment (IDE) Toolkits, and command line tools to access the API. For installation instructions, see Tools for Amazon Web Services .
For a list of Region-specific endpoints that Lambda supports, see Lambda endpoints and quotas in the Amazon Web Services General Reference. .
When making the API calls, you will need to authenticate your request by providing a signature. Lambda supports signature version 4. For more information, see Signature Version 4 signing process in the Amazon Web Services General Reference. .
CA certificates
Because Amazon Web Services SDKs use the CA certificates from your computer, changes to the certificates on the Amazon Web Services servers can cause connection failures when you attempt to use an SDK. You can prevent these failures by keeping your computer's CA certificates and operating system up-to-date. If you encounter this issue in a corporate environment and do not manage your own computer, you might need to ask an administrator to assist with the update process. The following list shows minimum operating system and Java versions:
When accessing the Lambda management console or Lambda API endpoints, whether through browsers or programmatically, you will need to ensure your client machines support any of the following CAs:
Root certificates from the first two authorities are available from Amazon trust services , but keeping your computer up-to-date is the more straightforward solution. To learn more about ACM-provided certificates, see Amazon Web Services Certificate Manager FAQs.

These are the available methods:
Adds permissions to the resource-based policy of a version of an Lambda layer . Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.
To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.

Grants an Amazon Web Services service, account, or organization permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. Note: Lambda does not support adding policies to version $LATEST.
To grant permission to another account, specify the account ID as the Principal . To grant permission to an organization defined in Organizations, specify the organization ID as the PrincipalOrgID . For Amazon Web Services services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com . For Amazon Web Services services, you can also specify the ARN of the associated resource as the SourceArn . If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.
This action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies .

Creates a Lambda function. To create a function, you need a deployment package and an execution role . The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.
You set the package type to Image if the deployment package is a container image . For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.
You set the package type to Zip if the deployment package is a .zip file archive . For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64 ). If you do not specify the architecture, the default value is x86-64 .
When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State , StateReason , and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Function States .
A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.
The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration . Function-level settings apply to both the unpublished and published versions of the function, and include tags ( TagResource ) and per-function concurrency limits ( PutFunctionConcurrency ).
You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode , Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set set of signing profiles, which define the trusted publishers for this function.
If another account or an Amazon Web Services service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.
To invoke your function directly, use Invoke . To invoke your function in response to events in other Amazon Web Services services, create an event source mapping ( CreateEventSourceMapping ), or configure a function trigger in the other service. For more information, see Invoking Functions .

Response Structure
A mapping between an Amazon Web Services resource and a Lambda function. For details, see CreateEventSourceMapping .
The identifier of the event source mapping.
The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.
With StartingPosition set to AT_TIMESTAMP , the time from which to start reading.
The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).
Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.
Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.
(Streams and Amazon SQS standard queues) The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function.
Default: 0
Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.
(Streams only) The number of batches to process concurrently from each shard. The default value is 1.
The Amazon Resource Name (ARN) of the event source.
(Streams and Amazon SQS) An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering .
A list of filters.
A structure within a FilterCriteria object that defines an event filtering pattern.
A filter pattern. For more information on the syntax of a filter pattern, see Filter rule syntax .
The ARN of the Lambda function.
The date that the event source mapping was last updated or that its state changed.
The result of the last Lambda invocation of your function.
The state of the event source mapping. It can be one of the following: Creating , Enabling , Enabled , Disabling , Disabled , Updating , or Deleting .
Indicates whether a user or Lambda made the last change to the event source mapping.
(Streams only) An Amazon SQS queue or Amazon SNS topic destination for discarded records.
The destination configuration for successful invocations.
The Amazon Resource Name (ARN) of the destination resource.
The destination configuration for failed invocations.
The Amazon Resource Name (ARN) of the destination resource.
The name of the Kafka topic.
(Amazon MQ) The name of the Amazon MQ broker destination queue to consume.
An array of the authentication protocol, VPC components, or virtual host to secure and define your event source.
To secure and define access to your event source, you can specify the authentication protocol, VPC components, or virtual host.
The type of authentication protocol, VPC components, or virtual host for your event source. For example: "Type":"SASL_SCRAM_512_AUTH" .
The value for your chosen configuration in Type . For example: "URI": "arn:aws:secretsmanager:us-east-1:01234567890:secret:MyBrokerSecretName" .
The self-managed Apache Kafka cluster for your event source.
The list of bootstrap servers for your Kafka brokers in the following format: "KAFKA_BOOTSTRAP_SERVERS": ["abc.xyz.com:xxxx","abc2.xyz.com:xxxx"] .
(Streams only) Discard records older than the specified age. The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.
(Streams only) If the function returns an error, split the batch in two and retry. The default value is false.
(Streams only) Discard records after the specified number of retries. The default value is -1, which sets the maximum number of retries to infinite. When MaximumRetryAttempts is infinite, Lambda retries failed records until the record expires in the event source.
(Streams only) The duration in seconds of a processing window. The range is 1–900 seconds.
(Streams only) A list of current response type enums applied to the event source mapping.

Returns an object that can wait for some condition.
Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event .
For synchronous invocation , details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace .
When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior .
For asynchronous invocation , Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue .
The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors , or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if executing the function would cause you to exceed a concurrency limit at either the account level (ConcurrentInvocationLimitExceeded ) or function level (ReservedFunctionConcurrentInvocationLimitExceeded ).
For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.
This operation requires permission for the lambda:InvokeFunction action.

Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.
Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.
Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit.

Configures options for asynchronous invocation on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig .
By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration .
To send an invocation record to a queue, topic, function, or event bus, specify a destination . You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

Modify the version-specific settings of a Lambda function.
When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus , LastUpdateStatusReason , and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Function States .
These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.
To configure function concurrency, use PutFunctionConcurrency . To grant invoke permissions to an account or Amazon Web Services service, use AddPermission .
