update_function_event_invoke_config

Lambda.Client.update_function_event_invoke_config(**kwargs)

Updates the configuration for asynchronous invocation for a function, version, or alias.

To configure options for asynchronous invocation, use PutFunctionEventInvokeConfig.

Request Syntax

response = client.update_function_event_invoke_config(
    FunctionName='string',
    Qualifier='string',
    MaximumRetryAttempts=123,
    MaximumEventAgeInSeconds=123,
    DestinationConfig={
        'OnSuccess': {
            'Destination': 'string'
        },
        'OnFailure': {
            'Destination': 'string'
        }
    }
)

Parameters:

• FunctionName (string) –

  [REQUIRED]

  The name or ARN of the Lambda function, version, or alias.

  Name formats

  • Function name - my-function (name-only), my-function:v1 (with alias).

  • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function.

  • Partial ARN - 123456789012:function:my-function.

  You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

• Qualifier (string) – A version number or alias name.

• MaximumRetryAttempts (integer) – The maximum number of times to retry when the function returns an error.

• MaximumEventAgeInSeconds (integer) – The maximum age of a request that Lambda sends to a function for processing.

• DestinationConfig (dict) –

  A destination for events after they have been sent to a function for processing.

  Destinations

  • Function - The Amazon Resource Name (ARN) of a Lambda function.

  • Queue - The ARN of a standard SQS queue.

  • Bucket - The ARN of an Amazon S3 bucket.

  • Topic - The ARN of a standard SNS topic.

  • Event Bus - The ARN of an Amazon EventBridge event bus.

  Note

  S3 buckets are supported only for on-failure destinations. To retain records of successful invocations, use another destination type.

  • OnSuccess (dict) –

    The destination configuration for successful invocations.

    • Destination (string) –

      The Amazon Resource Name (ARN) of the destination resource.

  • OnFailure (dict) –

    The destination configuration for failed invocations.

    • Destination (string) –

      The Amazon Resource Name (ARN) of the destination resource.

      To retain records of unsuccessful asynchronous invocations, you can configure an Amazon SNS topic, Amazon SQS queue, Amazon S3 bucket, Lambda function, or Amazon EventBridge event bus as the destination.

      To retain records of failed invocations from Kinesis, DynamoDB, self-managed Kafka or Amazon MSK, you can configure an Amazon SNS topic, Amazon SQS queue, or Amazon S3 bucket as the destination.

Return type:

dict

Returns:

Examples

The following example adds an on-failure destination to the existing asynchronous invocation configuration for a function named my-function.

response = client.update_function_event_invoke_config(
    DestinationConfig={
        'OnFailure': {
            'Destination': 'arn:aws:sqs:us-east-2:123456789012:destination',
        },
    },
    FunctionName='my-function',
)

print(response)

Expected Output:

        },
        'OnSuccess': {
        },
    },
