PutFunctionEventInvokeConfig - Amazon Lambda
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

PutFunctionEventInvokeConfig

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, S3 bucket, 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.

Note

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

Request Syntax

PUT /2019-09-25/functions/FunctionName/event-invoke-config?Qualifier=Qualifier HTTP/1.1 Content-type: application/json { "DestinationConfig": { "OnFailure": { "Destination": "string" }, "OnSuccess": { "Destination": "string" } }, "MaximumEventAgeInSeconds": number, "MaximumRetryAttempts": number }

URI Request Parameters

The request uses the following URI parameters.

FunctionName

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.

Length Constraints: Minimum length of 1. Maximum length of 140.

Pattern: (arn:(aws[a-zA-Z-]*)?:lambda:)?([a-z]{2}(-gov)?-[a-z]+-\d{1}:)?(\d{12}:)?(function:)?([a-zA-Z0-9-_]+)(:(\$LATEST|[a-zA-Z0-9-_]+))?

Required: Yes

Qualifier

A version number or alias name.

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: (|[a-zA-Z0-9$_-]+)

Request Body

The request accepts the following data in JSON format.

DestinationConfig

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.

Type: DestinationConfig object

Required: No

MaximumEventAgeInSeconds

The maximum age of a request that Lambda sends to a function for processing.

Type: Integer

Valid Range: Minimum value of 60. Maximum value of 21600.

Required: No

MaximumRetryAttempts

The maximum number of times to retry when the function returns an error.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 2.

Required: No

Response Syntax

HTTP/1.1 200 Content-type: application/json { "DestinationConfig": { "OnFailure": { "Destination": "string" }, "OnSuccess": { "Destination": "string" } }, "FunctionArn": "string", "LastModified": number, "MaximumEventAgeInSeconds": number, "MaximumRetryAttempts": number }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

DestinationConfig

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.

Type: DestinationConfig object

FunctionArn

The Amazon Resource Name (ARN) of the function.

Type: String

Pattern: arn:(aws[a-zA-Z-]*)?:lambda:[a-z]{2}(-gov)?-[a-z]+-\d{1}:\d{12}:function:[a-zA-Z0-9-_]+(:(\$LATEST|[a-zA-Z0-9-_]+))?

LastModified

The date and time that the configuration was last updated, in Unix time seconds.

Type: Timestamp

MaximumEventAgeInSeconds

The maximum age of a request that Lambda sends to a function for processing.

Type: Integer

Valid Range: Minimum value of 60. Maximum value of 21600.

MaximumRetryAttempts

The maximum number of times to retry when the function returns an error.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 2.
