ListEventSourceMappings - AWS Lambda (original) (raw)

Lists event source mappings. Specify an EventSourceArn to show only event source mappings for a single event source.

Request Syntax

GET /2015-03-31/event-source-mappings/?EventSourceArn=EventSourceArn&FunctionName=FunctionName&Marker=Marker&MaxItems=MaxItems HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

EventSourceArn

The Amazon Resource Name (ARN) of the event source.

Amazon Kinesis – The ARN of the data stream or a stream consumer.
Amazon DynamoDB Streams – The ARN of the stream.
Amazon Simple Queue Service – The ARN of the queue.
Amazon Managed Streaming for Apache Kafka – The ARN of the cluster or the ARN of the VPC connection (for cross-account event source mappings).
Amazon MQ – The ARN of the broker.
Amazon DocumentDB – The ARN of the DocumentDB change stream.

Pattern: arn:(aws[a-zA-Z0-9-]*):([a-zA-Z0-9\-])+:([a-z]{2}(-gov)?-[a-z]+-\d{1})?:(\d{12})?:(.*)

FunctionName

The name or ARN of the Lambda function.

Name formats

Function name – MyFunction.
Function ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction.
Version or Alias ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD.
Partial ARN – 123456789012:function:MyFunction.

The length constraint applies only to the full ARN. If you specify only the function name, it's 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-_]+))?

Marker

A pagination token returned by a previous call.

MaxItems

The maximum number of event source mappings to return. Note that ListEventSourceMappings returns a maximum of 100 items in each response, even if you set the number higher.

Valid Range: Minimum value of 1. Maximum value of 10000.

Request Body

The request does not have a request body.
