This operation requires permission for the lambda:DeleteEventSourceMapping action.

Request Syntax

Copy
DELETE /2015-03-31/event-source-mappings/UUID HTTP/1.1

URI Request Parameters

The request requires the following URI parameters.

UUID

The event source mapping ID.

Request Body

The request does not have a request body.

Response Syntax

Copy
HTTP/1.1 202
Content-type: application/json

   "BatchSize": number,
   "EventSourceArn": "string",
   "FunctionArn": "string",
   "LastModified": number,
   "LastProcessingResult": "string",
   "State": "string",
   "StateTransitionReason": "string",

}

Response Elements

If the action is successful, the service sends back an HTTP 202 response.

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

BatchSize

The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. Your function receives an event with all the retrieved records.

Type: Integer

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

EventSourceArn

The Amazon Resource Name (ARN) of the Amazon Kinesis stream that is the source of events.

Type: String

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

FunctionArn

The Lambda function to invoke when AWS Lambda detects an event on the stream.

Type: String

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

LastModified

The UTC time string indicating the last time the event mapping was updated.

Type: Timestamp

LastProcessingResult

The result of the last AWS Lambda invocation of your Lambda function.

Type: String

State

The state of the event source mapping. It can be Creating, Enabled, Disabled, Enabling, Disabling, Updating, or Deleting.

Type: String

StateTransitionReason

The reason the event source mapping is in its current state. It is either user-requested or an AWS Lambda-initiated state transition.

Type: String

UUID

The AWS Lambda assigned opaque identifier for the mapping.

Type: String

Errors

InvalidParameterValueException

One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception. You will also get this exception if you have selected a deprecated runtime, such as Node v0.10.42.

HTTP Status Code: 400

The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
