Network.AWS.Lambda.ListEventSourceMappings

Returns a list of event source mappings you created using the CreateEventSourceMapping (see CreateEventSourceMapping), where you identify a stream as an event source. This list does not include Amazon S3 event sources.

For each mapping, the API returns configuration information. You can optionally specify filters to retrieve specific event source mappings.

This operation requires permission for the 'lambda:ListEventSourceMappings' action.

See: AWS API Reference for ListEventSourceMappings.

This operation returns paginated results.

Creating a Request

listEventSourceMappings :: ListEventSourceMappings

Creates a value of ListEventSourceMappings with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• lesmEventSourceARN
• lesmMaxItems
• lesmMarker
• lesmFunctionName

data ListEventSourceMappings

See: listEventSourceMappings smart constructor.

Request Lenses

lesmEventSourceARN :: Lens' ListEventSourceMappings (Maybe Text)

The Amazon Resource Name (ARN) of the Amazon Kinesis stream.

lesmMaxItems :: Lens' ListEventSourceMappings (Maybe Natural)

Optional integer. Specifies the maximum number of event sources to return in response. This value must be greater than 0.

lesmMarker :: Lens' ListEventSourceMappings (Maybe Text)

Optional string. An opaque pagination token returned from a previous ListEventSourceMappings operation. If present, specifies to continue the list from where the returning call left off.

lesmFunctionName :: Lens' ListEventSourceMappings (Maybe Text)

The name of the Lambda function.

You can specify an unqualified function name (for example, "Thumbnail") or you can specify Amazon Resource Name (ARN) of the function (for example, "arn:aws:lambda:us-west-2:account-id:function:ThumbNail"). AWS Lambda also allows you to specify only the account ID qualifier (for example, "account-id:Thumbnail"). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 character in length.

Destructuring the Response
