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.

LastEvaluatedStreamArn

The stream ARN of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedStreamArn is empty, then the "last page" of results has been processed and there is no more data to be retrieved.

If LastEvaluatedStreamArn is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedStreamArn is empty.

Type: String

Length Constraints: Minimum length of 37. Maximum length of 1024.

Streams

A list of stream descriptors associated with the current account and endpoint.

Type: Array of Stream objects
