Request Syntax

{ "maxResults": number, "nextToken": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


The maximum number of repository results that's returned by DescribeRegistries in paginated output. When this parameter is used, DescribeRegistries only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeRegistries request with the returned nextToken value. This value can be between 1 and 1000. If this parameter isn't used, then DescribeRegistries returns up to 100 results and a nextToken value, if applicable.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 1000.

Required: No


The nextToken value that's returned from a previous paginated DescribeRegistries request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. If there are no more results to return, this value is null.


This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

Type: String

Required: No
