ListGroupResources - AWS Resource Groups


Returns a list of ARNs of resources that are members of a specified resource group.

Request Syntax

POST /groups/GroupName/resource-identifiers-list?maxResults=MaxResults&nextToken=NextToken HTTP/1.1 Content-type: application/json { "Filters": [ { "Name": "string", "Values": [ "string" ] } ] }

URI Request Parameters

The request uses the following URI parameters.


The name of the resource group.

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [a-zA-Z0-9_\.-]+

Required: Yes


The maximum number of group member ARNs that are returned in a single call by ListGroupResources, in paginated output. By default, this number is 50.

Valid Range: Minimum value of 1. Maximum value of 50.


The NextToken value that is returned in a paginated ListGroupResources request. To get the next page of results, run the call again, add the NextToken parameter, and specify the NextToken value.

Request Body

The request accepts the following data in JSON format.


Filters, formatted as ResourceFilter objects, that you want to apply to a ListGroupResources operation.

  • resource-type - Filter resources by their type. Specify up to five resource types in the format AWS::ServiceCode::ResourceType. For example, AWS::EC2::Instance, or AWS::S3::Bucket.

When you specify a resource-type filter for ListGroupResources, AWS Resource Groups validates your filter resource types against the types that are defined in the query associated with the group. For example, if a group contains only S3 buckets because its query specifies only that resource type, but your resource-type filter includes EC2 instances, AWS Resource Groups does not filter for EC2 instances. In this case, a ListGroupResources request returns a BadRequestException error with a message similar to the following:

The resource types specified as filters in the request are not valid.

The error includes a list of resource types that failed the validation because they are not part of the query associated with the group. This validation doesn't occur when the group query specifies AWS::AllSupported, because a group based on such a query can contain any of the allowed resource types for the query type (tag-based or AWS CloudFormation stack-based queries).

Type: Array of ResourceFilter objects

Required: No
