# ListGroups


 Returns group information for the specified directory. 

 This operation supports pagination with the use of the `NextToken` request and response parameters. If more results are available, the `ListGroups.NextToken` member contains a token that you pass in the next call to `ListGroups`. This retrieves the next set of items. 

 You can also specify a maximum number of return results with the `MaxResults` parameter. 

## Request Syntax
