Response Structure

(dict) –
- Groups (list) –
  
  The group objects for the groups.
  - (dict) –
    
    The group type.
    - GroupName (string) –
      
      The name of the group.
    - UserPoolId (string) –
      
      The user pool ID for the user pool.
    - Description (string) –
      
      A string containing the description of the group.
    - RoleArn (string) –
      
      The role Amazon Resource Name (ARN) for the group.
    - Precedence (integer) –
      
      A non-negative integer value that specifies the precedence of this group relative to the other groups that a user can belong to in the user pool. Zero is the highest precedence value. Groups with lower Precedence values take precedence over groups with higher ornull Precedence values. If a user belongs to two or more groups, it is the group with the lowest precedence value whose role ARN is given in the user’s tokens for the cognito:roles and cognito:preferred_role claims.
      
      Two groups can have the same Precedence value. If this happens, neither group takes precedence over the other. If two groups with the same Precedence have the same role ARN, that role is used in the cognito:preferred_role claim in tokens for users in each group. If the two groups have different role ARNs, the cognito:preferred_role claim isn’t set in users’ tokens.
      
      The default Precedence value is null.
    - LastModifiedDate (datetime) –
      
      The date and time when the item was modified. Amazon Cognito returns this timestamp in UNIX epoch time format. Your SDK might render the output in a human-readable format like ISO 8601 or a Java Date object.
    - CreationDate (datetime) –
      
      The date and time when the item was created. Amazon Cognito returns this timestamp in UNIX epoch time format. Your SDK might render the output in a human-readable format like ISO 8601 or a Java Date object.
- NextToken (string) –
  
  An identifier that was returned from the previous call to this operation, which can be used to return the next set of items in the list.
