SyntaxPropertiesReturn values

AWS::Cognito::UserPoolGroup

A user pool group. Contains details about the group and the way that it contributes to IAM role decisions with identity pools. Identity pools can make decisions about the IAM role to assign based on groups: users get credentials for the role associated with their highest-priority group.

This data type is a response parameter of AdminListGroupsForUser, CreateGroup, GetGroup, ListGroups, and UpdateGroup.

Precedence

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 or null 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. The maximum Precedence value is 2^31-1.

Required: No

Type: Integer

Minimum: 0

Update requires: No interruption
