- 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

values take precedence over groups with higher or nullPrecedence
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 thecognito:roles
andcognito: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 samePrecedence
have the same role ARN, that role is used in thecognito:preferred_role
claim in tokens for users in each group. If the two groups have different role ARNs, thecognito:preferred_role
claim isn't set in users' tokens.The default
Precedence
value is null. The maximumPrecedence
