// Merges two users having different IdentityId s, existing in the same identity
// pool, and identified by the same developer provider. You can use this action to
// request that discrete users be merged and identified as a single user in the
// Cognito environment. Cognito associates the given source user (
// SourceUserIdentifier ) with the IdentityId of the DestinationUserIdentifier .
// Only developer-authenticated users can be merged. If the users to be merged are
// associated with the same public provider, but as two different users, an
// exception will be thrown. The number of linked logins is limited to 20. So, the
// number of linked logins for the source user, SourceUserIdentifier , and the
// destination user, DestinationUserIdentifier , together should not be larger than
// 20. Otherwise, an exception will be thrown. You must use AWS Developer
// credentials to call this API.
