AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Merges two users having different IdentityIds, 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.

You must use AWS Developer credentials to call this API.

Note:

For PCL and Unity this operation is only available in asynchronous form. Please refer to MergeDeveloperIdentitiesAsync.
