@adriana4u , There is one way is by merging SSOid to other dupe user. But you will loose one of the user data from community if you merge user to another. Another way is to edit all the messages of one of the user you want to merge and update the author of that user. and then You can have all the posts on behalf of that user. But make sure the message author must have permission to post as this user or the call will fail. The author can be specified as a relative REST API path, such as id/43 to specify the author by id or login/username to specify the author by username, or by an absolute path beginning with a forward slash, like /users/id/43 . Example API specified in this documentation: https://devdocportal.khoros.com/t5/Community-API-v1-Reference/bd-p/restv1docs?section=commv1&leaf-id=Message.edit#Message.edit
