WhatsApp Blocked Users

List blocked users

Lists blocked users for the specified WhatsApp business phone number. You must have management permissions for this business phone number.

Results come from Meta’s blocklist. Users do not need to exist in YCloud Contacts to appear in the results. The response includes the available phone and user IDs; it does not include contact details or block timestamps.

Use cursor pagination. Omit the cursors for the first request, then pass cursor.after as pageAfter to request the next page, or cursor.before as pageBefore to request the previous page.
