Answer 1

Hi @Thomas Pichler Aftersales

It is not possible to delete another user's contacts in a delegated context, this is only available in application context.

You should grant the Contacts.ReadWrite application permission to the calling app, then use daemon-based client credentials flow to request an access token and call that API endpoint in Postman.

Hope this helps.
