Remove your sender domain
Partner key only. Removes the domain; email goes from LettBestilt’s domain again. Does not need white label, so a domain can be cleaned up afterwards. A new domain gets a new DKIM value. Needs a key created by an owner or administrator. LettBestilt MCP never removes the sender domain.
Authentication
The partner key (lbp_test_… or lbp_live_…), sent as Authorization: Bearer lbp_… and created in LettBestilt Partner under Partner key. It belongs to the whole partner, not to a restaurant, and only works against /api/v1/partner. Server to server only: a request with an Origin header is rejected with 403 FORBIDDEN, and the key must never be in a browser. A TEST key sees and creates only sandboxes; LIVE keys work once LettBestilt Partner is open. A suspended or archived partner, a revoked key and a restaurant key (lbs_…) here give 401 UNAUTHORIZED; an expired key gives 401 KEY_EXPIRED.
Response
The sender domain after the removal (empty).
