This was a couple months ago.on a whatsapp agent i was building for a "client". n8n sends the message through the cloud api, the api answers with a message id, everything looks fine. but nobody was receiving anything i spent a whole evening on the wrong problem. i thought it was my token, because session tokens die after an hour or two, so i swapped it for a 60 day one. still nothing what finally showed it was the status webhook. every message came back failed with error 131031, "business account has been locked". meta had locked the whole business portfolio. the whatsapp account itself still showed active and approved, so from the dashboard you can't see it no code fixes that. you appeal through meta's security center and wait. we didn't wait, we moved the number to twilio as the provider and it worked the same day since then every whatsapp workflow i build has a status callback that pings me on telegram when a message fails. the send request alone tells you nothing has meta locked one of your accounts before? how long did the appeal take?
