Make WhatsApp error 133010 "Account not registered": register the sender

Description and use

Error 133010 in Make occurs when the phone number is known to Meta but not registered for the WhatsApp Cloud API. Fix: add a Register a Sender module, use the same number and PIN, run it once, delete the module, and retry the scenario.

Problem

A Make scenario fails with error 133010 "Account not registered" because the phone number is known to Meta but not registered for the WhatsApp Cloud API.

Outcome

Registering the sender once resolves the 133010 error; the scenario can then send messages normally.

Workflow

• Add a "WhatsApp Business Cloud › Register a Sender" module to the scenario.
• Select the same Connection and Sender ID (phone number) used by the failing module.
• Enter a 6‑digit PIN – use the existing two‑step verification PIN if enabled, otherwise the entered PIN becomes the new PIN.
• Run the Register a Sender module only once (Run this module only).
• When it succeeds, delete the Register a Sender module and re‑run the original scenario.

Evidence

[400] [133010] (#133010) Account not registered means the phone number is known to Meta but has not been registered for the WhatsApp Cloud API, so it can't send yet.

Add WhatsApp Business Cloud › Register a Sender, pick the same connection and phone number, enter a 6‑digit PIN, run it once, then delete the module and retry.

Source

Meta limits registration to 10 requests per business number in a 72‑hour moving window; after that it returns error 133016 and blocks registration of that number for the next 72 hours.
