When switching a WhatsApp registered account or number from another provider to HelloSend, Two-Factor Authentication (2FA) may already be enabled, which can lead to an error when sending messages:
"Failed to send message. The account does not exist in the Cloud API. Use the /register API to create an account first."
To resolve this:
- • Follow the step-by-step guide below to disable 2FA in your Facebook Business account.
- • After disabling 2FA, go to the WhatsApp section in HelloSend, revoke the previous connection, and then reconnect your WhatsApp account with HelloSend.
