Troubleshooting Meta Connection Errors

If Meta API connection fails in WWA settings, check common error codes:

• Error 190 (Invalid OAuth Token): Token is expired or revoked. Regenerate your System User Token in Meta Business Settings.
• Error 100 (Param Phone Number ID invalid): Ensure you copied the Phone Number ID, not your display phone number.
• Error 200 (Permission Denied): Ensure system user has whatsapp_business_messaging scope assigned.
