Twilio WhatsApp bulk messaging with Ultra WhatsApp

Steps

1. In the Twilio Console open WhatsApp senders and click Create new sender. Pick your number and click Continue with Facebook. Finish within 60 minutes: progress is not saved.
2. Create your templates in the Content Template Builder and submit them for WhatsApp approval.
3. In Ultra WhatsApp open Numbers, click Connect a number, choose Sign up through a partner or I already have my details, pick Twilio, and paste the Account SID, Auth Token and the WhatsApp sender number in international format.
4. Point the sender's status callback and incoming message URL at Ultra WhatsApp's public Twilio address (ending in /twilio, shown under Settings, Webhook & replies). Media is sent from a public https link, as Twilio has no WhatsApp media upload.
5. Send a test template to your own number.

Good to know

• The Twilio WhatsApp Sandbox is only for testing with numbers that joined it; use a registered sender for campaigns.
• Twilio adds its own per-message fee to Meta's charges.

When Twilio makes sense

A provider can make onboarding easier and may be the account you already have, but it adds its own platform or per-message fees on top of Meta's charges. The rules stay the same either way: approved templates, opted-in contacts and Meta's messaging limits. Where the steps above set up a webhook, delivery statuses need that address saved in the provider's dashboard.

Dashboards change their menus from time to time; if a label differs, look for the API keys or developer section. Stuck? See the Ultra WhatsApp troubleshooting table, the Ultra WhatsApp user guide, or contact us.
