360dialog WhatsApp API setup for Ultra WhatsApp

Steps

1. Sign up at 360dialog and complete the embedded sign-up, which connects your Meta business portfolio and phone number. A number already on the WhatsApp Business app can use its coexistence option: you confirm it with a QR code or a code in the app.
2. In the Hub open your number, then API keys, then Generate API key. Copy it: it is shown once, and you can create a new one if it is lost.
3. In Ultra WhatsApp open Numbers, click Connect a number, choose Sign up through a partner or I already have my details, pick 360dialog, and paste the API key and the WhatsApp number.
4. Set the webhook URL for the number in 360dialog to Ultra WhatsApp's public webhook address (ending in /webhook, shown under Settings, Webhook & replies), so statuses and replies reach the app.
5. Sync templates and send a test template to your own number.

Good to know

• 360dialog charges its own platform fee on top of Meta's message charges; check its current plans.

When 360dialog 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.
