Interakt WhatsApp API setup for Ultra WhatsApp

Steps

1. In Interakt open Settings, Developer settings, and copy the API key. Public APIs are not on the Starter plan.
2. Create templates in Interakt and get them approved.
3. In Ultra WhatsApp open Numbers, click Connect a number, and choose I already have my details. Pick Interakt from the list and paste the key. Click Test connection, then save.
4. Add each template with Templates, Add manually, with the same name and language as in Interakt.
5. For delivery statuses, start the receiver under Settings, Webhook & replies, give it a public HTTPS address, and paste the status address Ultra WhatsApp shows for Interakt into Interakt's webhook settings. It contains your secret verify token, so keep it private.
6. Send a test template to your own number with Tools, Quick single send.

Good to know

• Interakt limits sends to 300 per minute on Growth and 600 on Advanced, so set the campaign speed to match.
• Customer replies stay in Interakt's dashboard. The Ultra WhatsApp inbox receives replies from the Meta Cloud API, 360dialog, Gupshup and Twilio.
• Interakt's public API documents template sends only, so reply from Interakt's dashboard.
• Interakt adds its own platform or per-message fees to Meta's charges; check its current plans.

When Interakt 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.
