Under the Hood: Vistara Connect REST Architecture

Everything Lovable will wire up into your backend application:

Programmatic Agent Management (GET, POST, PUT /api/v1/agents)

Manage conversational agent lifecycles via REST. Agents default to Hindi with native Indian speech synthesis (meera or Aoede).

Lovable Integration FAQ

How do I add AI calling to my app with Lovable?

Copy the Vistara AI integration prompt on this page and paste it into Lovable, or save it in your project as VISTARA.md and ask Lovable to follow it. Lovable then checks your Vistara account and API key, helps you create a voice agent, places a test call to your own phone, and writes the code that starts calls and receives each call's transcript, summary and extracted answers by webhook.

Can Lovable build the screens as well as the integration?

Yes. Lovable builds a backend function that starts calls and receives the webhook, plus a test-call form, a calls list with status badges and a call detail view with the summary, answers, transcript and recording. Your API key goes into the project's secrets, never into the frontend.

Is my Vistara API key safe?

The prompt never contains your key. Lovable is told to read it from the VISTARA_API_KEY environment variable, keep it out of source files, examples and logs, and use it only on the server — never in browser or mobile app code.

How much does it cost to try?

The prompt is free. New Vistara AI accounts get ₹150 free credit with GSTIN (₹50 without) — up to 200 calls, since unanswered calls are never charged. After that, calls are billed per connected minute from your prepaid wallet.
