The Talkover API lets you place and receive phone calls handled by voice agents — autonomous LLM-driven assistants that follow your instructions, run integrations during the call, and deliver structured results back to your system.

​
What you build with it

  • Inbound agents that answer your phone numbers and handle support, scheduling, or qualification.
  • Outbound agents that follow up on form submissions, confirm appointments, or run surveys.
  • Campaigns that dispatch outreach at scale with retry rules, time windows, and DNC lists.
  • Webhooks that push events to your system so you can correlate calls with internal records.

​
Two ways to place calls

There are two endpoints for outbound calls. Pick based on intent:
  • Make a call — one-off, dispatched immediately. Use for hot leads, callbacks after a form submission, or any flow where the call is triggered by a single user event.
  • Make a campaign call — queued under a campaign. The campaign enforces working hours, retry policy, and DNC. Use for batch outreach.
Both return a call_id you can track via List calls or webhook events.

Where to start

  1. Quickstart — first call in a few requests.
  2. Authentication — environment tokens vs account tokens.
  3. API reference — full endpoint catalog.
