How integrations work

Six ways Topcalls plugs into the tools you already run.

See how integrations work
  • Function Calling

    Voice agents call any tool mid-conversation, before the caller hangs up.

  • Webhooks

    Post every call event to your stack the moment it happens.

  • REST API

    Launch calls, pull transcripts, and manage campaigns from your own code.

  • CRM sync

    Every call updates the right record, so nothing is re-typed by hand.

  • Calendar booking

    Agents check real availability and book slots on live calls.

  • Zapier & n8n

    Trigger any downstream workflow from an inbound or outbound call.

Frequently asked questions

Which integrations does Topcalls support?

Topcalls ships 683 integrations covering CRMs, calendars, help-desks, forms, spreadsheets, and messaging tools. Every integration is available to voice agents through function calling, so an agent can create a contact, book a meeting, or update a record while the call is still live.

How much do integrations cost with Topcalls?

Integrations are included in the Topcalls per-minute rate of $0.35/min, all-inclusive per-minute. There are no per-integration fees, no premium connectors, and no separate automation seats.

What if my tool is not in the catalog?

Topcalls exposes a REST API and webhooks, so any tool that speaks HTTP can be wired up in minutes. If you want it packaged as a first-party integration, book a call and the team will scope it.

Can voice agents write back to my CRM in real time?

Yes. Topcalls voice agents use function calling to update CRM records during the call, so notes, dispositions, and follow-ups land where you already work, with no post-call sync job needed.

How long does it take to connect a tool?

Most first-party integrations connect in under a minute with OAuth or an API key. Custom webhooks and REST endpoints take about as long as it takes to paste a URL.
