REST API for Developers

An API and an MCP server for everything in your dialer

Push leads in, pull calls out, send texts from your AI agent and react to events with webhooks. The API follows the same rules as the app, so DNC lists and quiet hours always apply.

Why it matters

What rest api for developers does for your team

  • 01

    Covers the whole app

    Contacts, tags and fields, texts, calls with recordings and transcripts, campaigns and their leads, tasks and callbacks, team, workflows, voicemail, reports and payments.

  • 02

    Scoped keys

    Give each key none, read, or read & write per area. Only a hash is stored, and revoking a key cuts off its access and webhook subscriptions.

  • 03

    Built for AI agents

    Send texts as a named sender like "AI Assistant". Your team sees who sent it in the inbox; the contact only sees your number.

  • 04

    MCP server for AI assistants

    Connect Claude, ChatGPT or Cursor in a minute and ask in plain words: build and publish a workflow, move contacts between campaigns, text a lead, pull last week's numbers. The assistant can do everything you can in the app, as you.

FAQ

REST API for Developers questions

Where is the API documentation?

The API reference is public and generated from the live API, so it always matches what's deployed. It's linked from the footer of this site.

Can I run the dialer from Claude or ChatGPT?

Yes. Add the MCP server as a custom connector, approve it once, and the assistant can do everything you can do in the app with your permissions. Every change it makes is logged as made through an AI assistant, and you can disconnect it any time.

Can the API bypass compliance rules?

No. The API wraps the same services the app uses, so the do-not-call list, STOP opt-outs, do-not-disturb, quiet hours and your plan limits all apply.
