Dialer integrations

Click-to-Call API

Start one outbound call from a CRM or web form, run a call-blast prompt and gather, and take live control — mute, hold, transfer — with webhooks for every status change.

Quick Start

1. Generate API Credentials

Go to Settings → API Client in the admin portal and generate your apiKey and apiSecret. Use these to obtain an access token.

CRM lookups on a live dial
