CallRail

CallRail is a call tracking and conversation intelligence platform that attributes phone calls, texts, and form fills to marketing campaigns and applies AI-powered transcription, sentiment, and lead scoring to inbound conversations. The CallRail v3 API is a REST/JSON interface exposing accounts, companies, trackers, calls, texts, form submissions, and integrations. Authentication uses an account API key passed in the HTTP Authorization header against a base URL of https://api.callrail.com/v3/.

CallRail publishes 2 APIs on the APIs.io network: Accounts API and Calls API. Tagged areas include Call Tracking, Conversation Intelligence, Marketing Attribution, Lead Tracking, and Telephony.

CallRail’s developer surface includes authentication, documentation, pricing, signup flow, support, and 6 more developer resources.
