About JustCall

JustCall's REST API allows developers to programmatically initiate calls, send SMS/MMS, and retrieve call recordings and analytics. It is designed for sales teams that want to build custom dialers or automate voice-based workflows within their CRM. With its robust webhook support, you can trigger actions in real-time when a call is started, answered, or completed, making it a cornerstone for automated sales operations.
