Vapi Webhook / Server URL Setup
Configure server URLs to receive real-time events from Vapi during calls — transcripts, tool calls, status changes, and end-of-call reports.
Setup: Ensure
VAPI_API_KEYis set. See thesetup-api-keyskill if needed.
Overview
Vapi uses "Server URLs" (webhooks) to communicate with your application. Unlike traditional one-way webhooks, Vapi server URLs support bidirectional communication — your server can respond with data that affects the call.
