Webhook
A webhook is an HTTP request one system sends to another when something happens, so the receiving system learns about events without polling.
For a voice platform, typical webhook events are a call starting or ending, a transcript becoming available, or an agent capturing a field such as an appointment time. Your server receives the event and can update a CRM, send a confirmation or trigger the next step in a workflow.
Signed webhooks include a signature the receiver checks, so it can trust that the event really came from the platform.
