Webhook

An HTTP callback your system sends when an event happens.

In one sentence

A webhook is an outbound HTTP request your system sends to a third-party URL whenever a defined event happens, so downstream systems can react without polling.

When it matters

When you want a fast, language-agnostic integration that pushes data into a CRM, ticketing system or chat tool the moment it happens.

A real-world example

helpcode emits a webhook every time a conversation closes — payload includes the full transcript, citations, and any tool calls.
