# Webhooks

Webhooks is a built-in app shipped with PreCallAI, and it doesn't need to authenticate with any other external service to run.

## How to use

You will be given a webhook URL in the test substep on the editor page, and you can use it to send a GET, POST, PUT, or PATCH request to PreCallAI to trigger the flow.
