# Webhooks Gravity has API routes and a `webhookController` pre-configured for you to start accepting webhooks from external services and APIs. A Stripe webhook handler is included for you and is used to handle accounts [downgrading their plan to free](/gravity-server/free-accounts.md#downgrading-to-free) at the end of their current billing cycle. Please refer to the Stripe documentation for the latest information on testing [Stripe webhooks](https://docs.stripe.com/webhooks). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
