## Adding Custom Endpoints

To add your own API routes:

1. Create a new route file in `src/app/api/[your-route]/route.ts`
2. Export HTTP method handlers (`GET`, `POST`, `PUT`, `DELETE`)
3. Use Zod for request validation
4. Add proper error handling and status codes
5. Document your endpoint by creating a new page in `docs/api-reference/endpoint/`

<Tip>
  See existing endpoints (like [checkout-sessions.mdx](/api-reference/endpoint/checkout-sessions)) for documentation templates and patterns.
