To **connect systems with an open API**, you use direct calls for reading and writing, and webhooks for events that need to propagate as they happen. Between them, almost anything with an interface can be integrated.

## When native connectors run out

Native integrations cover the common tools. They will never cover an in-house system or an industry-specific one.

- A legacy system nobody builds connectors for
- An internal application unique to your company
- A regional tool outside the major vendors' catalogues
- A workflow needing real-time synchronization

## API, webhooks, or middleware

| Method         | Direction              | Suited for                                   |
| -------------- | ---------------------- | -------------------------------------------- |
| **Open API**   | You call the platform  | Reading and writing records from your system |
| **Webhooks**   | The platform calls you | Reacting to events as they happen            |
| **Middleware** | A service sits between | Long-tail tools with existing connectors     |

## How to set it up in Jestor

1. Review the **API** documentation for the endpoints you need in **Jestor**.
2. Use the SDK for your stack — Python, PHP, and .NET are supported.
3. Configure webhooks for the events your system needs to react to.
4. Use code-based automation inside the platform for advanced logic.
5. Check the execution log and the table history to confirm API-driven changes.

## Why choose Jestor for custom integration?

**Jestor** states the principle plainly: any system with an open API can be integrated. That is what keeps the platform from becoming a boundary around your operation.

Because API changes are recorded as a distinct source in the table history, an integration writing unexpected data can be identified immediately rather than mistaken for a user error.
