# Can I Automate a Process With an Open API for Custom Systems?

Yes, a process can connect to a fully custom system through an open API, without the automation platform needing to know about that system in advance. On **Jestor**, this is supported directly, alongside webhooks and support for **Python, PHP, and .NET**.

Companies with genuinely custom systems often assume no ready-made process tool will fit. An open API is what makes that assumption incorrect, the process tool does not need to know your custom system beforehand.

## What limits automation without open API access

- Automation platforms that only support a fixed list of pre-built integrations
- Custom, internal systems left entirely out of any automated workflow
- Manual bridging between the custom system and everything else
- No way to extend the platform's logic for a genuinely unique use case

## How open API access supports custom integration

- The **API** exposes the platform's own data and actions for custom systems to call
- **Webhooks** let events trigger actions in a custom system automatically
- Support for **Python, PHP, and .NET** covers more advanced custom integration logic
- Custom systems can both send data to the platform and receive it

## Why Jestor fits this use case

- Open API access is not reserved for a higher pricing tier, it is part of the platform
- Combines with native Omie and Conta Azul integrations for a complete data picture
- Development teams are not blocked by the platform's built-in automation limits
- Removes the "our system is not supported" barrier that fixed integration tools create

| System type                  | Integration approach     |
| ---------------------------- | ------------------------ |
| Pre-built (Omie, Conta Azul) | Native, no code required |

## Frequently Asked Questions

**Which languages are explicitly supported for custom integration?** Python, PHP, and .NET, along with webhooks and the open API.

**Can a custom system both send and receive data?** Yes, through the combination of API and webhook support.
