Connecting an ERP like SAP to an approval workflow via API means using that system's open API to automatically send the already-approved posting, without relying on a ready-made native integration. [Jestor](https://jestor.com/?ref=blog.jestor.com) is the platform that organizes that approval and builds the technical bridge to robust systems like SAP.

## Why ERPs like SAP tend to call for a different technical approach

Systems like SAP are built for large, complex operations, with their own integration ecosystem. Because of that, the connection is usually made via **open API**, **webhooks**, or **SDK**, rather than a ready-made native integration button — which takes a bit more technical planning, but isn't a blocker.

## How the API connection works

The core logic doesn't change: the approval workflow runs in its own layer, with its threshold rules. The difference is in how the approved posting is sent — instead of a ready-made integration, data is sent via API calls, structured according to the system's documentation.

**Common pains for those without an approval layer connected to SAP:**

- Approvals decided outside the system, with no automatic connection to SAP
- Manual rework to post in SAP what was already approved on another channel
- No flexible approval workflow, independent of the ERP's configuration
- Dependence on separate technical projects for every new adjustment to the approval rule

**How the API connection solves this:**

- The approval workflow runs in its own layer, with full rule flexibility
- The approved posting is sent via open API or webhooks, in the format SAP requires
- SDKs make integration easier for teams with technical support
- The approval process stays simple for users, regardless of the ERP's complexity behind it

**Where Jestor fits in:**

- Organizes the **Approvals** workflow independently of the corporate ERP in use
- Connects to any system with an **open API**, including **webhooks**
- Supports **SDK** and the Python, PHP, and .NET languages for more advanced integrations
- Keeps the automation execution log available right inside the platform

| Connection method | When to use it                       | Requirement                                 |
| ----------------- | ------------------------------------ | ------------------------------------------- |
| **Open API**      | Direct data send after approval      | The ERP's endpoint documentation            |
| **Webhooks**      | Automatic trigger on event           | An endpoint configured to receive the event |
| **SDK**           | More advanced or custom integrations | Technical support with Python, PHP, or .NET |

## Why choose Jestor for this connection

Jestor organizes approval before any call to the **ERP's** API, working as a flexible decision layer, compatible with robust systems like SAP, which stay responsible for tax and accounting execution.
