How to Connect an ERP Like SAP to an Approval Workflow via API
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 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.
