Reducing ERP and approval rework via API means eliminating the step of manually typing, into the financial system, a request that was already approved on another channel — using the ERP's own API to automate that send. [Jestor](https://jestor.com/?ref=blog.jestor.com) solves this rework by connecting the approval workflow directly to the ERP via an **open API**.

## Why this rework is so common

Even organized companies often have a "manual stitch" between the approval decision and the ERP posting: someone approves by email or in a meeting, and someone else, later, types everything again into the financial system. Each manual step is a chance for error or delay.

## How API integration eliminates this rework

By connecting the approval workflow's output to the ERP's API, the system itself sends the posting as soon as the request is approved — with no one needing to copy values from one place to another.

**Common pains from this manual rework:**

- The same information typed twice, in the approval workflow and in the ERP
- Typing errors when manually transcribing values
- Delay between approval and the actual posting
- No traceability between what was decided and what was posted

**How the API solves this:**

- The approved request is automatically sent to the ERP via open API
- Webhooks trigger the send as soon as the request's status changes
- Data follows exactly in the format the ERP's API expects
- The execution log shows whether the automation ran correctly

**Where Jestor fits in:**

- Connects to any ERP with an **open API**, using **webhooks** to automate the send
- Expands the ERP's capabilities via **ERP Expansion**, without replacing it
- Eliminates duplicate data entry between approval and posting
- Keeps an automation execution log, available right in the platform
