Edit File (Sync)

Edit a file synchronously, waiting for the result before returning. This endpoint has a **5-minute timeout** β€” if processing takes longer, the request will fail. **Note:** This endpoint is intended for onboarding and testing only. For production workloads, use `POST /edit_runs` with [polling or webhooks](https://docs.extend.ai/2026-02-09/developers/async-processing) instead, as it provides better reliability for large files and avoids timeout issues. The Edit endpoint allows you to detect and fill form fields in PDF documents. For more details, see the [Edit File guide](https://docs.extend.ai/2026-02-09/product/editing/edit).
