## Forms: update & attach files by URL

### What’s new?

* New **`PATCH /forms/{formId}`** endpoint lets you update a form’s core fields and responses in one call (status, due dates, collaborators, and individual field values).
* New **`POST /forms/{formId}/fields/file-from-url`** endpoint uploads a file from a public URL and attaches it to a specific FILE-type form field.

### Impact

* Form updates can now be performed via the public API.
* Integrations can push external documents (e.g. generated PDFs, reports, photos) directly into form fields using a simple URL-based workflow.
