Export forms to Storage - Forms

REST API Overview

Reference

Forms

Download API definition:

GET https://dev-api.bentley.com/forms/storageExport?ids[&includeHeader][&fileType][&folderId]

Requests that anywhere from 1 to 5 forms be exported to a file and saved in cloud-based storage for this iTwin (accessible through the Storage API). Currently 'pdf' is the only supported file type. The IDs of the forms must be specified in a query string parameter named "ids", separated by commas if there is more than one. A sample request URL that exports 3 forms to a PDF is as follows--

https://api.bentley.com/forms/exportPdfToStorage?fileType=pdf&ids=abab23524535,89458jjlij,32636wtewtwt&folderId=090909877987&includeHeader=true

Note that unlike most GET requests, this is not an idempotent operation; each time it is called, a new file will be generated. The response will not contain the file itself, but links to download it from Storage.

All forms specified in the request must come from the same iTwin, or the request will fail. The client may also specify the ID of a destination folder where the file should be saved; otherwise, it will be saved in the iTwin's root folder. They can also specify whether to include a textual header with form metadata at the top of each page (default) or exclude it.

Authentication

Requires Authorization header with valid Bearer token for scope itwin-platform.
