Reonic

Reonic Upload API

Two-step uploads for endpoints that accept user-provided file content. Call `POST /uploads/create` to obtain an `uploadUrl` and an `uploadId`. `PUT` the raw file body to `uploadUrl` within 1 hour, with a `Content-Type` header matching the file — not `multipart/form-data`. Then reference the `uploadId` from a registration endpoint such as those in [**Files**](#tag/files) or [**Photogrammetry**](#tag/photogrammetry) to attach the file to a resource. Prefer this flow over a registration endpoint's `url` shortcut when the file isn't already hosted at a public URL, or when you'd rather not expose it on the internet.

      summary: Create upload URL
      description: 'Returns an `uploadUrl` plus an `uploadId` you can later pass to a registration endpoint.


        Upload your file with a single `PUT` request to `uploadUrl`, sending the raw file bytes as the request body and a `Content-Type` header that matches the file. Do not use `multipart/form-data`. The URL stops accepting uploads after `expiresAt` (1 hour after creation).


        Once the upload completes, reference `uploadId` from a registration endpoint — for example `POST /files/create`.
