Reonic Upload API is one of 29 APIs that [Reonic](https://apis.io/providers/reonic/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Upload. The published artifact set on APIs.io includes an OpenAPI specification.

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.
