Upload API Reference

Upload API is an addition to our REST API. It provides several ways of uploading files to our servers. Keep in mind that every Uploadcare API client provides some method of uploading files. So, if you’re not writing a library, you are likely better off using one of our API clients for a language you prefer.

Every uploaded file is temporary and subject to be deleted within a 24-hour period. To make any file permanent, you should store or copy it. You can also store a file on upload via the UPLOADCARE_STORE flag. Once uploaded, your files become available via our CDN.

The Upload API endpoint via HTTPS is https://upload.uploadcare.com/. You send us form data and receive JSON responses. All URLs must end with a forward slash /.

There also is a quick way to confirm file uploads. It originates from REST API and is about subscribing to the file.uploaded event via the webhooks endpoint. Learn more about webhooks here.
