Uploadcare URL API Reference

Every uploaded file is immediately available on the Uploadcare CDN. The CDN includes on-the-fly processing features and can work as a proxy.

You can add CDN operations by including directives in the CDN URL: https://:subdomain.ucarecd.net/:uuid/-/:operation/:params/:filename

• :subdomain is your project’s subdomain — find it in Delivery.
• :uuid stands for the unique file identifier, UUID, assigned on upload.
• /-/ is a mandatory parsing delimiter to divide operations and other path components.
• :operation/:params/ is a CDN operation directive with parameters.
• :filename is an optional filename you can add after a trailing slash /.

You can stack two and more operations like this: -/:operation/:params/-/:operation/:params/

You don’t have to code most of the low-level API interactions. We have high-level libraries for all popular platforms.
