Attach media with a unified input
Scheduling mutations now accept a media list. Each file can be referenced by Content Library ID, Content Library name, or public URL. This replaces the legacy mediaUrl, mediaUrls, and mediaName parameters, which remain available but are deprecated.
Upload media through the API
New GraphQL mutations can add images, videos, and GIFs to the Content Library from a public URL or by uploading a local file directly.
Find fresh media for Reddit
The Content Library media query now supports the FRESH_FOR_SUBREDDIT usage filter. Use it to find media that has not been submitted or scheduled in specified subreddits.
