We’d rather you find out here than after you’ve relied on something that isn’t there yet.
Real publish delivery and OAuth are unverified against a live app
Real posting to Facebook/Instagram/X, and the OAuth handshake itself, have only been verified up to the point of a genuine API rejection using fake credentials during development — actually completing a successful post requires your own registered developer app credentials, which weren’t available to verify against before release. This is a standing limitation across every third-party integration in this product family, not specific to social publishing.
Analytics is built entirely from this install’s own publish-attempt records, not from Facebook’s, Instagram’s, or X’s own analytics APIs. Follower growth and per-post engagement metrics (likes, reach, impressions) are not implemented. What Analytics shows you is whether your posts published successfully, not how they performed.
X image posting isn’t wired up yet
Only text-only tweets are supported on X for now — image attachments work for Facebook Page and Instagram posts, not X.
