Instagram API Auto Posting

This tag focuses specifically on the technical side of Instagram's API and what it requires before any third-party tool, PostRSS included, could post to an account automatically. Instagram's Graph API only accepts posts from a Business or Creator account linked to a Facebook Page, and every image or video has to already be hosted at a public URL before the post request is made — a meaningfully more involved step than the simple link-and-thumbnail format PostRSS uses on Facebook, X, LinkedIn, and Pinterest. Articles under this tag break down those API-level requirements in detail, including why a plain RSS feed item doesn't satisfy them on its own. This is useful reading for anyone technical enough to consider building a custom Instagram integration, or who simply wants to understand why Instagram automation looks so different from the networks PostRSS already supports. Expect API mechanics and platform rules here, not marketing claims about ease of use.
