OpenPost checks the text and media rules for the format you choose. | Format | Text | Media | | --- | --- | --- | | Feed image | 2,200 caption characters | One public HTTPS image | | Carousel | 2,200 caption characters | 2-10 public HTTPS images or videos | | Story or Reel | No Story caption; 2,200 for Reel | Public HTTPS media required | ### Provider limits and scope - 2,200 caption characters - One image/video or a 2-10 item carousel - Feed, carousel, Story, and Reel profiles - Business or Creator accounts connected to a Facebook Page - No text-only posts Connect and test ## Set up Instagram in three checks. 1. Connect an eligible Instagram Business or Creator account to a Facebook Page. 1. Set up the Instagram app, permissions, callback address, and public media address. 1. Choose the Instagram account during sign-in and test each format with it. Known limits ## What can still block a post. - OpenPost does not support text-only Instagram posts. - Media must be public HTTPS and meet Meta format rules. - App access and each planned format still need a live account test. **Account requirement:** An Instagram Business or Creator account connected to a Facebook Page. **Verification:** Test each planned format—feed, carousel, Story, and Reel—because one successful format does not prove the others. ## Use the current callback address, permissions, and media setup. Social network developer pages change. The OpenPost guide lists the settings and checks you need now. [Read the Instagram guide](https://docs.openpo.st/providers/instagram)
