Instagram

Prepare and review your Instagram posts.

Prepare the visual, caption and review together.

Keep the caption beside the media

Review the chosen image, carousel or Reel with its caption and required settings before scheduling.

Formats, limits and results

See the supported formats, text and media limits, required settings, platform-only features and available metrics below. These details come from the same capability data the editor uses.

Confirm the version you intend to share

A person confirms publishing by default. A workspace owner can explicitly enable auto-publish for a particular agent in a particular workspace.

Availability varies by account and format. A missing number is not zero.

More to know

  • Only professional accounts (Business or Creator) can publish through the API.
  • Captions: at most 2,200 characters, 30 hashtags and 20 @mentions (IG User Media reference).
  • Images are JPEG only, up to 8 MB, 4:5 to 1.91:1. Widths outside 320 to 1440 px are scaled by Instagram, not rejected.
  • Carousel videos: 3 to 60 seconds, up to 100 MB, 4:5 to 16:9. Today's IG User Media reference has no separate carousel video table any more (codec and frame rate match Reels), so these carousel limits are unverified as of 2026-09-28. Reels: 3 seconds to 15 minutes, up to 300 MB, 23 to 60 fps. Videos wider than 1920 px are scaled down.
  • Reels between 5 and 90 seconds at 9:16 can appear in the Reels tab; other Reels still publish as regular videos. This window comes from a third-party summary, so it only warns.
  • Alt text (alt_text, up to 1,000 characters) is documented for single images and carousel image items. Reels, carousel videos and Stories don't take it.
  • AI disclosure: the aiGenerated setting sends is_ai_generated (Instagram changelog, 2026-06-22). It isn't sent on carousel children.
  • Carousels are cropped to the first item's shape (1:1 by default) unless all items share an aspect ratio.
  • Rate limit on API-published posts per account in a rolling 24 hours (a carousel counts as one): Meta's docs disagree on 2026-09-28 (content publishing guide: 100; media_publish and content_publishing_limit references: 50). The adapter reads the live quota and falls back to 50.
  • Videos are pulled from our public URL, or uploaded with Meta's resumable upload (rupload.facebook.com) when there is no URL Meta's servers can reach. Images always need a public HTTPS URL (never localhost), so image posts can't be sent from a laptop running the local storage stand-in.
  • Metrics can be delayed up to 48 hours.

Questions and answers

Can I use every feature in the platform app?
No. Platform APIs expose only some features. The format guide identifies what you need to finish manually.
