Instagram Reels publishing uses the Meta Graph API. The setup has more steps than TikTok or YouTube because Instagram requires a Business or Creator account linked to a Facebook page.
Supported platforms
- YouTube Shorts9:16 · up to 60s · OAuth 2.0
- TikTok9:16 · up to 180s · OAuth 2.0
- Instagram Reels9:16 · up to 90s · OAuth 2.0
The account requirement
Personal Instagram accounts cannot publish via API. You need:
- An Instagram Business or Creator account
- Linked to a Facebook page you admin
- Page connected to Clipus during OAuth
Length limits
Instagram Reels accepts videos up to 90 seconds. Clipus warns you on the publish dialog if the video exceeds the limit.
Caption
Instagram captions support up to 2200 characters. Clipus auto-fills the first 150 from the script — edit to add hashtags, mentions, or location.
What if I do not see the Page
If the OAuth flow does not show your Page, check that the Page admin is the same Facebook account you authenticated with. Reauthorize if needed.
