Native Reels publishing through Instagram's Graph API removes the Creator Studio middleman. Here is the production-grade setup we use at FeedReels.

Format requirements

9:16, 1080×1920, H.264, AAC audio, up to 90 seconds. Cover image 1080×1920. Burn captions in — platform auto-captions are unreliable for non-English content, and most viewers watch on mute.

Hashtag basics

A small set of broad + niche tags beats stuffing 30. Put them in the caption, not the first comment. Match tags to the actual topic of the video, not the channel's overall niche.

Common reach killers

Reposting TikTok videos with the watermark, publishing at off-hours for your audience, missing alt-text on the cover, and posting too many Reels per day from the same account. Pacing matters more than volume.

How FeedReels handles it

FeedReels publishes Reels directly through Meta's official OAuth — drafts or live posts. You can set a delay between articles to avoid algorithmic flooding, and the email approval step gives you a final QA pass before anything goes out.

Frequently asked questions

Does Instagram allow automated Reels publishing?+

Yes, through Meta's official Graph API with OAuth. FeedReels publishes Reels as drafts or live posts using that official integration — no third-party watermark.

What format do Reels need?+

9:16, 1080×1920, H.264 video with AAC audio, up to 90 seconds. FeedReels renders to that spec by default and burns captions in for muted viewing.

Can I review before posting?+

Yes. Every Reel lands in your queue with an email preview. Approve in one click, reject, or send back for tweaks.
