OAuth Channels
Reels, carousels and stories that reward the first three seconds.
Instagram is a visual-first feed where reach is driven by watch time and saves, not by how many hashtags you stack. Sosial schedules your Reels and carousels alongside every other channel so a single idea can ship as a 9:16 video here and a text post elsewhere.
Connect Instagram
Instagram connects with your Instagram login, no Facebook Page needed. It has to be a professional account (Business or Creator); personal accounts can't be published to by any app.
- Open Channels and select Instagram → Connect.
- Sign in to Instagram and approve publishing, comments and messages.
- You're back in Sosial with the account listed. Repeat for each account.
If you only have a personal account, switch it in the Instagram app under Settings → Account type and tools → Switch to professional account. It's free.
Limits
| Limit | Value |
|---|---|
| Caption limit | 2,200 characters |
| Carousel | Up to 20 images or videos |
| Reels length | Up to 3 minutes |
| Hashtags | 30 max: fewer, more specific wins |
The composer checks these as you type, so a post that's too long for Instagram is flagged before it's scheduled.
What works on Instagram
- Reels and short vertical video
- Carousels that teach one idea per slide
- Behind-the-scenes and product close-ups
Tips
Write the first line for the collapsed caption
Only the first ~125 characters show before "more". Put the hook there, then use line breaks to control the truncation.
Front-load the visual hook
Keep the opening frame of a Reel readable at thumbnail size: large subject, high contrast, on-screen text under six words.
Batch carousels from one blog post
Turn each section heading into a slide, and the closing slide into a soft call to action. One article becomes a week of carousels.
Avoid
- Reusing a 16:9 landscape upload. It letterboxes and loses reach.
- Copy-pasting the same caption to Instagram and X, where the tone should differ.
- Hashtag blocks of 30 generic tags that read as spam.
