What you can do once connected
- Publish photo posts to your Instagram Business account.
- Post Instagram Reels from a single vertical video.
- Post carousels of up to 10 photos as a single Instagram post — how carousels work.
- Get an Instagram-tuned caption and hashtag set from the AI, or write your own.
- Read and reply to your Instagram comments from the shared engagement inbox.
- Send the same upload to Facebook, TikTok and more in one action — a vertical video reaches YouTube Shorts too.
- Schedule ahead or publish from a Telegram chat.
What you need
- An Instagram Business or Creator account (a personal account won't work for publishing — switching is free in the Instagram app).
- That account linked to a Facebook Page you manage (Instagram's own requirement for publishing tools).
- Admin access to that Facebook Page.
How to connect
- Make sure your Instagram is a Business/Creator account and linked to your Facebook Page.
- In SOSPosting, open Integrations and connect Facebook.
- We automatically detect the Instagram Business account attached to your Page.
- Enable it — Instagram now appears as a publish target.
- For DMs: connect Instagram itself as well, from the same Integrations page. Publishing works without this; replying to DMs does not.
Good to know
- Instagram requires a business/creator account for all third-party publishing — this isn't specific to SOSPosting.
- Reels are published with platform-correct vertical formatting and metadata.
- DMs and comments both land in the inbox — but they take two different connections. Comments arrive as soon as your Facebook Page is linked. Instagram DMs arrive through Instagram’s own messaging webhook, and to see who wrote in and send your reply back you also need to connect Instagram directly, which is a separate step in Integrations. Link only the Page and DMs still appear, but each one shows as an unnamed sender and replies will not send.
- Failed deliveries refund their tokens automatically.
Connect Instagram or browse all integrations.
