Can You Post to Instagram, Facebook, and LinkedIn at the Same Time?

Yes — with Postifys you can publish one approved image or video to a Facebook Page, Instagram professional account, and LinkedIn member profile in one workflow via the dashboard, API, or n8n.

Answer: You can post to Instagram, Facebook, and LinkedIn at the same time by connecting each destination in Postifys and fanning out one media asset to three platform-specific publish calls. Unified auth does not mean identical payloads — each network still needs the correct account type and fields.

Who this is for

Small businesses, agencies, and developers who want one operational layer for Meta (Facebook + Instagram) and LinkedIn without logging into three separate apps for every post.

Option 1 — Dashboard compose (immediate publish)

  1. Create a Postifys account and connect Facebook, Instagram, and LinkedIn.
  2. Open Compose, select your media, caption, and each destination.
  3. Submit — Postifys runs platform-specific jobs and records results in Post History.

Dashboard compose publishes immediately when you submit. There is no built-in marketing calendar in the compose UI.

Option 2 — REST API fan-out

Use one API key and call each platform endpoint with the same media URL but platform-specific fields:

See publish to multiple networks with one API and create a post.

Option 3 — n8n workflow

Branch one approved row into three Postifys nodes — or use the Facebook + Instagram fan-out template and add a LinkedIn branch. For timed posting, add an n8n Schedule Trigger or read a scheduled_at column from your sheet — see schedule multi-account publishing in n8n.

Frequently asked questions

Can I use the same caption everywhere?

You can reuse text, but character limits and formatting differ. Instagram captions, Facebook messages, and LinkedIn commentary should be validated per platform before fan-out.

What if one network fails?

Postifys records per-platform results in Post History. Retry only the failed destination — see recover from partial multi-platform publishing.
