Posting the same content across Instagram, Facebook, and X used to mean writing it once, then manually adapting and re-uploading it two more times. Once you set up crossposting for new content going forward, that manual step disappears entirely — publish on Instagram, and Facebook and X handle themselves.

## How ongoing auto-posting works

Unlike a one-time migration of old content, this workflow watches for new posts and republishes them automatically as they go out, for as long as the workflow stays active.

1. **Connect your accounts** — Instagram, Facebook, and X — from the **Accounts** page in OneUp.
2. **Open the Crossposting menu** from the dropdown next to **Create a post**.
3. **Click Add Workflow** and set **Instagram as your source account.**
4. **Select Facebook and X as your destination accounts** — both can be added to the same workflow.
5. **Choose your content types** — decide whether Stories, Reels, and carousels should all auto-publish, or just standard feed posts.
6. **Launch the workflow.** From here, every new Instagram post automatically publishes to Facebook and X without you touching either account directly.

## What to expect once it's running

New posts typically publish to your destination accounts shortly after they go live on Instagram — you're not manually triggering anything after the initial setup. If you want to pause the workflow for a specific post (a piece of content that's genuinely Instagram-only), you can turn crossposting off per post rather than shutting down the whole workflow.

## Where this saves the most time

This setup is most valuable for accounts that already post consistently on Instagram and want the same reach on Facebook and X without doubling or tripling their content workload. Rather than writing three versions of the same post, you write one and let the workflow handle where else it goes.
