## How to Post All Your Existing Instagram Posts to Facebook, Snapchat, and X

Re-downloading every Instagram post and uploading it to Facebook, Snapchat, and X by hand isn't a great use of an afternoon.

With [OneUp](https://www.oneupapp.io/)'s crossposting workflow feature, you can automatically send all your existing Instagram posts to Facebook, Snapchat, and X — spaced out over time so they don't all publish at once.

* * *

**Step 1: Connect Your Social Media Accounts**

Head to the **Accounts** page in OneUp and make sure you've linked:

- Your **Instagram** Business or Creator account
- Your **Facebook** Page
- Your **Snapchat** account
- Your **X** account

Follow the OAuth prompts to authorize each one.

* * *

**Step 2: Open the Crossposting Menu**

1. From the top navigation dashboard in OneUp, hover over the dropdown next to **Create a post**.
2. Select **Crossposting**.

**Step 3: Build Your Auto-Post Workflow**

1. Click **Add Workflow**.
2. Set **Instagram** as your source account (the platform you're posting _from_).
3. Under content type, choose the post types you want carried over.
4. Select **Facebook**, **Snapchat**, and **X** as your destination accounts.

> **Platform tip:** X's API access tier can limit how many posts get pulled per month, which may throttle how far back a large workflow reaches.

* * *

**Step 4: Configure Timing & Finalize**

Choose how much time to leave between each post so they trickle out instead of publishing all at once. Then click **Create Workflow**.

* * *

**Why Use OneUp for Crossposting?**

You can pause, edit, or expand the workflow later as your destination strategy changes. Get started at [oneupapp.io](https://www.oneupapp.io/).
