# Connect X to Facebook

> Connect your X account as the source and your Facebook Page as a destination in Post Once. From then on, the short and long videos, photos, multi-photo posts and text posts you post on X go to Facebook on their own, with your caption.

Post Once help center, Connect two apps. Source: https://postonce.com/help/connect-x-to-facebook.

## Before you start

- An X account. Any account you can sign in to works.
- A Facebook Page you manage. Facebook only lets apps post to Pages, not personal profiles.
- A Post Once account. The free plan includes 10 reposts, with no card needed.

## How to connect X to Facebook

1. Create a free account at [app.postonce.com](https://app.postonce.com/signup). After two short intro screens, Post Once asks where you post.
2. Under **Where do you post first?**, pick **X** and press **Continue**.

3. Under **Where else should it land?**, pick **Facebook**. Add any other apps, or a backup, then press **Continue**.
4. On **Connect your accounts.**, press **Connect** on the X row. Sign in on X's page and authorize Post Once.

5. Press **Connect** on the Facebook row. Sign in with Facebook. In the permissions dialog, make sure the Page you want is selected. Back in Post Once, pick it in the **Post to Page** list on the Facebook row. With only one Page, it is picked for you. Nothing is posted to Facebook until a Page is picked.
6. When both rows say **Connected**, press **Go to dashboard**.

From then on, keep posting on X as usual. Post Once checks it about every minute and reposts each new post to Facebook.

## Already using Post Once?

If X is already the source of your bridge, open **Bridge** and press **Connect** next to Facebook in the **Destinations** card, or press **Add destination** on the dashboard. Then pick the Page in the **Post to Page** list.

If your bridge reads from another account, add a second bridge with X as its source from the bridge switcher. Free and Solo include 1 bridge, Studio 3 and Agency as many as you need. See [bridges](https://postonce.com/help/bridges).

## What each X post becomes on Facebook

| On X | On Facebook |
|---|---|
| A video up to 3 minutes, vertical or square (the first one, if a post has several) | A Reel if it runs up to 90 seconds, otherwise a Page video. |
| A video over 3 minutes, or a landscape one | A Page video, up to 2 hours, titled with the first line of your caption. |
| A photo | A photo post. |
| A post with several photos | One photo post with up to 10 photos. |
| A text post | A Page post with the same text. |

A skipped post shows the reason on your dashboard and still goes to your other destinations. See [long videos](https://postonce.com/help/long-videos) for how Post Once tells short from long.

## How your caption carries over

The post text goes with each repost, and each t.co link is turned back into the full address. Replies, reposts of other people's posts, quotes with no video or photo, polls and GIFs are not reposted.

Facebook gets the caption up to 2,200 characters. A long video is titled with the first line of the caption.

## Choose what goes to Facebook

On the **Bridge** page, the Facebook row has two settings.

- **What to post** has a switch for **Videos**, **Photos** and **Text posts**. Switch a kind off and those posts skip Facebook, though you can still send one there by hand. Switching every kind off pauses Facebook.
- **Rewrite caption** changes the caption for Facebook only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit Facebook**, and **Add your own text** at the start or end. Each one is off until you turn it on.

## Check that it works

Post something on X as usual. Within a minute or two it shows up under **Your posts** on the dashboard, then goes to Facebook. Each post shows where it went, what was skipped and why.

If a repost fails, Post Once tries again up to 5 times over about half an hour. If it still fails, you get an email, and **Retry** sends it again to just the accounts it missed. See [a post did not repost](https://postonce.com/help/post-not-reposted).

Only posts published after you connect are reposted on their own. Older ones are listed in [Your posts](https://postonce.com/help/your-posts), where you can send any of them by hand.

## Frequently asked questions

### Is it free to repost X to Facebook?

Every account gets 10 free reposts, with no card and no watermark. One repost is one post sent to all your destinations, so it counts once however many apps it goes to. After that, paid plans start at $9 a month. See [pricing](https://postonce.com/pricing).

### How fast do X posts reach Facebook?

Post Once checks X about every minute, then reposts straight away. Long videos take a few more minutes to fetch and upload.

### What are the limits of reposting from X to Facebook?

Post Once sends at most 50 posts per Page per day. Extra posts wait and go out once the limit resets. Videos can run up to 2 hours, at up to 4K.

### Can Post Once post to my personal Facebook profile?

No. Facebook only allows apps to post to Pages. Pick a Page you manage.

### I get "No Facebook Page chosen". What do I do?

Facebook is connected but no Page is picked yet. Open Bridge and choose one in the Post to Page list on the Facebook row. New posts then go to that Page.
