# Connect X to LinkedIn

> Connect your X account as the source and your LinkedIn profile 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 LinkedIn on their own, with your caption.

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

## Before you start

- An X account. Any account you can sign in to works.
- A LinkedIn account. Post Once posts to your personal profile, not a company Page.
- A Post Once account. The free plan includes 10 reposts, with no card needed.

## How to connect X to LinkedIn

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**.

   (Screenshot: X picked under Where do you post first? in Post Once)

3. Under **Where else should it land?**, pick **LinkedIn**. 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 LinkedIn row. Sign in with LinkedIn and allow access.
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 LinkedIn.

## Already using Post Once?

If X is already the source of your bridge, open **Bridge** and press **Connect** next to LinkedIn in the **Destinations** card, or press **Add destination** on the dashboard.

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 LinkedIn

| On X | On LinkedIn |
|---|---|
| A video up to 3 minutes, vertical or square (the first one, if a post has several) | A video post. |
| A video over 3 minutes, or a landscape one | A video post, up to 30 minutes and 500 MB. Longer videos skip LinkedIn. |
| A photo | A photo post. |
| A post with several photos | A swipeable PDF post, one page per photo, titled with the first line of your caption. Pick **Photo grid** to post up to 20 photos in a grid instead. |
| A text post | A text post, up to 3,000 characters. |

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.

LinkedIn takes captions up to 3,000 characters, and hashtags in them become LinkedIn hashtags. Posts are public, on your personal profile.

## Choose what goes to LinkedIn

On the **Bridge** page, the LinkedIn row has three settings.

- **What to post** has a switch for **Videos**, **Photos** and **Text posts**. Switch a kind off and those posts skip LinkedIn, though you can still send one there by hand. Switching every kind off pauses LinkedIn.
- **Carousels** sits under **Photos** and decides how a post with two or more photos goes to LinkedIn: **Swipeable PDF**, the default, which people swipe through like a carousel, or **Photo grid**. It shows while **Photos** is on.
- **Rewrite caption** changes the caption for LinkedIn only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit LinkedIn**, 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 LinkedIn. 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 LinkedIn?

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 LinkedIn?

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 LinkedIn?

Post Once sends at most 25 posts per LinkedIn profile per day. LinkedIn access also ends after 60 days: Post Once emails you 5 days before, and you reconnect with one sign-in. Videos can run up to 30 minutes.

### Why does my carousel go to LinkedIn as a PDF?

LinkedIn has no swipeable photo post outside of ads: several photos in one post show as a grid. A PDF is how people post carousels on LinkedIn. Each photo becomes one page at its own size, and people swipe through the pages in the feed. To post the grid instead, pick Photo grid under Carousels on the LinkedIn row. To post one by hand, read [how to post a carousel on LinkedIn](https://postonce.com/blog/how-to-post-carousel-on-linkedin).

### Why do I have to reconnect LinkedIn?

LinkedIn gives apps access for 60 days and does not let them renew it. Post Once emails you 5 days before it runs out, and the LinkedIn row shows a Reconnect link. Reconnecting takes one sign-in. See [reconnect an account](https://postonce.com/help/reconnect-an-account).
