# Connect Threads to X

> Connect your Threads account as the source and your X account as a destination in Post Once. From then on, the videos, photos, carousels and text posts you post on Threads go to X on their own, with your caption. Long or landscape videos skip X, because X takes short vertical videos, photos and text only.

## Before you start

- A Threads account. It does not need to be a professional account.
- An X account you can sign in to.
- A Post Once account. The free plan includes 10 reposts, with no card needed.

## How to connect Threads to X

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 **Threads** and press **Continue**.

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

3. Under **Where else should it land?**, pick **X**. Add any other apps, or a backup, then press **Continue**.
4. On **Connect your accounts.**, press **Connect** on the Threads row. Sign in on the Threads page that opens and allow access.

5. Press **Connect** on the X row. Sign in on X's page and authorize Post Once.
6. When both rows say **Connected**, press **Go to dashboard**.

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

## Already using Post Once?

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

If your bridge reads from another account, add a second bridge with Threads 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 Threads post becomes on X

| On Threads | On X |
|---|---|
| A video up to 3 minutes, vertical or square | A video post. |
| A video over 3 minutes, or a landscape one | Skipped, with "X only takes short vertical videos". |
| A photo | A photo post. |
| A carousel (its video slides are left out) | The first 4 photos, because X allows 4 per post. |
| A text post | A text post, with links written as example[dot]com. One over 280 characters is skipped with "Too long for X (280 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. When a text post has a link preview, the link's address is added to the text. Quotes, polls and GIF posts are not reposted.

X allows 280 characters, so Post Once:

1. writes links as plain text, such as example[dot]com/page, dropping https://, www. and tracking tags,
2. leaves the links out when they would push the caption past 280 characters,
3. shortens what is left to 280 characters, counted the way X counts them, and ends it with "…" when it had to cut.

## Choose what goes to X

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

- **What to post** has a switch for **Videos**, **Photos** and **Text posts**. Switch a kind off and those posts skip X, though you can still send one there by hand. Switching every kind off pauses X.
- **Rewrite caption** changes the caption for X only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit X**, 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 Threads as usual. Within about five minutes it shows up under **Your posts** on the dashboard (press **Check now** to look straight away), then goes to X. 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 Threads to X?

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 Threads posts reach X?

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

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

Post Once sends at most 50 posts per X account per day. Extra posts wait and go out once the limit resets. X only takes vertical or square videos up to 3 minutes.

### Will my text-only threads go to X?

Yes, when they fit. X allows 280 characters, and a text post longer than that, even without its links, is skipped on X instead of being cut.

### Why do links show as example[dot]com on X?

X charges apps far more for a post with a clickable link, so Post Once writes each link as plain text, like example[dot]com/page, without https://, www. or tracking tags. People can still read the address and type it in. Your other destinations get working links.
