# Connect X to Threads

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

## Before you start

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

## How to connect X to Threads

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 **Threads**. 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 Threads row. Sign in on the Threads page that opens 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 Threads.

## Already using Post Once?

If X is already the source of your bridge, open **Bridge** and press **Connect** next to Threads 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 Threads

| On X | On Threads |
|---|---|
| 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 | Skipped, with "Threads only takes short vertical videos". |
| A photo | A photo post. |
| A post with several photos | A carousel of up to 20 photos. |
| A text post | A text post. One over 500 characters is skipped with "Too long for Threads (500 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.

Threads allows 500 characters. A longer caption on a photo or video is cut at 500, sometimes mid-word, so put what matters first.

## Choose what goes to Threads

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

- **What to post** has a switch for **Videos**, **Photos** and **Text posts**. Switch a kind off and those posts skip Threads, though you can still send one there by hand. Switching every kind off pauses Threads.
- **Rewrite caption** changes the caption for Threads only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit Threads**, 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 Threads. 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 Threads?

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 Threads?

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 Threads?

Post Once sends at most 250 posts per Threads account per day. Threads only takes vertical or square videos up to 3 minutes.

### Will my text posts on X go to Threads?

Yes. Text posts go to Threads with each t.co link turned back into the full address. A text post over 500 characters skips Threads.

### My caption was cut off on Threads. Why?

Threads allows 500 characters. Post Once keeps the first 500 characters of a longer caption, and the cut can land mid-word. Put the important part at the start of your caption.
