# X

> Connect your X account to publish posts and threads.

Last updated: 2026-10-04 | Canonical: https://omnisocials.com/help-center/integrations/x

OmniSocials publishes posts and threads to X (formerly Twitter) through X's official API. X charges for API posts that contain a link, so those posts use credits. This article explains what you can publish, how to connect your account and how credits work.

## What you can publish

| Format | Details |
|---|---|
| Post | Text, up to 4 images, or one video |
| Thread | Several posts that reply to each other, each with its own text and media |

Direct messages on X can also come into your [Social Inbox](/help-center/engagement/social-inbox). This is optional and uses credits: 1 credit for each message you receive and 2 credits for each reply you send.

## Requirements

- An X account. With X Premium or Premium+, you can post up to 25,000 characters instead of 280.
- The **Manage Social Channels** permission in your OmniSocials workspace.

Each workspace connects one X account.

## Connect X

1. Click the workspace name at the top of the sidebar, then click the + button (**Add channel**).
2. Find the X card and click **Connect**.
3. Sign in to X and authorize OmniSocials.

The X sign-in can get stuck in a loop. If that happens:

1. Open x.com in another tab and sign in there first.
2. Use your X password, not "Sign in with Google".
3. Come back to OmniSocials and click **Connect** again.

To connect a different X account than the one signed in on x.com, sign out there first or use a private browser window.

When your account has X Premium, the X card shows a **Premium** badge.

## X options in the editor

Click the X icon in the channel bar to see and edit the X version of your post. Type @ in the X editor to mention an account.

- **Threads**: click **Add post below** in the toolbar to add a post to the thread. When your text is longer than 280 characters, click **Split into thread** to split it into several posts.
- **Alt text**: click **ALT** on an image to describe it. X shows alt text on images, not on videos.

The X tab of the options panel at the bottom of the editor has these settings:

| Setting | What it does |
|---|---|
| **Who can reply** | **Everyone**, **People you follow** or **Only people you mention** |
| **Paid partnership** | Shows that the post promotes a brand or business |
| **Made with AI** | Marks the post as containing synthetic content |

## Credits for posts with links

X charges extra for API posts that contain a link, and OmniSocials passes that fee on as credits, at cost.

- A post with a link that starts with http:// or https:// uses 20 credits.
- In a thread, every post in the thread that contains such a link uses 20 credits.
- Posts without a link are free. A link written without http:// or https://, such as brand.com, is also free.
- Credits are only deducted once the post publishes.

The editor tells you how many credits a post will use before you schedule it. If your organization doesn't have enough credits, the X post fails. Buy more under **Settings** > **Billing** > **Credits**.

## Limits

| | Limit |
|---|---|
| Text | 280 characters per post, or 25,000 with X Premium. Every link counts as 23 characters, and emoji and some symbols count as 2. |
| Media in a post | Up to 4 images, or one video. Not both in the same post. |
| Image files | JPEG, PNG or WebP, up to 5 MB |
| Video | Up to 140 seconds and 512 MB. X Premium accounts can post longer and larger videos. |

On X, a post needs text, media or both.

## Troubleshooting

**The sign-in loops or ends on your X timeline.** Sign in on x.com in another tab with your X password, then click **Connect** again.

**The card says Connection expired.** Click **Reconnect** and sign in to X again.

**You upgraded to X Premium, but the limit is still 280 characters.** OmniSocials reads your X plan when you connect. Reconnect X with the refresh icon on its card.

**The editor says there aren't enough credits for this X link post.** Buy credits under **Settings** > **Billing** > **Credits**, or remove the link.
