Parameter: `cxt` · Category: Social · Vendor: X (formerly Twitter)

> cxt is **an opaque token on some X post links**, most often seen on links opened from a notification or an email from X. X has not documented it. The post is addressed by the id in the path, and LinkClean strips `cxt` on x.com and twitter.com.

## What cxt looks like

A post link with it reads `x.com/user/status/1234567890?cxt=HHwWgsC9…`: a block of letters and digits that changes from link to link. **X publishes no description of the parameter.** The name suggests "context", meaning where the click came from, and that is an inference.

The value does not identify the post. The number after `/status/` does.

## The other parameters on an X link

A link copied from the X app usually carries `s=` and `t=`, the share tokens covered on the [s parameter page](https://linkclean.app/trackers/s-twitter/). `ref_src` and `ref_url` appear on links from embedded posts. `cxt` is the one that tends to arrive through notifications. LinkClean removes all of them on X's domains.

## How LinkClean removes it

Default-on, scoped to `x.com` and `twitter.com`. Three letters are too generic to strip everywhere, so on any other site `cxt` is left alone. AdGuard's filter, Brave and Firefox remove it on X as well.

## Example

Looks like this in a URL: `https://x.com/user/status/1234567890?cxt=HHwWgsC9gbOxyz&lang=en`

After LinkClean: `https://x.com/user/status/1234567890?lang=en`

## Frequently asked

**What does cxt mean on Twitter?**

X has not said. It is an undocumented token, and the name suggests it records the context of the click.

**Does the post still open without cxt?**

Yes. The post id in the path is all the link needs.

**Why is cxt only removed on X?**

Because the name is short enough to be an ordinary key on other sites. LinkClean strips it only where it is known to be X's.
