# Kick a user from a channel

> How to remove a specific user from a channel.

Use the following parameters to drop (also known as "kick") a user from a channel when you call `viv_chan_cmd.php`:

* `access_token` - the access token with specified claims for this action

* `auth_token` - the token that `viv_signin.php` returns

  > **Note:**
  >
  > The Control active channels API can use the `auth_token` parameter in place of the userid and pwd parameters. For more information, see [Login API](../login-api).

* `user_uri` - The user's URI

* `chan_uri` - The channel's URI

* `mode` - Use kick for this action

The following example displays how to kick a user from a channel when using an `auth_token`.

* Domain: `mt1s.vivox.com`
* Issuer: `blindmelon-AppName-dev`
* Admin user: `blindmelon-AppName-dev-Admin`
* User to drop: `ip:.blindmelon-AppName-dev.jerky.@mt1s.vivox.com`
* Channel that contains the user to drop: `sip:confctl-g-blindmelon-AppName-dev.the-channel@mt1s.vivox.com`

Construct a kick from channel token with the following parameters:

> **Note:**
>
> This process requires a Vivox access token.

* vxi: `2`
* sub: `sip:.blindmelon-AppName-dev.jerky.@mt1s.vivox.com`
* f: `sip:blindmelon-AppName-dev-Admin@mt1s.vivox.com`
* iss: `blindmelon-AppName-dev`
* vxa: `kick`
* t: `sip:confctl-g-blindmelon-AppName-dev.the-channel@mt1s.vivox.com`
* exp: `1600349400`
