Hello @alwinjs28,

Could you share which server version of Mattermost you have installed? If you’re not already running the [latest version](https://about.mattermost.com/download/), we recommend upgrading. You can also wait until v4.7 is released on Feb 16th.

Here is the [API documentation](https://api.mattermost.com/) which you might find useful?
