# Import SSL certificate

`POST /SSL/upload_cert`

This function uploads a certificate.

**Important:**

* Due to the limited field length of HTTP GET method calls, you **must** use the HTTP
POST method. For this reason, you **cannot** use a cPanel or Webmail session URL to
call this function.
* When you disable the Calendar and Contacts, Receive Mail, Web Disk, Webmail, and
Web Server [roles](https://go.cpanel.net/howtouseserverprofiles#roles),
the system **disables** this function.
