This guide shows you how to Reset the API keys.
Note : If the server is connected with WHMCS, you must update the key and pass on WHMCS also.
You can Reset the API keys from Virtualizor Admin -> Configuration -> Server Info.
On that page you will find a button "Reset API keys".
The following is a screenshot of the Server Info page.
Note :If you are resetting the keys in Master server, then it will be updated in Slave Server automatically. Once you have reset the API keys, make sure you update the keys in your API application or WHMCS plugin.
