Remote licence

Hi all,

I have an EA that I would like to protect for my wp users. I’m looking for a remote license soulition to control the licences of the EAs and restrict the usage if a predefinied time has expired.

EA need to check the validity of the license key online from my webserver db, at every starts. 

So EA should connect to an api that reads the data from my website database and check the time limit for using EA.

Wp plugins are preferred.

Now I use:

//---Time Lock
   datetime Expire_Time = D'2021.03.03';//YYYY.MM.DD
   if(TimeCurrent()>=Expire_Time || TimeLocal()>=Expire_Time) {

..but need to manage it remotely.
