The choices were either using wabot gateway or wassenger.
But I decided to remove wassenger gateway because 2 months of wassenger you already can buy my wabot gateway.
Then you can use the gateway for a long long time without paying monthly fee.
The Demo site is online, the usage is as simple as put server credentials then turn ON/OFF on users that want to receive new order notification.
For the gateway, you can test it on demobot.visimisi.net
at the homepage you will be greeted with simple instruction how to use.
