Hey everyone,
So I'm recently new to WHMCS, but I'm also a service provider for SecureTrading and dealing with their payment interface(s)
They've recently introduced a new payment platform called STPP which they will be migrating customers onto over the next few months.
I've built up a payment module for Secure Trading STPP which I've tested and seems to be working fine with both payments & callbacks.
You will need to set up the notifications in your STPP
If you need assistance in implementing this into your WHMCS installation then please let me know, but hope that this will be of some use to the community, and if you are interested in moving to SecureTrading then pelase let me know also as I may be able to arrange preferential rates.
Regards
Phil
