Hello.
I need only one page in PHP about verifying payment at [login to view URL] (payment processor)!
You should register at this site (totally free) and test "Webhook Simulator" in Settings->Alerts tab. I do this by site's sample, but I always receive "Invalid".
This is very simple task for who has written payment gateway already.
HI, I can integrate paddle payment in PHP file for you. Please send me you PHP file you tried with and contact me so we can discuss more an I can imlpement it for you now.
Regards,
Tan.
Give me FTP/ssh/git access to your website and I will make Paddle work right now, I am already experienced with other payment gateways so I am confident I can do it.
Best regards, Maxim.
