سفارش پروژه – رفع ارور از یک کد جاوا برای paypal

I am a Java developer and I’m looking for someone to debug my application to explain what I’m doing wrong with Paypal’s RestAPI. I am trying to accept payments from my discord server by sending them directly to a payment link. Let me know if you could help me out and how much it would cost.

The issue I’m having is that as soon as I go to make the payment, it just sends me to the return url and doesn’t execute the payment.

مسئله ای که من با آن روبرو هستم این است که به محض اینکه می خواهم پرداخت را انجام دهم ، مرا به آدرس اینترنتی برگشت می فرستد و پرداخت را اجرا نمی کند.
