Hello,
I'm using Paypal rest API for integration (subscription or recurring payments) for users for my site using node js for the server. I have been running test mode (sandbox) without any problems. after that day it won't work. I have also done some googling for almost 4-5 days but haven't been able to find the solutions. I wonder what is the exact problem? my code was not have been changing.
Following error:
https://www.sandbox.paypal.com/webapps/hermes?flow=1-P&ulReturn=true&token=4RW217291M923722V&useract...
Can someone please help me?
