Hey, @FarhanIzrar .
Thank you for reaching out and posting this question!
It looks like you’re looking to find out why the transaction cannot be completed through PayPal. According to this PayPal Community thread, ‘Error: This transaction cannot be completed because it violates the PayPal User Agreement,’ there could be various reasons as to why the transaction could not be completed.
For example, there could be some country restriction(s) between PayPal and where the customer is located, or there could be an unsupported currency conversion involved with the transaction. Nevertheless, the best way to find out the exact reason would be to review the order’s timeline and reach out to PayPal’s support. From there, PayPal’s support team can help you identify the exact reason for this failed transaction.
I’d love to hear more about your business! What kinds of products are you selling? Were you able to receive PayPal payments previously?
