I have setup Paypal button on my website and my client want to block payment for some countries. Is there any option??
I recommend to not try this in code, just log into your PayPal account and do the following. This will set FOR SURE filters for your account.
Login to your Account. Click on Profile
Click on My Selling Tools
Under Getting paid and managing my risk
Look for Managing risk and fraud
Click on Update
At the bottom, look for Risk Controls
Check the radio button for Country Monitor
Click on Edit
On the Choose your Countries page
Add the countries you don't want to sell to in the My Monitored Countries
Below check the radio button for Decline
Click on Save
Note, you can also control the dollar amount that you're willing to accept.
