Haii,
After integrating pay pal payment gateway, API response : "Payment Error : (10002) - Security error -security header is not valid" with my account credentials but working fine with other credentials. Is there any configuration (like permission) i have to do in my business account.
I tried to grant 3rd party permission to the user, Getting error like "Please enter valid API username" with my API Username.Do i have to create any user?.
Please suggest a solution for the same,
Thanks in advance
Husni
