Integration with Paypal Pro

I have opened a business account with Paypal. I have even registered for API user name and password . I have also upload the certificate in the certificate folder. But when i process the payment from my website it fails … Can u please help me…

More information please why does it fail. If your certificate name is cert_key_pem.txt rename it to api_certificate_pem.txt and see if that works.


Thanks for your reply

I have changed the name of the certificate. But still it fails . it tells Payment was declined by the Payment Processor…

Any reason that it was declined such as CVV code, address, postal code, etc. Is the credit card good?
