Re: Security error: Security header is not valid

Hi there,

 

Can you explain a little more about how/what you are trying to do.

 

What operations are you trying to do?

Are you using API calls?

Do you have a test site?

 

Cheers

Russell

Re: Security error: Security header is not valid

We have recently installed CS-Cart and are using the PayPal module to take payments. Our purchase testing crashes with this same error 'Security header not valid'. We contacted the CS-Cart support team and all they have told us to do is check the API Credentials. They provided some php (logs) but these mean little to us! Can any one help us resolve this error?

First thing to do would be to release and then regenerate your API cerdentials from within the Paypal account.

We re-installed the API configuration data and this has resolved the error.

 

Thank you.
