Checkout error message

Recommended Posts

Hi,

Have just created a new website and all seems to be as I want it to be but on testing it (from a different device) an error message comes up when trying to pay via PayPal for the items ordered.

The error message is displayed in a big red banner and it says  The following errors were detected: Error: Security header is not valid Security error.

Any ideas why this is happening and what do I do to correct it?

 

Also, is there any way of changing it so that they only have the option of paying by PayPal and not debit/credit card?

Thanks

A quick search via Google shows the following !

The "Security header is not valid" error message is only caused for two reasons:

  1. Wrong credentials Make sure that you've put your API Username, API Password and API Signature correctly. Sometimes it happens that during copy and paste there is accidentally a space added, this would trigger this error.Double check this settings in the SDK or in the admin panel of your third party shopping cart.
  2. Wrong Endpoint This error would come up if you send the data to the wrong endpoint. Make sure that you sending the live credentials and data to our live endpoint. When you want to test your store make sure that you use our test endpoint and the credentials from your sandbox test account.If you are using a third party shopping cart, make sure that your store is running in test or live mode, regarding which credentials you are using.
