Checkout Error

I keep getting a checkout error when i go to purchase a product. I have specified the paypal express payments, entered sandbox details from paypal but it keeps saying checkout failed. Any idea's?

add the following code to your pp_checkout_failure.php page to get the response back from the gateway to help determine why the transaction is failingL

<?php   

 if(!session_id()) session_start();  

 if($WAGLOBAL_Gateway == 1 ) {  

     echo "<p>Direct Pay: <br />";  

     echo "Full Request: ".(isset($_SESSION["PP_DirectPayment_postedValues"])?htmlentities($_SESSION["PP_DirectPayment_postedValues"]):"n/a")."<br />";

Express Process:
Full Request: n/a
Full Response: n/a

So, the error being returned from paypal is "Security header is not valid":
<LongMessage xsi:type="xs:string">Security header is not valid</LongMessage>


This error means there is an issue with the API Credentials you are supplying.

Double check that you are using Valid API Username, API Password and API Signature value.

This can also happen if you set the cart to use the sandbox and are using live api information or vie versa.

Before using the API Information, PayPal requires that you accept the billing agreement. If you have not accepted the billing agreement, you may get this error.


If you are positive that you are using valid API Information, try requesting new api credentials, sometimes the API credentials are just bad.

Hi Jason,

My fault i forgot to tick the box to say i was entering sandbox mode, and i entered the wrong info in!!!! Thanks

No worries. Glad to hear it is working.
