Checkout keeps failing

Hi,

I am trying to finalise a transaction with express checkout. I have everything set up correctly I think. I am using sandbox and I can initiate the transaction, I then log into my testing buyer account and proceed, it takes me back to the confirm page which is all filled out correctly from the token. It is when I press the Submit Order button on the pp_confirm.php page it ends up redirecting me to the pp_checkout_failure.php page.

Has anybody experienced this before and have any idea what it might be. Is there some way I can find out what error is occuring is there a log or something I can look through? I just end up on that page with no error messages or indications why. Could it perhaps be a setting I need to change in my sandbox accounts?

I am using ecart 4 and I am in Australia incase that makes a difference.

on the failure page add the following code:

<pre><?php @session_start(); var_dump($_SESSION); ?></pre>

this will write the contents of the session including the full request and full response from the gateway to help troubleshoot.


NOTE: The session contents will contain sensitive data that should be removed before posting here.

From the error listed it would appear that it will not process due to the fact that the items price does not match the cart total.

Error Message - The totals of the cart item amounts do not match order amounts.10413Error2.203926908" }

I am in Australia so the Tax is included in the price. I followed TAX rule forum here and it would appear thats the reason why it does not work. Basically the add to cart button is static and set at $30. The ecart object Total Price calculation has been adjusted by adding *(1/1.1) on to the end of the calculation. GST (tax) has been set up as total number of unique items in the cart and > than 0 is selected. Calculation is set to based on the cart subtotal and then multiplied by 0.1.

For the cart to display correctly I have also added *1.1 to the totalprice ("TotalPrice")*1.1). I have done this both on the shopping cart and checkout pages.

So although the prices appear to match in the cart and everything displays perfectly paypal will not except it. If I remove the *(1/1.1) from the ecart object Price calculation the payment goes through but the amounts are totally wrong.

So how can I get the item amount to match the cart amount? have tried to use a formula in the add to cart button but it ignores it.

Any help would be great. Also does the new ecart include australian GST inbuilt as I may look at upgrading if it does.

Hope you don't mind me adding my problems to this thread, but I have a similar problem in that the PP checkout keeps failing.
I am using the sandbox testing server; I have added the session echo to my failure page and I get:

["ECO_Process_Result"]=>
string(2254) "2013-01-22T12:03:48ZFailurecbaee1a559221Security errorSecurity header is not valid10002Error63.04181146"

I hope you can help me,

Jarrad

the error:
Security header is not valid

means that the API Credentials you entered are not correct.

The most common cause of that error is using Sand box API Credentials when sandbox mode is not enabled, or vice versa.

double check the API Credential that you entered.

NOTE: The API Username and password is not the same as your paypal account login. see the "Signing up with the PayPal payment gateway" tutorial on the learning resources page if you need more details:
