Response page from ebs payment gateway showing just a number

[shahimadhur]

Dear team,

I have successfully managed to integrate EBS payment gateway in my zencart.

The error is that after the checkout page redirects to EBS PAYMENT GATEWAY. HERE i enter the creditcard details. If the card details are correct or wrong the ebs redirects the page to my zencart. This page just shows a number. i am assuming it is some kind of secure has number which my zencart is not showing. (See attachment)

also when i click on home. the items are still in cart.

the same error happens even if the credit card details provided are correct and amount is debitted from the account. Here with posting the code for payment page of EBS.

Your image shows that the transaction "Failed"

[shahimadhur]

hi,

thanks for quick reply. the page shows error as i have set it to get method. but why is my zen cart not displaying it properly. it just shows a random number.

even if the transaction is successfull then same result. it doesnot take me to checkout successfull page.

am i doing something wrong? sorry i am just a novice zencart programmer.

regards
madhuresh shah

Dear All,

i need your help. The update is that the EBS payment integration is completed and i am getting orders. However the return url mentioned as per EBS INTEGRATION KIT is not correct. It does not redirect to checkout success page if payment is successful.

IF the payment is failure due to wrong details the response page does not print any failure message. I think i need two things.

1) Find out the exact variable where the CHECKOUT SUCCESS PAGE IS STORE SO AS TO REDIRECT THE PAGE THERE IF TRANSACTION IS SUCCESSFUL.

2) Figure a part where i can enter the code to determine if the transaction is success or not.


CAN YOU OR ANYONE HELP IN DETERMINING WHERE WILL I GET THE PATH FOR CHECKOUT SUCCESS PAGE.

Regards
madhuresh shah
