[url removed, login to view] payment gateway expert needed

we are trying to integrate [url removed, login to view] Hosted Checkout payment ( [url removed, login to view] ) into our php website , everything looks fine and we have a successful payment initiation , but when we submit the info to the payment gateway page, we get ( invalid request ) , there is something wrong but we can't figure out what is it.

if you did this before, please provide a url to your live work or successful project.

basically you are not going to implement the api files, its already there ,

1- you will debug it

2- find the issue

3- correct it

if we succeeded in redirecting to the payment gateway, you will get paid, otherwise NO money will be paid for guessing.

attached 2 images, one for the successful redirection ( what we want ), the other for the wrong respond ( what we get now ) .
