Is "GET" form necessary for cc merch. return data

[Volitics]

Hello.

I'm trying to incorporate a credit card processing script into a web site.

The technical support tells me that in order to receive the information from the credit card gateway server I must use a form with a GET action.

In order words, when the customer inputs his credit card number, name, etc into the form on my web site the form posts (using POST method) it to the merchant account gateway. The gateway accepts the name/value pairs and then either accepts or declines the credit card.

Then it outputs name/value pairs that are supposed to be conveyed back to my web hosting server. On my server I've got an AcceptURL.php page and a DeclinelURL.php page.

The technical support person tells me that I need to have a form using the GET method (<form method="GET" .....>) on the AcceptURL.php or DeclineURL.php pages to receive the information.

He says that the GET form does not need to have a Submit button. I've never heard of using a GET form to receive variables.

What the tech support person said does not make any sense.

Does anybody know what this guy is talking about?

Thanks.

Perhaps he means it has to accept data from a form using the GET method. In other words, they don't do a POST to your page, they only will do a GET, when sending you the information.
