Re: RealTime online credit card verification

Hi,
	Sorry, I was not clear enough about my problem.
	What I need is:

		minivend will save consumers info such as credit card
		number, expiry date, card holder's name, the amount of
		money to be charged. Basically, I need to pass all of
		these variables to my cgi script. I don't know how to
		find out all these variables names. Will something like
		this work for me?(I am only guessing)

		geturl ("http://__CHECKURL__?action=submit&creadit_card_number=$mv_ccnumber")

		Also, once my own cgi script has verified the credit
		card and charged the money on it, what should I tell
		minivend so that it knows that this process has
		completed successfully.

	Maybe this is the answer to my question above. I will have a
	look at the docs again.

	I don't think this is what I want/need.

	I don't really know, not even how to check it out.
	But thanks a lot anyway.
