I did some market research because I love glasses so much, and to compensate me for my time I received two giftcards from the market research company. They’re made by GiftCardPlanet.com.au and work just like EFTPOS but with stored value, which is pretty convenient.
They have this website for checking the remaining balance. It’s easy, but it’s a nuisance needing to “log in” every time. The site looks kinda janky, so I thought I’d go poking to see if I could just hit a URL instead.
Handily, the ASP backend doesn’t care whether you pass parameters as POST or GET variables, and also doesn’t mind if you don’t pass in the various junk parameters that the page was sending. Score!
If you hit this URL you’ll get a full list of transactions against the card along with its current balance, no browser state needed. Sweet!
Caption: This was a $30 card, it’s all burnt out now so there’s no reason not to share it.
Substitute in your own card’s details and you’re good to go.
