It's still a little unclear: It says that it is a POST, but the URL in the box above contains the card details. Further, the bit of text you quote goes on to say:
> ...including the query params. These params include the card number, expiration date, and CVC
> ...including the query params. These params include the card number, expiration date, and CVC
The URL they give as an example is:
https://api.stripe.com/v1/tokens?email=foo%40example.com&pay... &card[exp_month]=4&card[exp_year]=2014&card[name]=foo%40example.com&key=pk_test_6pRNASCoBOKtIshFeQd4XMUh&callback=sjsonp1390180955159&_method=POST
So are these params in the URL, or not?
