It would be nice is someone would put up a video, so we can understand the whole process .... so I am not sure to understand the concept fully, this is how I understand it so far:
- you press the pay button
- you go manually to your own wallet, where you make the actual payment
- the http://www.steempayments.com site monitor if the payment went into the blockhain,
- if yes, display it and the go back to callback url.
If so there should be some kind of message that you have to make the actual payment from the steemit waller, after your press the 'donate/pay' button, otherwise people will just wait, because it's not really clear what you have to do next.
Maybe I misunderstood the concept .... Your thoughts on that ?
