Hello everyone, I recently found a lot of people struggling to use Bitpay's Payment Protocol implementation. It was a while since they announced it and there were some solutions (decoders). But the problem with them is that they can just show you the wrong address/amount and there is no way for you to verify it.

I'm going to show you how to get the address/amount yourself.

Its quite simple. When you get payment getway, you need to get the link from there. Then you need to send a GET request to that link with header: "Accept" and value "application/payment-request" You will get JSON response with the address and amount required to pay. Now, not everyone is in tech business and knows how to do that. You will need a free tool called Postman. Download it and from there it should be straightforward.

Not a lot of wallets support BIP 70 yet, and I don't see why should anyone whose wallet don't support that switch to another one just to make payments to Bitpay. Hope I've helped someone out 🙂
