How it works?
1. You request a new payment address from our API, with your crypto address and callback URL http://example.com/callback?invoice=1234
2. You present your customer with the payment address generated by our system
3. Your customer sends the amount to the payment address our system generated
4. Upon confirmation our system forwards the payment to the address you provided when you request the address and notifies your system via the callback URL you provided with the payment details (value, TXID in, TXID out, etc)
5. Your system confirms the payment value and grants access to the user
