How does CryptAPI work?

You request a new payment address from our API, with your crypto address and a callback URL such as https://example.com/callback?invoice=1234.
You show your customer the payment address our system generated.
Your customer sends the amount to that payment address.
Once the payment is confirmed, our system forwards it to the address you gave when requesting the payment address. It also notifies your system through the callback URL, with the payment details (value, TXID in, TXID out, and so on).
Your system checks the payment value and gives the customer access.
