Invoice payment sequence
Invoice payment sequence.
Once an invoice is created, we start monitoring its cryptocurrency address to detect inbound transactions.
  1. 1.
    The customer specifies a purchase amount and purchase currency (if necessary)
  2. 2.
    The merchant makes an API call POST /api/invoices to create an invoice​
  3. 3.
    Cryptopay responds with the invoice details
  4. 4.
    The merchant displays the payment details to the customer (a destination wallet address, an exact amount to send, a QR code etc)
  5. 5.
    The customer broadcasts a cryptocurrency transaction
  6. 6.
    Cryptopay sends the 1st callback to notify the merchant about the fact that the customer has just broadcast their transaction
  7. 7.
    Cryptopay is waiting for the transaction to be confirmed on the network
  8. 8.
    Cryptopay sends the 2nd callback to notify the merchant about the fact that the transaction has been confirmed
  9. 9.
    Cryptopay changes the invoice status from New to Completed and sends the final callback
  10. 10.
    The merchant makes an API call GET /api/invoices/:id to retrieve the invoice status
  11. 11.
    The invoice status is returned
  12. 12.
    The merchant marks the payment as successful on their side
