Setup Crypto

Join Markt supports Cryptomus and NowPayments for crypto checkout.

Cryptomus

Routes under /api/cryptomus/:

create-invoice
payment-info
qr-code
verify-payment
webhook

NowPayments

Routes under /api/nowpayments/:

create-payment
payment-info
qr-code
webhook

There is no separate verify-payment route for NowPayments in the current tree — settlement is webhook-driven.

Setup

Enable the gateway in Payment methods and enter merchant credentials.
Point the provider webhook to your deployment path.
Test with small amounts; confirm order moves to paid/completed and delivery unlocks.

Amount validation applies on create paths — do not trust client-supplied totals that disagree with the order row.
