Accept crypto through your own NOWPayments account. You bring the account and funds settle to your NOWPayments balance — NOWPayments charges a 0.5–1% service fee, and Komerza adds nothing on top. Komerza connects using your API key and IPN secret, and registers the payment webhook automatically — there’s no callback URL for you to configure.

​
Prerequisites

  • A NOWPayments account (free to create).
  • A payout wallet address — NOWPayments won’t issue an API key until one is saved on your account.
1

Add a payout wallet and create an API key

NOWPayments requires a payout wallet before it will generate API keys.
  1. Log into your NOWPayments dashboard.
  2. Go to Store Settings → Payments.
  3. Enter your payout (outcome) wallet address and click Save.
  4. Scroll up to the API keys section and click Add new key.
  5. Copy the new API key.
2

Generate your IPN secret

  1. Still under Store Settings → Payments, scroll to Instant Payment Notifications (IPN).
  2. Generate the IPN Secret key and copy it.
NOWPayments shows the IPN secret only once. Copy it before leaving the page — if you lose it, generate a new one and update it in Komerza.
3

Connect NOWPayments in Komerza

  1. In your dashboard, open Settings under Online Store, then go to Cryptocurrency.
  2. Under Processors, find NOWPayments and click Connect.
  3. Paste your API key and IPN secret, then save.
Komerza automatically registers the payment webhook with NOWPayments — you don’t need to add a callback URL anywhere.Connect NOWPayments in Komerza
4

Route your coins to NOWPayments

On the Cryptocurrency page, open Coin routing and set each coin you want NOWPayments to handle to NOWPayments — or confirm default routing already points there.
5

Test the connection

Make a small test payment on your store to confirm NOWPayments processes it and the order is marked as paid before you go live.

​
How it works

  1. A customer picks a NOWPayments-backed coin at checkout.
  2. NOWPayments handles the payment and funds settle to your NOWPayments balance.
  3. NOWPayments sends an IPN callback; Komerza validates it with your IPN secret and marks the order paid, triggering delivery.
