  3. Select Add instance to create a new integration configuration.
  4. Select the workspaces where this integration should be available.

Step 1: Choose the integration type

  • Select Payment.
  • Continue to the next step.

Step 2: Choose the provider

  • Select Nuvei.
  • Continue to the next step.

Step 3: Configure your Nuvei integration

What you’ll need from NuveiBefore you begin, make sure you can log in to the Nuvei Control Panel. You’ll copy your merchant ID, merchant site ID and merchant secret key from it.

Integration instance name

An integration instance is a specific payment provider setup in Payrails. You can create multiple instances for different regions, currencies, or business needs. Choose a clear, consistent name, as it is used in routing.
In Payrails
  • Enter an Instance name for your integration, for example merchant_nuvei.

Account details

  • In the Nuvei Control Panel, copy your Merchant ID and Merchant Site ID.

Credentials

In Nuvei
  • Copy your merchant secret key from the Nuvei Control Panel.
In Payrails Payrails sends requests to Nuvei’s test environment in test mode and to Nuvei’s live environment in live mode, so use the merchant secret key for the matching environment. A screenshot showing the Nuvei credential fields.

Payment methods

In Payrails Card, Apple Pay and Google Pay have extra settings inside their card once you select them. Refer to Configure Nuvei settings. A screenshot showing the Nuvei payment method selection.

Webhooks or notifications

Payrails sends its notification URL to Nuvei with every payment, capture, void and refund, so payment notifications (DMNs) need no setup in the Nuvei Control Panel. Payrails verifies each DMN with your merchant secret key. To receive chargeback and fraud notifications, ask Nuvei to send chargeback DMNs to your Payrails notification URL. Copy it from Notification URL under Account configuration at the top of the integration form.

Request fields for Nuvei

Send these fields in the authorize request for card payments, in addition to the standard authorize fields. Required fields must be present for the payment to succeed. Payrails sends Optional fields to Nuvei when you include them. For more about meta fields, refer to Meta fields.

Configure Nuvei settings

Some Nuvei integration settings change how Payrails processes your payments. The portal shows the same description when you hover over each setting.

Account settings

These settings are under Account details.

Payment method settings

Payment method settings appear in each method’s card after you select it. A screenshot showing the Nuvei Apple Pay settings. For more about meta fields, refer to Meta fields.

Enable the integration

In Payrails
  • Select Save account to enable the integration.
  • Confirm the integration shows as Enabled.
Your Nuvei integration is now ready to process payments.

Next steps

  1. Run a test payment using a Nuvei test card.
  2. Verify that:
    • The payment appears in the Nuvei Control Panel.
    • The payment status updates correctly in Payrails.
  3. Once verified in test mode, repeat the setup in live mode.
