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.

Webhooks or notifications

Payrails sends its notification URL to MODO with every payment, so you don’t need to set one up with MODO. Payrails verifies each notification with the signing keys MODO publishes and also checks the payment status with MODO until it reaches a final state.

Request fields for MODO

Send these fields in the authorize request, in addition to the standard authorize fields. Required fields must be present for the payment to succeed. Payrails sends Optional fields to MODO when you include them. For more about meta fields, refer to Meta fields. MODO payments are captured straight away, so use instant capture in your workflow.

Configure MODO settings

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

Enable the integration

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

Next steps

  1. Run a test payment in ARS in the MODO pre-production environment, and pay it with the MODO app.
  2. Verify that:
    • Your customer sees the MODO QR code or app link.
    • The payment status updates correctly in Payrails.
  3. Once verified in test mode, repeat the setup in live mode.
