​
Webhooks or notifications

Payrails uses provider webhooks or notifications to receive asynchronous payment status updates.
Create webhooks in the same mode (test or live) as your Payrails integration.
In Payrails
  • Copy the Notification URL shown under Account configuration at the top of the integration form.
In N-Genius
  1. Go to Settings → Integrations → Webhooks and add a webhook with the Payrails notification URL.
  2. Add a custom header: use the same key and value you entered in Notification header key and Notification header value.
  3. Save the webhook.

​
Request fields for Network International

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 Network International when you include them. 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 Network International integration is now ready to process payments.

​
Next steps

  1. Run a test payment using an N-Genius test card.
  2. Verify that:
    • The payment appears in the N-Genius portal.
    • The payment status updates correctly in Payrails.
  3. Once verified in test mode, repeat the setup in live mode.
