NuPay-Recurrent Integration Guide | EBANX Developers Academy

Nupay Recurrent allows merchants to set up and manage recurring payments through the EBANX API. This feature ensures that customers authorize merchants to process recurring payments without requiring repeated manual approvals. Whether for subscriptions or one-click payments, Nupay Recurrent simplifies the payment experience while providing robust authorization workflows.

Requirements

API credentials - Ensure you have your EBANX integration key. If not, complete the Merchant Signup Form.

How it works

Enrollment - Customers authorize recurring payments through an app-to-app or web-to-app flow. This step ensures that merchants can process future transactions seamlessly. The enrollment process has two different user experiences depending on where the customer is coming from:
- App-to-App: Ideal for purchases made within your mobile application. The customer is redirected from your app to the Nubank app to grant authorization and then returns.
- Web-to-App: Ideal for purchases made on a website (desktop or mobile). The customer receives a push notification on their phone to approve the authorization in the Nubank app.
First payment - Customers authorize the initial payment via the NuPay platform, choosing a payment source (credit or debit).
Subsequent payments - Once enrolled, future payments occur automatically using the merchant_enrollment_code, without requiring additional customer action.
Notifications - EBANX notifies merchants of payment status updates via webhooks.

Instructions

Follow the steps below.

Select your environment
Select the appropriate environment for your integration. Use the sandbox environment for testing, or the production environment for live transactions. Use the URL for your HTTP requests based on your selection.

https://sandbox.ebanx.com/ws/userenrollment/nupay

Define your parameters

You must enroll the customer in Nupay Recurrent using the /ws/userenrollment/nupay endpoint.

You can send both parameters (email and phone_number), or just one of them.

Parameter	Description
`integration_key`	Your EBANX integration key.	Required
`operation`	Set to `enrollment`.	Required
`payment_type_code`	Set to `nupay-recurrent`.	Required

Enrollment request

The enrollment step is essential for registering customers for automatic payments. This process is handled through the /ws/userenrollment/nupay endpoint.

        }
    }}

}

Sandbox Behavior - When working in a sandbox environment, the redirect_url will lead to a sandbox interface where you can simulate customer acceptance or cancellation of the enrollment agreement.

See example below.

Enrollment status check

Monitor payment for status changes
Notifications
- Once the payment is confirmed, EBANX will send a notification to the notification_url sent with your payment request, or the one stored in your EBANX Dashboard.
- Make sure your system is set up to receive notifications from EBANX for any changes in payment status.
- Learn more about Payment Notifications
Status
- After receiving a notification that status has changed, retrieve the payment status.
- When a payment is confirmed, the status will change from pending (PE) to confirmed (CO). If the customer does not complete the payment, the status will eventually change to cancelled (CA).
