Lite SDK (Enrollment)

The Lite SDK provides full control over your payment experience. It allows you to:

Control the payment methods displayed to your customers.
Enroll new payment methods to the customer’s account.

This page focuses on the enrollment process. For details on the payment process, refer to Lite SDK (Payment).

If you wish to save cards during the payment, you can do so while the customer pays. For more information, see Lite SDK (Payment).

Enrollment workflow

The following diagram describes the complete enrollment workflow. Each step is explained in detail below:

SDK Lite Enrollment Flow

This diagram illustrates the payment method enrollment process using the SDK Lite, detailing the interactions between the Merchant Client, Merchant Server, Yuno Server, and Yuno SDK. It outlines the steps for adding a payment method and initiating its enrollment, through to receiving the final enrollment result.

Merchant Client

The Merchant Client represents your frontend application that interacts with both your backend server and the Yuno SDK. It handles the user-facing aspects of the enrollment flow, including:

Add payment method
Display payment methods to enroll
User selects payment method to enroll
Initiate enrollment
Initiate SDK to continue enrollment

Merchant Server

The Merchant Server represents your backend application that handles server-side operations and communicates with Yuno's servers. Its key responsibilities include:

Create Customer
Create customer session
Request available payment methods to enroll
Create enrollment
Receive enrollment result via webhook

Yuno Server

The Yuno Server handles all backend operations related to customer management, enrollment sessions, and payment method processing. Its main responsibilities include:

Creates Customer
Creates customer session
Returns available payment method
Creates enrollment in the payment provider
Receive enrollment results from payment provider

Yuno SDK

The Yuno SDK handles the user interface and enrollment flow on the client side, managing payment method selection and enrollment completion. Its key responsibilities include:

Continue enrollment flow
Shows screens for the user to complete enrollment
Display enrollment result (optional)
