Cardholder Account Management Service For TR App

Account Service Merchant Acquirer Mobile Payment Internet Payment

UnionPay Cardholder Account Management Service (CAMS in short) provides a convenient way for cardholders to distribute and manage their payment credentials.

Sandbox Testing

API Introduction

What is it?

Cardholders do not need to link cards on the digital wallet or on-line (Card-On-File) merchants. Based on Token technology, under the premise of ensuring cardholders' information security, token will be pushed to these merchants and be managed direclty in Issuer App, greatly improving cardholder's payment experience. The functions mainly include: (1) Token Request; (2) Token Lifecycle Management.

Key Features

• Simplify binding card by initiating this process from issuers' App

• Avoid card information exposure and keep account confidential

• Encourage payment participation by extensive and convenient access to more third party Apps

When to Use it?

Applicable to Token Requestors who want to integrate UPI Cardholder Account Management Service and provide account management service to their customers.

Who Use it?

Acquirer, Merchant and Technical Service Provider

Where to Use it?

This API is available globally except for mainland China.

Things to Know

1. The App or website shall be provided by issuer for cardholders to initiate the token push and management.
2. Token Requestor (TR) indicates the party which stores the cardholder's token and initiates transaction with cardholder's token, such as e-wallet。
3. There are typically two types of TR, digital wallet and online merchant. The former one connects to UnionPay Mobile Payment System (UMPS), the latter one connects to UnionPay Online Payment Platform (UPOP).
4. UPI CAMS supports 3 scenarios of Issuer-TR interaction: App to App, App to Web, Web to Web. All these 3 scenarios are realized through URI method. When issuer gets the TR list from UnionPay, each TR will have 3 URI address, for iOS, Android and Web respectively. The url scheme shall be complex enough to avoid confliction with other App.
5. To ensure use experience, UnionPay recommends Issuer App to skip android/iOS scheme address first. Skip to website url happens only if the TR App is not installed on the device.
6. Sensitive information (such as Primary Account Number, PAN) is required to encrypt before transmitting it in the message.

Flow Chart

1. Cardholder select token requestor or merchant

2. Issuer send token push provisioning to TR

3. TR send token request with authorization to UPI

4. UPI respond token

5. UPI return token creation notification to issuer
