Overview

LianLianPay is a leading Chinese digital payment platform that provides comprehensive payment solutions for businesses, with a focus on cross-border e-commerce and international payments.

Setup

LianLianPay provides a self-service sign-up for both test and live accounts. To get started, visit the LianLianPay sign-up page and create your account.

Follow the LianLian configuration guide to collect the merchant information and RSA keys, review callback settings, and save the connection in EFundPay Dashboard.

Credentials

To configure the connection, open the LianLian Global Acquiring Dashboard and prepare:

• LianLian Merchant ID from Merchant Management → Merchant Information.
• An optional LianLian Site/Sub-merchant ID, only when it was issued by LianLian.
• The merchant's PKCS#8 RSA private key for signing requests. Register its paired merchant public key with LianLian.
• The separate LianLianPay platform public key from Developer Management → Key Configuration for verifying responses and notifications.

LianLian does not use an API Key or Webhook Secret for this EFundPay connection. See the configuration guide for the exact key roles and formats.

Webhook Configuration

EFundPay supplies the payment or refund notification_url in each request to LianLian. No fixed payment/refund webhook needs to be added in the LianLian Dashboard.

The LianLian Dashboard's Developer Management → Callback Management page contains separate card-binding and Dispute Callback settings. Configure both with their dedicated EFundPay webhook URLs. The field labelled Dispute Callback carries two distinct notification types: CHARGEBACK is a formal chargeback, while RDR is a Rapid Dispute Resolution pre-dispute alert/automatic-refund outcome. EFundPay handles them separately and never treats RDR as a formal chargeback. For the exact URLs, screenshots, and steps, see the configuration guide.

Testing

Use the LianLian sandbox merchant account, RSA keys, payment methods, and test data issued for your account. Sandbox credentials are merchant-specific; do not assume that credentials or test cards from another merchant can be reused.

Test at least payment creation, asynchronous payment status updates, refund creation, and asynchronous refund status updates before switching the EFundPay connection to production.
