YeePay
Channel Overview
YeePay (易宝) is an aggregated payment channel on the YOP open platform. DaxPay integrates via the YOP API (product yee_pay). Its signature capability is aggregate QR — a generic QR code returned without specifying the underlying rail, auto-identified as WeChat or Alipay when scanned; per-channel orders are also supported.
YeePay is a commercial-edition extended channel; after purchasing the flagship edition the official team assists with onboarding and integration. See the channel overview.

Configuration Structure
The YeePay merchant numbers are registered when creating the channel merchant; keys are configured per channel merchant:
- Create the channel merchant: Merchant Workbench → Channel Merchants → Create, pick the YeePay product and fill in merchant name + YeePay merchant number + YeePay ISV number (parentMerchantNo; both are immutable after creation);
- Configure keys (Channel Merchant Detail → Key Configuration):
| Field | Notes |
|---|---|
| Environment | Production / sandbox |
| Channel app AppKey | YOP application identifier |
| Merchant RSA private key | PEM (PKCS#8), signs via the YOP SDK |
| YeePay platform public key | PEM format, for verification |
| WeChat AppId / AppSecret | Optional; for WeChat H5 / JSAPI scenarios |
Signature & Callback
- Request signing: RSA2048 digital envelope — signing and verification are handled automatically by the YOP SDK;
- Async notifications are form-posted (encrypted payloads) and processed after platform decryption and verification.
Notes
- The merchant number and ISV number cannot be changed after creation — confirm both with YeePay before entry;
- WeChat scenarios need the additional WeChat app configuration (AppId / AppSecret).
