Easy Pay
Channel Overview
Easy Pay (易支付) refers to third-party aggregate platforms that wrap WeChat, Alipay, and other mainstream methods behind a unified protocol — low barrier and quick to onboard. DaxPay follows the Easy Pay protocol (product easy_pay); the current phase covers WeChat and Alipay QR collection.
Easy Pay is a commercial-edition extended channel, available after purchasing a commercial edition. See the channel overview. Each upstream platform has its own gateway and keys.
Supported Payment Methods
| Underlying rail | Supported methods |
|---|---|
| QR code | |
| Alipay | QR code |
Current-phase scope
H5, JSAPI, and other scenarios depend on the channel-level WeChat authorization system and are not available in the current phase; they will be added in later releases.
Configuration Structure
Merchant registration and integration configuration are separate steps:
- Create the channel merchant: Merchant Workbench → Channel Merchants → Create, pick the Easy Pay product and fill in the merchant name (registration only, no channel-side info needed);
- Configure keys (Channel Merchant Detail → Key Configuration):
| Group | Field | Notes |
|---|---|---|
| Basic | Platform gateway URL | The upstream platform's site address |
| Merchant ID | pid assigned by the upstream platform | |
| Keys | Merchant private key | PKCS#8 format, signs requests |
| Platform public key | Upstream verification key, for responses and callbacks |
Signature & Callback
- Request signing: SHA256withRSA — merchant private key signs, platform public key verifies;
- Payments have async notification callbacks; refunds do not — query the refund interface for final states.
Notes
- There is no sandbox; everything goes through the configured platform address — verify with small amounts first;
- Switching upstream platforms requires updating the gateway URL and all keys together;
- Upstream platforms vary in quality — confirm stability and settlement qualifications before production use.
