Development Required Parameters
Last updated: 2025-04-22 18:11:24
Before starting development in the standard merchant mode, the following development required parameters need to be prepared:
Parameter | Description |
mchid | Merchant ID (mchid) is the unique identifier for the merchant in the superapp's payment. All payment-related API calls must include this parameter for the superapp's payment to verify the merchant's identity. This ID is provided to the merchant upon successful registration. For details, see Virtual payment-Direct Purchase of Mini Game Items. |
AppKey | It is used to sign the payment request, indicating that the request is initiated by the payment module on the developer's server. For details, refer to Payment request signature algorithm |
The superapp needs to enable the following features:
1. Enable merchants to complete the onboarding process and provide the mchid (merchant ID) to the merchant.
2. Provide a feature for merchants to set up the AppKey.
