Before starting development in the standard merchant mode, the following 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 Merchant Binding.
serial_no
Merchant certificate serial number.
appid
A unique identifier applied for on Super App as a Service (SAS). To use the superapp's payment feature, this ID must be bound to the merchant ID. Refer to the merchant ID binding process for details.
APIv3 key
The superapp's payment feature uses the APIv3 key to encrypt callback information. Merchants must decrypt the encrypted callback data using this key. Set up the APIv3 key before integration.
Merchant API certificate
Used to generate request signatures with the private key when initiating APIv3 requests.
Superapp's payment public key
Used to verify signatures on APIv3 responses and encrypt sensitive information (e.g., names, ID numbers) for transmission.
The superapp needs to enable the following features:
1. Enable merchants to complete the onboarding process and provide them with mchid (merchant ID), serial_no (merchant certificate serial number), and merchant API certificate.
2. Provide a feature for merchants to set up the APIv3 key.
3. Allow merchants to request and get the superapp's payment public key.
