Detailed description of parameters of the payment Development Account System and detailed description of account parameters

The merchant submits the application materials and bank account information on the public platform. After the materials are approved and signed, the merchant can obtain the account shown in Table 6-4 (including the relevant payment fund account of caifu Tong) for public account payment.

Account and role:

AppId: the unique identifier of a public account. After the application is approved, view it in the sent email.

AppSecret: The Key used for encryption in the public account payment request. It can verify the unique identity of the merchant. The PaySignKey corresponds to the appKey value in the payment scenario. After the application is approved, view it in the sent email.

PaySignKey, then call the API. After the application is approved, view it in the sent email.

PartnerId: the ID of a tenpay merchant. After the application is approved, check the email sent by caifu.

PartnerKey: The accesskey of caifu Tong's merchant permission. After the application is approved, check the email sent by caifu.

AppSecret, paySignKey, and partnerKey are the unique security identifiers used to verify the uniqueness of a merchant. They must be kept properly. The difference between appSecret and paySignKey can be considered as follows: appSecret is the login password used by the API and will be transmitted in the network; the paySignKey is the key used for encryption and authentication during all payment-related data transmission. It is only retained on the third-party backend and will not be transmitted on the network, and paySignKey is only used for payment requests.

The above is a detailed explanation of the parameters of the payment Development Account System, hoping to help you.
