1、API parameters

The appId of PMMax represents the system-integrated application, and the key is bound to the appId. For the ISV service provider, the system integration is performed by the ISV service provider, so the appId in the transaction interface is the appId of the ISV service provider. The actual business is generated by a specific merchant, so the merchantNo sent is the merchantNo that the merchant signed the business in PMMax and assigned.

2、Authorization relationship

When a merchant initiates a payment transaction through the platform of the ISV service provider, it needs to authorize the appId of the ISV service provider in the background of PMMax. After the authorization is completed, PMMax will allocate an auth token. ISV service providers need to send merchant_auth_token=auth token assigned by authorization in the http header when requesting a transaction
