. As shown in the picture above: This QR code needs to be scanned by the super administrator of the merchant platform. After scanning, you will become the super administrator of the merchant platform. The super administrator is the contact person of the merchant account. He has the highest management authority of the merchant account. He will receive important notifications from the platform and can perform fund operations. Please make sure that the super administrator WeChat has successfully bound your bank card and is connected with the merchant to be bound. The real names of the contacts must be the same, otherwise the binding cannot be performed. During the registration process and when modifying information related to the merchant account in the merchant backend, you need to use the super administrator's WeChat code scanning verification and the corresponding mobile phone number verification code multiple times.
After scanning the QR code, follow the prompts to complete the merchant information. You can only fill in the required fields.
There are two types of entities here: one is individual industrial and commercial households, and the other is enterprises. When selecting an individual industrial and commercial household, the account type can be filled in as a public account or a legal person account. If you choose a company, you need to fill in the public account.
When choosing here, you can choose according to your needs. For our mini program, just select the company.
Select the mini program for the business scenario here:
directly fill in the APPID of the mini program here. Appid is the unique identifier of the mini program and can be obtained on the mini program platform.
After filling in all the above information, follow the prompts to verify the account. After the administrator scans the QR code on WeChat, he can complete the contract according to the prompts on his mobile phone.
At this point, the merchant account has been created. At this time, you can log in to the merchant platform to view the binding relationship between the merchant account and the mini program.
Of course, we can also log in to the mini program platform to view the binding relationship. Mini program homepage - "WeChat payment:"
What needs to be noted here is that the merchant name filled in when registering the merchant must be consistent with the name of the subject filled in when registering the mini program.
