Setting Server Domain Name | Weixin public doc

# Setting Server Domain Name

The server domain name of a Mini Program authorized to a third-party platform must be that of the third-party platform. After the code of the Mini Program is released via the third-party platform, the original server domain name configured for the Mini Program is deleted, and only the server domain name of the third-party platform is retained. Therefore, before releasing the code for the Mini Program, the third-party platform needs to add the server domain name of the third-party platform to the Mini Program by calling this API.

Note: This API can be called only after the domain name is registered as the Mini Program server domain name of the third-party platform.
