I already know this page. But what I want to know is whether the APIs that HS opens to different partners are all the same. Because my vendor said they can't integrate with HS to this extent with Parllay.
it shouldn't consider whether the APIs that HS opens to different partners are all the same or not, it depends on how exactly the integration platform has the capabilities, because the WeChat ecosystem is with multiple other business account types, which requires strong capabilities to gather them into one place, that's actually why iParllay comes up and can do in such an extended degree.
