although I thought that I had seen somewhere in the forums that using an API to sign new members up was “a bad thing”. But I can’t remember why!
The reason was likely related to user privacy. Perhaps incorporate something in the third-party CMS’s terms of use so that at least users will be made aware of what will happen. But, that’s a business decision you’ll need to make.
Take a look here. You should be able to see how BuddyPress registers users by looking at the bp_core_screen_signup() function.
Hope this helps 🙂
