So I am building an online course and after someone buys the course I would like to either:
add them to a private group in Discourse if they have already registered with the same email OR
create an account for them, or send them an email to register and automatically join the group
I haven’t found a good way to do that yet! The best way I can think of is creating an invite link for that group, but that could easily be shared and the users that already registered could not use it
Any ideas? I looked into Zapier and Integromat integrations but did not see anything useful
