Hi @demo91673,

Can you confirm that the meeting host has a license? This is a prerequisite for this API and will throw this kind of error if the host of the meeting to which you’re registering users is not licensed.

Let me know—thanks!
Will

Okay, But create a meeting by the host (it’s licenced)
can we add a participant to send invite links (it’s required licenced?)

@demo91673 as long as the host of the meeting to which you’re registering participants is licensed, you should be able to register any user (regardless of their license).

Thanks!
Will
