Hi,
This has been bought up before, and @tommy provided a working solution.
After creating the meeting, please try using the update meeting endpoint and setting the "registrants_confirmation_email" to false .
Original post: Registrants_email_notification seems to have no effect
Although it’s not the best solution, it has worked for me. The create endpoint could do with fixing at some point @tommy, since this temporary fix adds an extra request to each operation.
Thanks,
Alex
