Hi @Massim,
Thank you for reaching out about this. I’m afraid we don’t currently offer any alternatives for this from the API side of things, aside from requiring registration and considering adding registrants programmatically via Add Meeting Registrant API.
This API returns a unique join_url for each registrant/participant, which contains/can pass some of the same information to the Zoom Client.
This would be the closest supported way to handle this.
Thank you,
Will
