Mandatory fields in Add a webinar registrant service

Hello,

Why in the documentation only appear as mandatory fields ** first_name** and ** email**, and then when you call to the service it also forces you to send the fields ** last_name** and ** country** to add a webinar registrant?

Add a webinar registrant

Regards,

Hi @aitor.garcia , was this webinar created with a specific webinar template that mandates those fields?
