Add Webinar Registrant is not saving additional information beyond Name & Email

API and Webhooks
10

Hi @Ryan_Chapman,

I heard back from our developers.

If you need to add any additional fields except for name and email to the add registrants API, you must first make a call to Update a webinar’s registration fields and questions API.
Then with questions field of that API, you need to add these additional fields.
Once they have been added, you can call the Add webinar Registrants API, and then pass these fields.

Please let me know if you have any other questions.

Thanks
