Steps
Obtain the webinarKey for the target webinar (from the create-webinar response or a list call).
POST to https://api.getgo.com/G2W/rest/v2/organizers/{organizerKey}/webinars/{webinarKey}/registrants with at minimum firstName, lastName, and email.
Optionally include custom-question responses plus fields like organization, jobTitle, and industry supported by GoToWebinar's registration form.
Use the corresponding list-registrants call, scoped by webinarKey, to retrieve registration details for everyone registered.
Track the registrantKey returned in the response for later lookups or resending a join link.
Known gotchas
Registering someone via the API doesn't automatically resend confirmation emails unless the account's registration-email setting is enabled.
Field names differ from the GoTo Meeting/GoTo Training APIs even though auth and organizerKey concepts are shared — don't reuse a payload shape from another GoTo product.
