Update Registrant

Updates an existing registrant's profile data by their unique ID. Only the fields included in the request body are modified; omitted fields are left unchanged.

You can update personal details (name, email, company), registration status, package, sessions, and custom fields. Financial fields (individual_net, group_gross, payment_status, etc.) are read-only and cannot be modified through this endpoint.

Set override_capacity_errors=true to allow changes to packages or sessions that are at capacity. Without this flag, capacity-exceeded updates will return an error.
