Create a Cal.com team event type via API v2 with an explicit scheduling assignment scheme — collective, roundRobin, or managed — and assign hosts.

Documented steps

1. Set Authorization: 'Bearer <cal_api_key>' and Content-Type: application/json.
2. Determine the target teamId (e.g. from GET https://api.cal.com/v2/teams) and the userIds of intended hosts.
3. POST https://api.cal.com/v2/teams/{teamId}/event-types with required body fields title (string), slug (string), lengthInMinutes (number), and schedulingType — exactly 'collective', 'roundRobin', or 'managed'.
4. For roundRobin, include hosts: [{"userId":<number>,"mandatory":<boolean>,"priority":"lowest"|"low"|"medium"|"high"|"highest"}]; mandatory:true marks a fixed must-attend host.
5. For collective or managed, pass hosts and/or set assignAllTeamMembers:true to auto-assign all current and future team members instead of listing userIds.
6. Optionally set lengthInMinutesOptions, description, locations, bookingFields, minimumBookingNotice, beforeEventBuffer/afterEventBuffer, disableGuests, seats, bookingWindow, or confirmationPolicy.
7. Confirm the 201 response: data.id, data.schedulingType matching your request, data.hosts, data.teamId, and data.bookingUrl in the form https://cal.com/team/{teamSlug}/{eventSlug}.
8. If using an OAuth access token, confirm the TEAM_EVENT_TYPE_WRITE scope is granted, or expect 403.
9. Expect 404 for a non-existent teamId and 400 for a malformed body such as wrong schedulingType casing.
