The REST-API now includes the downtime mode in the responses of the Show all schedules downtimes and Show downtime endpoints.

The mode reflects whether the downtime is flexible. It can either be:

{"type": "fixed"}

Or, for flexible downtimes with the flex duration in minutes:

{
    "type": "flexible",
    "duration_minutes": 120
}

Flexible downtimes can already be created with the duration parameter on the Create a host/service related scheduled downtime endpoints. The behaviour there doesn't change.
