### Get available slots

A call to Slots is for querying a target endpoint for suitable slots to book a new Appointment into for a patient. 
A request for slots support various filter parameters but requires the service identifier, slot status(es) and a timeframe to limit the search. 

As documented in the [NHS Booking Standard](https://developer.nhs.uk/apis/uec-appointments/fs_slotmanagement.html), a receiver assigns the service identifier to groups of slots, under a schedule, which ties schedules together for a particular service.

## Query parameters

- `status` string[], required
- `start` string, datetime, required
- `Schedule.actor:HealthcareService` string
- `_include` string[], required
