SubscriptionStatus on the FHIR specification website.
The SubscriptionStatus resource describes the state of a Subscription during notifications.
The body should be a list of valid JSON patches for SubscriptionStatus. For example, to update a Slot status to busy, this would be the body:
[
{
op: 'replace',
path: '/status',
value: 'busy',
},
],
