GraphDefinition on the FHIR specification website.
A formal computable definition of a graph of resources - that is, a coherent set of resources that form a graph by following references. The Graph Definition resource defines a set and makes rules about the set.
The body should be a list of valid JSON patches for GraphDefinition. For example, to update a Slot status to busy, this would be the body:
[
{
op: 'replace',
path: '/status',
value: 'busy',
},
],
