patch https://fhir-api.zapehr.com/r4b/OrganizationAffiliation/
OrganizationAffiliation on the FHIR specification website.
Defines an affiliation/assotiation/relationship between 2 distinct oganizations, that is not a part-of relationship/sub-division relationship.
The body should be a list of valid JSON patches for OrganizationAffiliation. For example, to update a Slot status to busy, this would be the body:
[
  {
    op: 'replace',
    path: '/status',
    value: 'busy',
  },
],
