RequestGroup on the FHIR specification website.

A group of related requests that can be used to capture intended activities that have inter-dependencies such as "give this medication after that one".

The body should be a list of valid JSON patches for RequestGroup. For example, to update a Slot status to busy, this would be the body:

[
  {
    op: 'replace',
    path: '/status',
    value: 'busy',
  },
],
