GuidanceResponse on the FHIR specification website.

A guidance response is the formal response to a guidance request, including any output parameters returned by the evaluation, as well as the description of any proposed actions to be taken.

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

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