TerminologyCapabilities on the FHIR specification website.

A TerminologyCapabilities resource documents a set of capabilities (behaviors) of a FHIR Terminology Server that may be used as a statement of actual server functionality or a statement of required or desired server implementation.

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

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