Audit requirements for PDS FHIR Clients

Are there formal audit requirements for PDS FHIR client systems?

Previous APIs (HL7v3, SMSP) bear explicit requirements for the audit trail to be maintained by the client system accessing the API, but I’ve not found any such requirements in the onboarding questions for PDS FHIR. This leads to 2 questions:

  1. Are there formal audit requirements placed on the client systems accessing the PDS FHIR API and;
  2. If there are, where are they documented, and which part of the onboarding process assesses conformance with them?

Many Thanks.
