Additions

  • Added new nehrForm enum value to the additionalField query parameter on GET /api/v1/referrals/:referralId. When requested, the response includes:
    • nehrForm — the referral form rendered as a self-contained HTML document, suitable for forwarding to NEHR.
    • nehrFormType — a human-readable description of the NEHR form type(s), with multiple templates joined by |.

Documentation Changes

  • Added a new NEHR Integration page in the Concepts section, explaining how to map RefX fields (offering.nehrCode, offering.specialty, nehrForm, nehrFormType) into a NEHR putComposition request.

Recommendations

  • For NEHR integrations, call GET /api/v1/referrals/:referralId?additionalField=nehrForm immediately before submitting to NEHR, and forward the returned nehrForm HTML as-is — do not modify, reflow, or strip styles, or it may not render correctly in NEHR.
  • Read the new NEHR Integration concept page for the full mapping between RefX fields and NEHR putComposition payload locations.
  • If you have any questions or need support with these changes, please reach out to the RefX team at refx-support@health.gov.sg.
