Changelog

v0.0.67 - 2026-04-29

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.

Recommendations

• Include nationality information when calling POST /api/v1/links/upsert using the provided enum values to prefill the referral form and reduce manual entry for the user.
• Use the isCancellable field in the GET /api/v1/referrals/:referralId response to determine whether to show a cancel option in the UI.
• Use the coreStatus field in the GET /api/v1/referrals/:referralId response instead of the status field to determine the status to display to the user. The status field contains more granular information that may not be relevant for display purposes.
• Do not programmatically handle the type field in the timelineEvents array in the GET /api/v1/referrals/:referralId response as there may be new event types added in the future. Instead, use the description field to display meaningful information to users without needing to update your system for new event types.
• Use the new sender-action-required enum value for the status query parameter in the GET /api/v1/institutions/:institutionIdType/:institutionId/referrals endpoint to highlight referrals that require action from the user.
• Use the new label field in the links array in the GET /api/v1/referrals/:referralId response as the text on buttons in the UI that redirect users to RefX.
• Read the new and updated documentation pages for recommendations on how to successfully integrate with RefX.
