The haau3 platform API is in preview: it may change as we build, usually to add features or improve performance. Every API open to customers today is included in every plan. Free to start on the Developer plan.

Request

GET /v1/fhir/r4/Questionnaire
  ?url=<canonical-url>

Response

{
  "resourceType": "Bundle",

  "total": 1,
  "entry": [
    { "resource": {
        "resourceType": "Questionnaire",

What it does

  • Fetch a questionnaire by canonical URL, or list the curated set
  • Served exactly as published, including the copyright that must travel with the form
  • Every search parameter is either served or refused by name, never quietly ignored
  • Build the response in your own application, so answers stay where they were given
  • Standard FHIR R4 and SDC, so a form works with tools you already have

Built on

FHIR R4SDCLOINC

A curated set of health questionnaires, served as FHIR Questionnaire resources exactly as their source publishes them, down to the order of the answer options. Forms published at their own address are reached too, from places this service is set up to reach. Fetch one by its canonical URL, render it with your own components, and build a standard QuestionnaireResponse in your application. Nothing about a respondent is sent here or stored here. More instruments are coming.
