SMART App Launch
2.0.0 - Standard for Trial Use

This page is part of the Smart App Launch Implementation Guide (v2.0.0: STU 2) based on FHIR R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions

Example App Launch for Public Client

Launch App

This is a user-driven step triggering the subsequent workflow.

In this example, the launch is initiated against a FHIR server with a base URL of:

https://smart.argo.run/v/r4/sim/eyJtIjoiMSIsImsiOiIxIiwiaSI6IjEiLCJqIjoiMSIsImIiOiI4N2EzMzlkMC04Y2FlLTQxOGUtODljNy04NjUxZTZhYWIzYzYifQ/fhir

… and the app’s redirect URL has been registered as:

https://sharp-lake-word.glitch.me/graph.html

… and the app has been registered as a public client, assigned a client_id of:

demo_app_whatever

Obtain authorization code

Generate a PKCE code challenge and verifier, then redirect browser to the authorize_endpoint from the discovery response (newlines added for clarity):
