|/smart/app||the app (also the redirect_uri after authz)|
|/smart/launch||the launch url|
|/smart/cfg||configure client ID and scopes|
OAuth2 client IDs and scopes for different FHIR servers must be stored in the /cfg section, so the SMART app can be used with multiple FHIR server implementations.
Each entry under
scopes should be a unique substring within
the FHIR server URL (for example,
epic), with the value being the
associated client ID to use or OAuth2 scopes to request.
Errors encountered during launch are probably associated with improper configuration of the client ID and scopes.
