I'm stuck while working on smart on FHR. how I will be able to Authorize through my code, currently I'm testing my Authorization and sandbox using the Launch Button. here is an example ScreenShot
I just want to know which values should I pass to authorize as I authorize clicking after Launch Button.
You have to pass the "iss" and "launch" parameters when the launch button is clicked. Please see the specification for more details. https://www.hl7.org/fhir/smart-app-launch/app-launch.html
