Hello Medplum, I am currently developing and testing SMART integration while self-hosting. I am referring to this documentation. First question: When I remove the launchUri from ClientApplication, the page at http://localhost:3000/Patient/4d266f81-8915-4936-bd12-da6e8f450d1c/apps displays "No apps found. Contact your administrator." However, when I add the launchUri, the list appears. Is this the expected behavior? Second question: I want to allow a Practitioner to use SMART, but even when launchUri is present, the page at http://localhost:3000/Practitioner/4525f45a-598a-489b-b9cd-855dbda7af2d/apps does not display the list. and.. "No apps found. Contact your administrator." How can I resolve this issue? Looking forward to your guidance. Thanks!

Note, he has been trying to access the SMART by 'Provider Standalone Launch'. Referenced by http://smartdevsandbox.westus.cloudapp.azure.com:4013/?auth_error=&fhir_version_1=r4&fhir_version_2=r4&iss=&launch_prov=1&launch_url=&patient=&prov_skip_auth=1&provider=&pt_skip_auth=1&public_key=&sb=&sde=&token_lifetime=15&user_pt='

The action I wanted to perform was as follows: 1. Log in to Medplum client app A. 2. Click a button inside app A. 3. Redirect to Medplum client apps B or C. 4. Run Medplum client apps B or C without requiring an additional login. I spent time customizing based on this example ( https://github.com/medplum/medplum/tree/rahul-smart-on-fhir-example ), but after launching the SMART app, it didn't automatically maintain the login state, and I had to log in to Medplum again. Could it be that I don't fully understand SMART on FHIR? Would SSO be necessary for this kind of functionality?

Hi @two4zero_63114 , I'll try my best to answer these in sequence 🙂 > When I remove the launchUri from ClientApplication, the page at http://localhost:3000/Patient/4d266f81-8915-4936-bd12-da6e8f450d1c/apps displays "No apps found.

In truth, the Medplum App is meant to be a console for developers, rather than an EMR. However, it can be used to simulate the EHR launch flow. Our lightweight simulation logic is to list all

ClientApplications

that have a

launchUri

as a way of determining all the SMART-on-FHIR apps

@rahul1 Thank you for your response. Also, thanks to rahul-smart-on-fhir-example. I performed the test using commit 84acce. with

prompt=none

And... I think my question was a bit unclear. I wanted the B app, running from A while logged in, to be in a logged-in state without requiring any login at all. Additionally, I am now trying to test token-exchange in the B app using A's Medplum access token. Is this the correct approach?
