API wrappers for Langgraph Platform, to enable easy SDK access and Microsoft Graph API authorisation

[RobertNewton-Nomura]

Does anyone know if it is possible to host a FastAPI or equivalent wrapper on the Langgraph Platform, as well as the app?

I'm struggling to figure out how to interact with my hosted app through the Langgraph SDK without creating additional middleware hosted on a different service.

My aim is to link into the Microsoft graph API but the response it sends with the auth code requires a redirect URI and the API URL for apps hosted on Langgraph Platform require the use of the API key, which Microsoft can't return in their response.

Any suggestions would be much appreciated!
