Any docs on how to create a provider facing app using Epic

[sibin c sebastian]

Hey I have been trying to build a provider app using epic couldnt find any docs on it! 

[Sean Nolan]

I have a working tutorial using almost all hand-coded Java --- it may or may not be the right architecture for your app, but it definitely will help you understand the concepts and is a useful reference as you work through your project. There are four parts --- they all apply to implementations against Epic, but about halfway through #2 is specifically where we connect to their sandbox.

Hope it helps!

hey thanks, do you have any idea about pulling data from epic ? i need to pull data for my web app from epic when a patient enrolls and gives consent.

Do you mean pulling data offline, like when the patient/provider is not actually present at a website? You’ll need at some point in the process to obtain an auth token to make FHIR requests --- this can be done by the provider or patient using a flow similar to the one in that tutorial. If you request “offline” access you’ll also get a “refresh token” that will enable to you to obtain new tokens without user interaction once the original one expires. One caveat --- I don’t know the status of Epic giving long-lived tokens these days, you may find that you’ll have to interrupt the user every once in awhile to re-obtain auth, which is a big pain. But with that token, you can just make FHIR requests as usual. There is no FHIR-based trigger to let you know when new data is available, so you’ll have to implement polling of some type.

 

There is a separate backend auth flow (https://build.fhir.org/ig/HL7/smart-app-launch/backend-services.html) --- but I don’t know what the support levels are for this in Epic, or how challenging it is to set up --- just haven’t done it.

 

Hope that at least gets you started! ---S
