Client application registration for Azure API for FHIR

In the previous tutorial, you deployed and set up your Azure API for FHIR®. Now that you have your Azure API for FHIR setup, we register a public client application. You can read through the full register a public client app how-to guide for more details or troubleshooting. We call out the major steps in this tutorial.

1. Navigate to Microsoft Entra ID

2. Select App Registration --> New Registration

3. Name your application

4. Select Public client/native (mobile & desktop) and set the redirect URI to https://www.getpostman.com/oauth2/callback.

   

Client application settings

Once your client application is registered, copy the Application (client) ID and the Tenant ID from the Overview Page. You’ll need these two values later when accessing the client.

Connect with web app

If you’ve written your web app to connect with the Azure API for FHIR, you also need to set the correct authentication options.

1. In the left menu, under Manage, select Authentication.

2. To add a new platform configuration, select Web.

3. Set up the redirect URI in preparation for when you create your web application. To do this, add https://\<WEB-APP-NAME>.azurewebsites.net to the redirect URI list. If you choose a different name during the step where you write your web app, you’ll need to come back and update this.

4. Select the Access Token and ID token check boxes.

   

Add API permissions

Now that you have set up the correct authentication, set the API permissions.

1. Select API permissions and select Add a permission.
2. Under APIs my organization uses, search for Azure Health Data Services.
3. Select user_impersonation and select add permissions.

Next Steps

You now have a public client application. In the next tutorial, we’ll walk through testing and gaining access to this application through Postman.
