Hi, now I would like to continuous on the topic that we talk about previously

Using Postman for testing the OAuth2.0 of the InterSystems FHIR repository - Part1

Question 1: Where is my client_id and client_secret come form?

Short answer: Authentication Server.

 

If you don't have an Authentication Server, you may set up one as following

 

Provide the hostname (the host must support Https), at least 1 grand type (we choose client credential here), and SSL/TSL configuration

 

Input the scopes (here we input user/*.read and user/*.write, which is based on the scope support by the FHIR server (resource server)). Just in case if there is some scope we missed, check the Allow unsupported scope.

 

JWT setting choose RS256 (this is just an example, you may choose the one that fit your architecture)

 

Change the Generate token class to %OAuth2.Server.JWT. And update the namespace if needed. 

Save the setting

Question 2: How to check out client_id and client_secret come form Authentication Server?

Short answer:  Setup an OAuth2.0 Client (if you don't have) and created a client

 

Below are the steps for setting up an OAuth 2.0 Client.

 

Click Create Server Description

 

 

Input the Issuer end point and SSL/TLS configuration here

and click Discover and Save

 

 

You can find the related information in the OAuth2.0 Server configuration page 

 

 

After the Discover and Save, you may see something similar to below. We may need to take a look at the token endpoint, which we need it for checking out a token

 

 

After the configuration above, now, it's time for us to create a client call postman 😁

Click on the OAuth 2.0 Client button

 

 

Click on the Client Configurations

 

 

Click Create Client Configuration

 

 

Input the Application name and Client name, choose the Client type confidential, input the Hostname for the Client redirect URL, choose the Required grant types Client credentials

Click Dynamic Registration and Save

 

 

You may see something similar as following.

Now, it's time to check out our client_id and client_secret😁😁

Click on the Client Credential tab

 

 

You can copy you client_id and client_secret here 😉

Question 3: How to add my FHIR server as resource server and related to Authentication Server?

Short answer:  Setup an OAuth2.0 Client (if you don't have) and create a resource server. Then apply the resource server to the FHIR server setting 

 

 

To create a resource server

 

 

Click on the Client Configurations

 

 

Click Create Client Configuration

 

 

Input the Application name and Client name, choose the Client Type Resource Server

Click Dynamic Registration and Save

 

 

Now the Resource Server is setup, then we should apply it to the FHIR server

Go to Health

 

 

Then, FHIR Server Management

 

 

Then choose the FHIR server to Edit

 

 

In the FHIR Server Authorization Setting tab, choose the OAuth Client Name from the list and Save 

 

Yeah!! I think that all we need to setup our InterSystems FHIR server with OAuth feature😁
