6. Invoking APIs

When you sign in to the API Developer Portal as an application owner/developer, you view the published APIs on the Developer Portal. It allows you to discover and invoke the required APIs.

6.1. Sign in to the Developer Portal and click on an API you wish to invoke.

6.2. Scroll down the Overview page of the API and click Subscribe to subscribe to the API using an application and an available throttling policy.

6.3. Select an application and an available throttling policy, and click Subscribe.

You view all the subscriptions under the Subscriptions tab.

6.4. Click Applications

• Click on the application that you used to subscribe to the API.
• Click Production Keys.
• Click Generate Keys to generate a production key.

The sandbox supports the two options below to invoke APIs.

• Invoking an API using the Integrated API Console.
• Invoking an API using an API Client.

Option 1: Invoking an API Using the Integrated API Console

6.5. Click APIs, and click on the API that you need to invoke.

6.6. Click Test under the resources section of the API.

6.7. On the API Console, click Get Test Key to add the access token in the Authorization field to test your API.

6.8. Expand the resource method (e.g., GET method), click Try it out, and then click Execute.

Now, you view the success response for the API invocation on the console.

Option 2: Invoking an API Using an API Client

Follow the [steps 6.1 - 6.4] to successfully subscribe to an application and generate production keys for the same.

6.9. Copy the access token to the [clipboard you generated].

6.10. Click APIs and then click the API you want to invoke.

6.11. Click the “Overview tab and under the ​Gateway Environments section​, and expand ​Production and Sandbox​ to retrieve the API’s base URL.

6.12. Use your preferred API client and invoke the API.

For example, if you use Postman, you can do it as shown below.

7. Invoking the Capability Statement and Well-Known Uniform Resource Identifiers

Capability statements are auto-generated based on the deployed FHIR® APIs.

The below are the open URLs (no authentication is required) for the statements. The following URL format has to be used to generate the capability statement.

• Well-Known Uniform Resource Identifiers - https://fhir.sandbox-healthcare.wso2.com/gw/t/<tenant>/.well-known/smart-configuration
• Capability Statement - https://fhir.sandbox-healthcare.wso2.com/gw/t/<tenant>/metadata

Your tenant name is the part that comes after the `@` character in your username.

Example Statements:

https://fhir.sandbox-healthcare.wso2.com/gw/t/wso2.org/.well-known/smart-configuration

https://fhir.sandbox-healthcare.wso2.com/gw/t/wso2.org/metadata

For learning more, see HL7 FHIR® Capability Statements.
