4.4. Click Deploy.
4.5. Click Yes to confirm the deployment.
After the deployment, a summary of the deployment will be displayed as shown below.
You view the resources for each of the published APIs.
Note: Follow the below steps if you encounter any errors/failures when deploying your APIs.
4.6. Click Download Integration Project to download the integration project file.
Info: Click the Learn more... to learn more about the integration project and how to import projects into WSO2 Enterprise Integrator.
4.7. When you are all set, click Finish.
4.8. Click Yes on the warning pop-up.
5.1. Sign in to the developer portal and click Applications.
The applications owned or shared with you are listed in the view below.
WSO2 Open Healthcare sandbox comes with a pre-created DefaultHealthcareApp application, which allows 10 requests per minute by default.
You can also register your own SMART on FHIR® applications.
5.2. Click Applications and click Add New Application.
5.3. Enter the required application details, and click Save.
Note: There is only one throttling policy (10PerMin) enabled in the sandbox.
Once you successfully create the application, you will be redirected to the application Overview page of the application.
5.4. Click Applications to navigate to the Applications listing page.
You view your new application listed with the other applications. The application owner can edit or delete the application.
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
The sandbox supports the two options below to invoke APIs.
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.
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.
Your tenant name is the part that comes after the `@` character in your username.
For learning more, see HL7 FHIR® Capability Statements.
Info: Sample Integration project includes an application which will connect to a back-end database, which contains the sample health data. It will transform that data from the database into FHIR® format and expose the same as FHIR® APIs accordingly.
You can import the downloaded project with the WSO2 integration Studio.
8.1. Download WSO2 Integration Studio.
8.2. Navigate to the <microesb> folder.
8.3. For example, if you are using Linux, your <microesb> folder would be /IntegrationStudio/runtime/microesb.
8.4. Download the provided files and copy them into the required folder as shown below.
|Copy the FHIR® Base Bundle to <microesb>/dropins||https://dist.wso2.org/downloads/open-healthcare/sandbox/wso2-fhir-base-1.0.0.jar|
|Copy the Stax API JAR to <microesb>/wso2/lib/||https://dist.wso2.org/downloads/open-healthcare/sandbox/stax2-api-3.1.4.jar|
Note: Make sure to copy these files before starting the Integration Studio.
Now, you can run the Integration Studio and import the previously-downloaded project file into it.
8.5. Open the Integration Studio application.
8.6. To import the project, click Open Project.
8.7. Select the root directory of the downloaded Integration Project file.
8.8. Click Finish to complete importing the project.
You have successfully imported the project into the Integration Studio.
