Playing with FHIR – Digital Transformation with IBM API Connect-2
7. Locate the Policy menu item on the left. Notice how the page just shows the invoke policy. When we start applying logic to the API, this screen will be updated to show visually how the flow will be executed: Figure 6.15 – Default policies for FHIR API Now that you have familiarized yourself with…

Playing with FHIR – Digital Transformation with IBM API Connect-1
Everyone has a lot of fun utilizing FHIR in puns, but when it gets down to interoperability in healthcare, utilizing FHIR APIs is just what the doctor ordered. What you will be creating is the FHIR Patient resource as an API and retrieving data from an FHIR server on the web. The endpoint you will…

FHIR server – Digital Transformation with IBM API Connect
The FHIR server is where you will initiate your API calls to begin the exchange of data. You might think of it as the repository of the resource data accessed via the APIs you create. Many of the FHIR servers are built on Java but other languages exist. There are a number of test FHIR…

Technical requirements – Digital Transformation with IBM API Connect
With this chapter, you will be referencing a number of Swagger files to assist you with the learning experience. You will find these files in GitHub using the following URL: https://github.com/PacktPublishing/Digital-Transformation-and-Modernization-with-IBM-API-Connect. You should copy the files for this chapter to your development environment. We will be utilizing the LTE and API Manager to perform the…

Testing the REST Proxy- Digital Transformation with IBM API Connect
It is time to test the REST proxy. You will use the Test tab to test the REST endpoint. The endpoint will remain the same for GET and POST method invocations: Figure 5.12 – GET request for the REST Proxy 5. You will test the POST method now. Change the Request URL to the POST…

Creating a REST proxy- Digital Transformation with IBM API Connect
Similar to the starting steps that you took while creating a SOAP proxy earlier, go ahead and start your LTE environment, open API Designer, connect to your workspace, and connect to your LTE environment. After that, follow these steps: Figure 5.10 – REST proxy to SOAP service pattern There are two main things to note.…

Testing the SOAP Proxy- Digital Transformation with IBM API Connect
There are multiple ways to test your API. You can either use the SoapUI tool or the test tool built into API Designer/API Manager. You will be using the SoapUI tool for this test. Through this test, you will explore how the API’s base path and path values are mapped to the actual URL. You…

Creating a SOAP proxy that invokes a SOAP service- Digital Transformation with IBM API Connect
Consider a scenario where you want to expose an existing SOAP service where requests from API consumers are forwarded, as-is, to that SOAP service. This pattern of API/service interaction is depicted in Figure 5.4: Figure 5.4 – API proxy/SOAP service interaction We will now explore this pattern in detail by creating a simple SOAP API…

Technical requirements- Digital Transformation with IBM API Connect
The steps discussed in this chapter are built upon the installation of the APIC Designer and APIC LTE environment covered in Chapter 4, API Creation. They also use two publicly available SOAP services: the Calculator service (used for building a SOAP API proxy) and the Account service (used for building a REST API proxy). You…

Error handling- Digital Transformation with IBM API Connect-2
Inline Referencing and GatewayScript Referencing of Parameters/Variables Techniques for accessing Parameters using Inline Referencing and Context variables are slightly different. Path, query, and header type Parameters can all be accessed using request.parameters.[parameter-name] using the Inline referencing technique. But to access Parameters in the GatewayScript Policy, you will need to use request.headers.[header-name] to access the header…
