Web APIs are the future of integration in healthcare, but creating a high quality API is difficult!
The API Designer is a cloud-based tool that makes it easier to use RESTful APIs in Iguana. The API Designer enables Iguana users to create and share intuitive APIs for web integration.
You can find the API designer here: https://designer.interfaceware.com/
The API designer was created to make it easier for our customers to build new RESTful APIs from scratch, and to leverage existing APIs from within Iguana.
The API designer also supports FHIR, see the shared FHIR API that we created.
What is it for?
The tool provides a GUI to build up a detailed definition of a RESTful API in a JSON grammar format.
The JSON grammar can be used to:
- To build a RESTful web API using the Iguana Translator
- To build an adapter to an existing RESTful web based API
Who is it for?
Anyone wanting to create a RESTful API, you will need some knowledge of:
- What web services are
- Concepts like HTTP, JSON and RESTful API
Why is helpful?
The API Designer, together with our API framework, greatly reduces the time and effort to create or document an API. It is much more productive than alternative technology choices — definitely much easier than hand-coding an API in JSON.
Three Scenarios [top]
There are three scenarios for using the API Designer:
- API Server and Client: Generate both the Server and Client using the Designer:
- Standalone API Server: Generate only the Server and use REST calls from a third party tool:
- Standalone API Client: Generate only the Client that makes calls to a third party RESTful API:
Other Benefits [top]
A high quality API needs the following:
- Good documentation: Many companies have trouble keeping documentation for their APIs up to date with the actual functionality.
- Consistency: Because most web APIs are programmed by hand by different developers over time many APIs get to be inconsistent in the language and conventions they use.
- Error Handling: A good quality API checks its inputs, and returns helpful error messages when a software client makes a mistake in how it is calling the API.
- Ease of use: It should be simple to call the API without requiring specialized tools to invoke the API. RESTful interfaces have become more popular than older SOAP based interfaces because they do not require special libraries to invoke them.
- Modern JSON based: Today’s modern developers expect APIs to use JSON – this is the easiest most widely adopted standard data format.
The API designer makes it much easier to meet these goals.
