When building your iAPI you will need to test it. You need to check if the responses are according the format BOA expects. The easiest way is to use an application as Postman. With this application you can start with a FREE plan. It offers a lot of functionality, and it will make it much easier to test the endpoints you need to create.
You can define the requests you want to send to your API, and you will get the responses on your screen. This way it will be rather easy to check if everything is formed as expected.
