After successful installation of the module, the RESTful API is available under localhost. With the swagger user interface you go to:

http://localhost/restdoc/swagger-ui/index.html

There are Things-Search endpoint and Things endpoint. If you expand Things endpoint, the Feature endpoint is also available and you receive the information you need.

The GET request could be made not only via the Swagger UI. A simple GET request could be executed in every browser.

For example:

http://localhost/search/things

http://localhost/things?ids=gatewayId:mydevice

You should use:

• the swagger interface,
• extensions for the web browser
• a special software with REST client (like Postman)

for:

• more complex GET requests, when:
  • you want to provide some kind of headers
  • there are more parameters of the request,
• PUT and POST requests,
• event subscription.

The result of:

http://localhost/search/things

http://localhost/things?ids=gatewayId:mydevice

is in JSON format, not Java specific, so your application can be in any other language as this is REST API and can be used on different platforms. This provides flexibility.
