Java

This tutorial provides you with a step-by-step walkthrough on how to interact with the IoT Connect 365 API

This is not a production-ready application. Please take your time to make it meet your business requirements and production standards.

Steps

Step 1

Create Your Simple Flask App

keyboard_arrow_down

Before you can access the IoT Connect 365 API, you will need to get the following information:

• Application token

Enter your credentials in the app.properties file

Step 2

Get the Authentication Token

keyboard_arrow_down

Before you can use the API, you have to fetch an authentication token, by providing:

• Application Token

The authenticate() method will take the application token, which will then be sent to the /authenticate/ endpoint to generate the authentication token

Step 3

Define Controller to Select an Endpoint

keyboard_arrow_down

This Java code will display a menu to the user and prompt for a choice, showing the list of available items on which the user will perform certain actions

Step 4

Choose Action for Selected Endpoint

keyboard_arrow_down

Prompt the user for an action based on the item selected from the previous step.
