MQTT REST API Documentation

 

Introduction

While building an IoT application, there is a need to control and manage the edge devices from the manager application. So, the Bevywise MQTT Route provides a REST API to integrate MQTT Broker. This API will help you control your edge devices via the REST API. You can send messages, add new authentication keys, get client details, and do more via the API. This documentation provides a complete guide for the developers to build IoT applications using the RESTful API of MQTT Broker.

Basics

For Post

Set raw data in body.

All the parameter fields should be given as a parameter.

Once the authentication credentials you enter are verified, you will receives response. Then  create authorization and set bearer token. And for all APIs except login API, it is necessary to set authorization.

For GET

GET Method sends request to the server to collect data.

Set key and value in header type.

Set content-type and authorization in key field.

Set the value for content-type as application/json and the bearer token value.

Log-in API

This MQTT Rest API helps you login to MQTT broker user interface by using username and password in “broker.conf” file.

Method:

Post:

 http://(Server-IP):8080/api/login

Parameters:

 

PARAMETER VALUE DETAILS
username Username in broker.conf file.
password Password in broker.conf file.

Response:

On Success:

 {
    "access_token": "< token >",

On Failure:

{
    "status":"Invalid Login"

  '(Parameter Name) parameter is missing -'

Authorization Header

Authorization header is the method of providing authentication information. All the APIs below are accessing data specific to a user who logged-in to the MQTT broker. So, we need to do the session token to all the APIs. The Session token should be set as part of the Request Header to provide authentication information. The format of the Authorization header is

   Authorization: < access_token >

Error Responses On using Authorization Header:

 If Authorization header is not defined

   {
  "detail": "Authentication credentials were not provided."
  }

  If Token is Invalid
  {
  "detail": "Invalid token."
  }
