MQTT overview

MQTT (Message Queuing Telemetry Transport) is a messaging protocol for the Internet of Things (IoT). Its usage spans from small devices for home automation and wearables, to automating large-scale industrial machineries. It’s a lightweight technology where clients connected to a single broker can publish messages to different topics and subscribe to topics to receive messages from other connected clients. The messages are transferred with low-bandwidth usage, low-power consumption, and efficient distribution of information to one or many receivers, all adding to the popularity of MQTT.

Work with MQTT APIs using Postman

Postman provides you with a client interface to debug your MQTT-based APIs. If you haven’t already, download and install the Postman desktop app to get started.

You can do any of the following when you create a new MQTT request:

• Connect to a broker.
• Subscribe to topics.
• Publish messages.
• View messages received from the broker.

After saving your MQTT request into a collection, you can do the following:

• Reuse it later.

• Document it.

• Share it with your teammates.

• Publish it to the community on the Postman API Network.
