How to install Insomnia on Ubuntu 22.04

Insomnia is an open-source, cross-platform API client for GraphQL, REST, and gRPC. It’s a free cross-platform desktop application that takes the pain out of interacting with the designing HTTP-based APIs.

Insomnia is an API client that allows you to send requests outside your terminal without writing code. What you need to know in the API world are the requests and endpoints.

An Endpoint is a requestable URL. Think of it like this, you have a domain name and inside that domain name, there are a few routes pointers taking you to a certain page. For example, for, we have an endpoint like category/monitoring.

A Request is a structured way to communicate with an API. The request makes use of the GET, POST, PUT, PATCH, and DELETE.

  • GET: returns information from an API.
  • POST: sends data entered and returns a confirmation through an HTTP response message.
  • PUT/PATCH: Modifies a record that has been requested by the user.
  • DELETE: Removes the record from the database
