This article explains how to capture a HAR (HTTP Archive) file using Google Chrome. HAR files record a browser’s network activity and are often required by Aircall Support to diagnose performance or connectivity issues.

Important: This guide is intended for technical audiences, such as IT administrators.

What is a HAR file

A HAR file captures detailed information about how your browser interacts with a website, including requests, responses, and timing data. This information helps identify network-related issues affecting Aircall.

Capture a HAR file in Google Chrome

Follow the steps below to generate a HAR file.

Steps:

  1. Open Google Chrome. Chrome is recommended for best compatibility.
  2. Open Developer Tools:
    • Right-click anywhere on the page and select Inspect, or
