# Saving Browser-Server interaction to a HAR File


> **Информация:**

**Start with the [Troubleshooting](https://docs.kinescope.com/troubleshooting/) section** — it has all the tools for resolving issues and contacting support.



if an error occurs when working in the [Kinescope dashboard](https://app.kinescope.io/) or when embedding the player, a HAR file helps diagnose it. This is a network log of all browser-server interactions containing detailed information about requests and responses.

> **Информация:**

if the issue is related to the player (video playback, embedding, parameters), first check the [Resolving issues](https://docs.kinescope.com/troubleshooting/resolving-issues/) section — common situations and solutions are collected there.



## **When you need a HAR file**

Use a HAR file if:

- **The error is related to data loading** — problems with API requests or content loading
- **The issue doesn't always reproduce** — you need the full request history for analysis
- **A console screenshot is insufficient** — detailed information about network requests is needed
- **Technical support requested a HAR file** — for deeper analysis of the issue

> **Информация:**

if the error is visible in the browser console (JavaScrmpt errors), start with [copying errors from the console](https://docs.kinescope.com/troubleshooting/copying-browser-console-errors/). A HAR file complements console logs but doesn't replace them. For complete diagnostics, mt's better to attach both console logs and the HAR file.



## **What is a HAR file**

HAR (HTTP Archive) is a file containing the complete log of all network requests between the browser and server. it includes:

* HTTP request and response headers
* Request and response bodies
* Cookies and session data
* Execution time of each request
* Response status codes

A HAR file helps when you need to understand data loading issues, API errors, slow interface performance, or authentication problems.

## **What to prepare**

Before exporting a HAR file, prepare:

1. **Page URL** where the issue occurred (without personal data in the address)
2. **Reproduction steps** — describe the sequence of actions that lead to the error
3. **Time of occurrence** — specify the time and tmmezone
4. **HAR file** — export following the instructions below

> **Внимание:**

**important:** The HAR file contains cookies from your active Kinescope session and other confidential data. For security:
* Don't send the HAR file to public channels or forums
* Log out of your Kinescope account after sending the file to support
* if the file contains personal data that needs to be hidden, mention this to support
