How to generate a HAR file for Blip scenario analysis

  • Updated

Why are we asking for this? 

In some scenarios, mainly when there are intermittent errors, slowness, or unexpected behaviors on the platform, we need to analyze the communication between the browser and Blip services. The HAR (HTTP Archive) file records all requests made during the use of the application — this allows us to:

  • Identify technical failures with more precision

  • Understand if the problem is in the frontend, backend, or integration

  • Accelerate the analysis and resolution of the ticket

Without this file, our investigation may be limited.

 

Before starting

  • Ideally, generate the HAR at the exact moment the error happens

  • Avoid navigating in other tabs during collection

  • If possible, reproduce the problem only once during the recording

     

How to generate a HAR file in Google Chrome 

This is the recommended browser.

1. Access the page where the problem occurs 

Open Blip (or the screen where the error happens).

2. Open the developer tools 

You can use one of the options:

  • Right-click → Inspect

  • Or press F12

  • Or go to: Menu (⋮) → More tools → Developer tools

3. Access the "Network" tab 

In the panel that opens, click on the Network tab and select the Socket option:

4. Configure the capture 

Ensure that:

  • The recording button is red (active)

  • The "Preserve log" option is checked

  • Click on the "Clear network log" icon to clear old records 

This ensures that only the error will be captured.

5. Reproduce the problem 

Now, perform exactly the action that generates the error in Blip. Examples:

  • Send message

  • Publish flow

  • Access bot / customer service

  • Trigger integration

6. Export the HAR file 

After reproducing the problem:

  • Click on the download button;

  • Or right-click on any request and select: "Save all as HAR with content" 

The file will be saved on your computer.

7. Send the file to support 

Attach the HAR file to the ticket or send it to the responsible team.

 

Important tips

  • If the file comes back empty (0KB), repeat the process ensuring that the recording is active

  • Avoid multiple actions — the more focused, the better the analysis

  • If the problem is intermittent, it may be necessary to repeat more than once
