Generating a HAR file

Last updated

When troubleshooting complex issues (e.g., store loading), Ecwid’s Customer Care Team often requires additional information to see how your store communicates with your browser.

Our team may request a HAR file (stands for HTTP Archive) or a log of network requests to investigate the issue. This way, we can check the network requests from your browser when the issue occurs. Here are instructions for generating HAR files in the most popular browsers.

If your browser isn’t listed, search for “How to generate a HAR file [your browser]” on the web.
