Zendesk Customer Support may occasionally need additional information about the network requests that are generated in your browser. A member of the team may ask you to record a HAR file, or a log of network requests, while that issue occurs. It's helpful to include any browser console logs in addition to a HAR file. Similarly, you may also collect Windows log files in addition to HAR files.

Instructions for generating HAR files

Click the links below to read the instructions to generate a HAR file and console logs in the browser that you use.
