Please see Fullstory's developer documentation for more detailed API information:
Using Fullstory, you can see the messages in the user's browser console upon playback.
Our API provides you a way to send messages to Fullstory directly, without adding noise to the user's DevTools console.
For example, if you wanted to track the message "USER is going to /login", using the Logging API you can add this info to the Fullstory session directly and view it in the DevTools panel in playback:
Note: We officially released V2 of our Logging Browser API (e.g. log) on November 1st, 2023. If you're still using V1 of our Browser API (e.g. FS.log), please refer to our V1 API documentation found here.
If you were using Fullstory prior to August 3rd, 2023 and aren't sure which version of our Browser API is compatible with the data capture snippet deployed on your website, please refer to these instructions to confirm.
You can log messages at various levels with our API (log, info, warning, error, debug). This then allows you to search for Error Clicks and pages with large numbers of console errors or warnings:
