Hi Filip, yes we have. Works great and I can defenitely recommend to make that integration with Clarity in your experiments.
There are multiple ways to go about it but I guess it depends on your setup.
So basically you add custom tags to your experiment code. These tags can then be found in Clarity when your visitors enter your experiment.
https://learn.microsoft.com/en-us/clarity/setup-and-installation/clarity-api#add-custom-tags
If you follow that link you will see examples to setup custom tagging. You can add this in your experiment in growthbook in i.e. the visual editor in the JS code field.
Note: clarity must be loaded before your experiment runs…. usually GB is faster then Clarity so you also need to add some logic so that the custom tags are set when Clarity is loaded.
