Hi there, we are evalauting growthbook. Has anyone used it with Varnish, yet? In order to maintain caching, we would need an API call that for every user individually returns which features / experiment variations are enabled / disabled. I did not find this in the API docs. Is there such call? Thanks for your help

you can set up GrowthBook that way

Thanks for the explanation. Remote Evaluation does not result in all flags being returned for a single call either, does it? Because we would need the entirety of applicable flags with their configured values as one string to use that as a cache key

No, Remote Evaluation in GrowthBook does not result in all flags being returned for a single call. Instead, a new evaluation API call is made any time a user attribute or other dependency changes. You can limit these API calls to specific attribute changes by setting the ​`cacheKeyAttributes`​ property, which is an array of attribute names that, when changed, trigger a new evaluation call.
