How can I create custom criteria for feature gate targeting rules in Statsig?

Date of slack thread: 7/29/24

Anonymous: Hey folks. I’m looking for documentation on how to create custom criteria to use in my feature gate targeting rules. A Google search turns up links to FAQs that no longer exist and I’m having trouble finding it in the developer docs. Thanks in advance!

tore (Statsig): The custom condition is documented here: https://docs.statsig.com/feature-flags/conditions#custom. You can create those rules on a flag, but they depend on a key:value pair that you set in the StatsigUser object for that check - so I’m not sure if your question is about the console setup piece or the sdk check part.

Anonymous: Thanks. Can we pass in additional k/v pairs when doing a gate check as well (additional context at the call site) or does it all need to be configured on the user object?

Vineeth Madhusudanan (Statsig): It needs to be configured in the user object - but you can update the user object at anytime. If you’re doing this on a server SDK, it’s effective immediately with no round trips to Statsig. Most people build something like the viewerContext back at FB to make this simple.

We evaluated Optimizely, LaunchDarkly, Split, and Eppo, but ultimately selected Statsig due to its comprehensive end-to-end integration. We wanted a complete solution rather than a partial one, including everything from the stats engine to data ingestion.
