FEATURE FLAGS SETUP

Is providing a userID necessary when using the checkGate function with an email?

When utilizing the checkGate function within Statsig, it is imperative to provide a userID or a customID. This identifier is crucial as it ensures a consistent experience for each user. An ID matching the ID type of the gate is mandatory. It will ensure uniformity in the user experience and allows for partial rollouts to evenly split users.

It is important to note that even if an email is provided as a top-level field on StatsigUser, it does not substitute the requirement for an ID. In instances where there is no logged-in user, a stable identifier should be established, which could be stored as a cookie or in local storage, and used consistently with each call to Statsig.

At Notion, we're continuously learning what our users value and want every team to run experiments to learn more. It’s also critical to maintain speed as a habit. Statsig's experimentation platform enables both this speed and learning for us.

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.
