Anonymous: Can I pass the stableId generated in the client SDK to my backend so I can use that for checking experiments in the backend? How can I access it? Is it better to use that stableID or generate one?

Statbot: Yes, you can pass the stableID generated in the client SDK to your backend to use for checking experiments. To access the stableID in the client SDK, you can use the Statsig.getStableID() function. Here’s how you can retrieve it:

const stableID = Statsig.getStableID();

As for whether it’s better to use the stableID generated by Statsig or to generate your own, the documentation suggests that if you have your own form of stableID and would prefer to use it instead of the Statsig generated ID, you can override it through StatsigOptions when initializing the SDK:

const opts: StatsigOptions = { overrideStableID: "my_stable_id" };
await Statsig.initialize("client-xyx", null, opts);

Using the stableID generated by Statsig is a good default choice, especially for device-level experiments or when other user identifiable information is unavailable (e.g., logged-out users). However, if you have a specific reason to use your own identifier that aligns better with your system’s design or requirements, you can choose to override it as shown above [source].
