This Skill guides developers in correctly identifying users in Fullstory to link sessions to stable user IDs, enabling reliable analytics, searchability, and cross-device tracking while preserving user privacy.
Identify a logged-in user and link their session: FS('setIdentity', { uid: user.id, properties: { displayName: user.name, email: user.email } })

Use setIdentity to link browser sessions to stable user identifiers by passing a uid and properties object immediately after authentication. This ensures accurate analytics and cross-device tracking while maintaining user privacy.
Use setIdentity for the initial linking of a user session to a uid, and use setProperties for updating user attributes like displayName, email, role, or plan. This distinction ensures reliable session searchability and accurate user segmentation.
Using email addresses or other PII as the uid is discouraged. To preserve user privacy, you should use a stable, internal user identifier for the uid, while passing the email as a property for discoverability and segmentation.
Apply setIdentity across login, page load, and OAuth/SSO callbacks to maintain a single identity across devices and sessions. This ensures session data remains associated with the correct uid during SPA and SSR navigation.
To anonymize users when switching accounts, use the anonymize function provided by the Skill. This breaks the link between the browser session and the previous uid, ensuring subsequent session data is not associated with the prior user.
