User Information

Tells Lucia who a visitor is once you know — usually right after they sign up or log in. Every earlier visit, click, and device from that person then joins one customer profile, so their conversion is credited to the campaign that first brought them in.

LuciaSDK.userInfo(user: string, userInfo: object): Promise<void>

Argument	What to pass
user	A stable identifier: email, your user ID, or a wallet address.
userInfo	Any profile fields you want attached (name, plan, etc.).

Example

LuciaSDK.userInfo('jane@example.com', {
  first_name: 'Jane',
  plan: 'pro',
});

Tips

• Call it as soon as you know who the user is — on signup and on every login.
• Use the same identifier every time, so visits on different devices match up.
• For web3 users, also call sendWalletInfo so the wallet joins the same profile.
