Basic Usage

import { Trueguard } from "@trueguard/trueguard-js";

// Initialize with your public API key

// Create a verification session
try {
    const verificationId = await trueguard.verificationSession();
    console.log("Verification ID:", verificationId);

// Use this verification ID in your backend API calls
    // to associate user actions with this fingerprint session
