    SiteAssist("changeTheme", currentTheme);
  });
</script>

`track` (Coming Soon)

Track custom events and analytics.

Signature:

SiteAssist("track", eventName: string, data?: any): void

Status: This feature is currently in development and will be available soon.

Planned usage:

// Once available, you'll be able to track events like this:

// Track a simple event
SiteAssist("track", "button_clicked");

// Track with additional data
SiteAssist("track", "product_viewed", {
  productId: "12345",
  productName: "Premium Widget",
  price: 99.99,
});

// E-commerce tracking
SiteAssist("track", "add_to_cart", {
  productId: "123",
  quantity: 1,
});

SiteAssist("track", "purchase_completed", {
  orderId: "ORD-123",
  total: 199.99,
});

`identify` (Coming Soon)

Identify users with additional information.

Signature:

SiteAssist("identify", user: {
  externalId?: string;
  email?: string;
  name?: string;
  attributes?: Record<string, string>;
}): void

Status: This feature is currently in development and will be available soon.

Planned usage:

// Once available, you'll be able to identify users like this:
SiteAssist("identify", {
  externalId: "user_123",
  email: "user@example.com",
  name: "John Doe",
  attributes: {
    plan: "premium",
    signupDate: "2024-01-15",
  },
});

Queuing Commands

The SiteAssist API supports command queuing, which means you can call API methods before the widget script has fully loaded. Commands will be executed in order once the script is ready.

Example:

// These commands will be queued and executed when ready
SiteAssist("init", { apiKey: "YOUR_API_KEY" });
SiteAssist("open");

This is handled automatically by the loader script:

!(function (t, e, c, n, s) {
  if (t[s]) return;
  const i = (t[s] = function () {
    i._q.push(arguments);
  });
  i._q = [];
  // ... loads actual script
})(window, document, 0, 0, "SiteAssist");

Custom Events

The widget dispatches custom events that you can listen to:

// Listen for custom widget events
window.addEventListener("sa:event_name", (event) => {
  console.log("Widget event:", event.detail);
});

Available Events:

Events are prefixed with sa: and include any custom events dispatched from the widget.

Example - Listen for custom events:

// Listen for all widget events
window.addEventListener("sa:chat_opened", () => {
  console.log("User opened the chat");
});

window.addEventListener("sa:message_sent", (event) => {
  console.log("User sent a message:", event.detail);
});

TypeScript Support

For TypeScript projects, you can add type definitions:

declare global {
  interface Window {
    SiteAssist: {
      (
        cmd: "init",
        opts: {
          apiKey: string;
          type?: "floating-bubble" | "sidepanel";
          theme?: "light" | "dark" | "auto";
          contentSelector?: boolean | string;
          externalId?: string;
          appContainerSelector?: string;
          widgetUrl?: string;
          apiUrl?: string;
        },
      ): void;
      (cmd: "open"): void;
      (cmd: "close"): void;
      (cmd: "toggle"): void;
      (cmd: "changeTheme", theme: "light" | "dark" | "auto"): void;
    };
  }
}

Usage:

// Now you get autocomplete and type checking
window.SiteAssist("init", {
  apiKey: "pk_live_abc123",
  theme: "dark", // TypeScript will validate this
});

// Open the widget
window.SiteAssist("open");

// Change theme
window.SiteAssist("changeTheme", "light");

Complete API Example

Here’s a comprehensive example using multiple API methods:

// Initialize the widget
SiteAssist("init", {
  apiKey: "pk_live_abc123",
  type: "floating-bubble",
  theme: "auto",
});

// Auto-open after 10 seconds for first-time visitors
if (!localStorage.getItem("siteassist_visited")) {
  setTimeout(() => {
    SiteAssist("open");
  }, 10000);

  localStorage.setItem("siteassist_visited", "true");
}

// Sync theme with site theme switcher
document.getElementById("site-theme-toggle").addEventListener("click", (e) => {
  const newTheme = e.target.dataset.theme;
  SiteAssist("changeTheme", newTheme);
});

// Add custom help button
document.getElementById("help-button").addEventListener("click", () => {
  SiteAssist("open");
});

// Keyboard shortcut (Ctrl/Cmd + K)
document.addEventListener("keydown", (e) => {
  if ((e.ctrlKey || e.metaKey) && e.key === "k") {
    e.preventDefault();
    SiteAssist("toggle");
  }
});

Best Practices

1. Initialize Once

Only call init once per page load:

// ✅ Good
SiteAssist("init", { apiKey: "YOUR_API_KEY" });

// ❌ Avoid
SiteAssist("init", { apiKey: "YOUR_API_KEY" });
SiteAssist("init", { apiKey: "YOUR_API_KEY" }); // Don't initialize twice

2. Handle Errors Gracefully

Check if SiteAssist is loaded before calling:

if (window.SiteAssist) {
  SiteAssist("open");
} else {
  console.warn("SiteAssist not loaded yet");
}

3. Respect User Intent

Don’t auto-open too aggressively:

// ✅ Good - give users time to browse
setTimeout(() => {
  if (!userHasInteracted) {
    SiteAssist("open");
  }
}, 30000); // 30 seconds

// ❌ Annoying - too soon
setTimeout(() => {
  SiteAssist("open");
}, 1000); // 1 second - too fast!

Error Handling

The SiteAssist API fails silently to avoid breaking your website. However, you can check the console for warnings:

// Check if API is available
if (typeof window.SiteAssist === "undefined") {
  console.warn("SiteAssist is not loaded");
}

// Wrap critical calls in try-catch if needed
try {
  SiteAssist("open");
} catch (error) {
  console.error("Failed to open widget:", error);
}
