This section covers everything you need to programmatically integrate Ansa into your applications. Whether you’re building a custom chat experience, syncing data with external systems, or personalizing conversations based on user identity.

​
Choose Your Integration

JavaScript SDK

Server-side and client-side SDK for Node.js, browsers, and TypeScript. Full API access with streaming support.

Widget API

Control the chat widget programmatically — open, close, send messages, and listen to events.

Forms & Triggers

Trigger forms programmatically and handle submissions with custom callbacks.

User Identity

Pass user context to personalize conversations and pre-fill forms with known data.

Custom Events

Track user actions and trigger automations based on custom events.

Webhooks

Receive real-time notifications when conversations happen or forms are submitted.

​
Quick Start

The simplest way to add Ansa to your site. Add this script before the closing </body> tag: 
<script src="https://widget.ansa.so/embed.js?agentId=YOUR_AGENT_ID"></script>
The ansa object is automatically available on window for programmatic control: 
// Open the chat widget
ansa.open();

// Open with a pre-filled message
ansa.open("I need help with my order");

// Close the widget
ansa.close();

// Identify the current user
ansa.identify({
  userId: "user_123",
  userMetadata: {
    name: "Jane Smith",
    email: "[email protected]",
    plan: "pro"
  }
});

​
Option 2: JavaScript SDK

For server-side integrations or custom chat interfaces, install the SDK: 
npm install @ansa/sdk

import { AnsaClient } from "@ansa/sdk";

const ansa = new AnsaClient({
  apiKey: "ansa_sk_...",
});

// Send a message and get a response
const response = await ansa.chat("agent_id", {
  message: "What are your business hours?",
  conversationId: "conv_123", // optional, for multi-turn
});

console.log(response.message);

The widget runs in an iframe for security isolation. Your page communicates with the widget via postMessage, and the widget communicates with the Ansa API. Webhooks notify your server of events in real-time.
