title: Add to Website
description: Add your Dograh voice agent to any website so visitors can talk to it.
---
### How to add it
Add your voice agent to any website using the Deploy Agent dialog in your agent's settings.
Step 1: Open the agent settings by clicking the gear icon in the top-right of the agent editor.
![Open agent settings](../images/open-settings.png)
Step 2: Scroll to the **Deployment** section and click **Configure Embed**.
![Go to Deployment](../images/go-to-deployment.png)
Step 3: Enable embedding, add your website's domain to **Allowed Domains**, choose **Floating Widget**, **Inline Component**, or **Headless (Bring Your Own UI)**, customize the button (position, color, text) if applicable, and click **Save Configurations**.
![Save configurations](../images/save-configurations.png)
Step 4: Copy the generated embed code and paste it into your web page to test your agent.

## Embed modes
| Mode | What it renders | When to use |
| --------------------- | -------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- |
| **Floating Widget** | A pill-shaped CTA button anchored to a corner of the page. | You want a turn-key chat-bubble experience that doesn't disturb your existing layout. |
| **Inline Component** | A panel rendered inside a `<div id="dograh-inline-container">` that you place in your page. | You want the agent embedded in a specific section (landing-page hero, support tab, etc.). |
| **Headless** | No UI. Only the audio pipeline plus a JavaScript API on `window.DograhWidget`. | You want full control over the UI — your own buttons, design system, framework state, animations. |
## Prerequisites
These apply to all three modes:
- Serve your page over **HTTPS** or from `http://localhost`. Browsers refuse microphone access on plain HTTP origins or `file://`.
- If you set **Allowed Domains** in the dashboard, include your test origin (e.g. `localhost`) — otherwise the widget's config and signaling requests are rejected. Leave the list empty to allow all domains.
- The embed snippet you copy from the dashboard is a single `<script>` tag that loads `dograh-widget.js` **asynchronously**. The widget auto-initializes once it loads and exposes `window.DograhWidget`. Code that registers callbacks must wait for the widget to be available.
## Floating Widget
![Floating widget shown in the corner of a host page](../images/floating-widget-example.png)
Renders a pill-shaped button (microphone icon + text) anchored to a corner of the page. Clicking it starts a call; clicking again ends it. The button auto-updates its label and color across the call lifecycle: configured text → "Connecting…" → "End Call" → "Retry" on failure.
Configure **Button Text**, **Button Color**, and **Position** (top/bottom + left/right) from the dashboard.
The host page writes no JavaScript — pasting the embed snippet is the entire integration. If you want to subscribe to call lifecycle events (e.g. analytics), see [Lifecycle callbacks](#lifecycle-callbacks-all-modes) below
## Inline Component
![Inline widget rendered inside a page section](../images/inline-widget-example.png)
Renders a panel (status icon + status text + CTA button) inside a `<div>` you place in your page. Status changes update the panel in place.
Configure **Button Text**, **Button Color**, and **Call to Action Text** from the dashboard.
### Plain HTML
Place a container `<div>` where you want the widget to render. The widget auto-attaches to it.
```html
<!-- Paste the dograh embed snippet from the dashboard somewhere on the page -->
<div id="dograh-inline-container"></div>
```
### React
Because React mounts after the widget script may have already loaded, integrate via `initInline` on first mount and `refresh` on remount. Poll for `window.DograhWidget` to handle the async script load.
```tsx
import { useEffect } from 'react';
declare global {
interface Window {
DograhWidget?: {
initInline: (options: { container: HTMLElement }) => void;
refresh: () => void;
getState: () => { isInitialized: boolean };
};
}
}
export function Assistant() {
useEffect(() => {
let retries = 0;
const tryInit = () => {
const container = document.getElementById('dograh-inline-container');
if (window.DograhWidget && container) {
const { isInitialized } = window.DograhWidget.getState();
if (isInitialized) window.DograhWidget.refresh();
else window.DograhWidget.initInline({ container });
} else if (retries++ < 50) {
setTimeout(tryInit, 100);
}
};
tryInit();
}, []);
return <div id="dograh-inline-container" />;
}
```
## Headless Mode
![Headless widget driven by host-page UI](../images/headless-widget-example.png)
In Headless mode the widget injects no UI of its own. You render whatever buttons, banners, or in-call indicators you want, and call the JavaScript API to start and end calls.
### JavaScript API
| Method / Callback | Description |
| ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `window.DograhWidget.start()` | Begin a voice call. Must be called from inside a user-gesture handler (e.g. `click`) so the browser grants microphone access. |
| `window.DograhWidget.end()` | End the active call. |
| `window.DograhWidget.onCallStart(cb)` | Fires when `start()` is invoked (status `connecting`). No payload. |
| `window.DograhWidget.onCallConnected(cb)` | Fires when the WebRTC connection is established. Payload: `{ agentId, workflowRunId, token }`. |
| `window.DograhWidget.onCallDisconnected(cb)` | Fires only if the call had connected, when teardown runs. Payload: `{ agentId, workflowRunId, token, durationSeconds }`. |
| `window.DograhWidget.onCallEnd(cb)` | Fires whenever the call session is torn down (including failed-to-connect attempts). No payload. |
| `window.DograhWidget.onStatusChange(cb)` | Fires on every status change. Callback receives `(status, text, subtext)`. Status values: `idle`, `connecting`, `connected`, `failed`. |
| `window.DograhWidget.onError(cb)` | Fires on errors (mic permission denied, server error, etc.). Callback receives an `Error` object. |
All `on*` setters are single-listener — calling the same one again replaces the previous handler.
<Note>
**About timing.** The widget script loads asynchronously, so `window.DograhWidget` may not exist at the moment your inline `<script>` first runs. The examples below assume `window.DograhWidget` is already available when registration runs. To guarantee that:
- **Vanilla JS:** wrap your registration code in `window.addEventListener('load', () => { /* register here */ })`.
- **React:** inside `useEffect`, register immediately if `document.readyState === 'complete'`, otherwise add a one-time `window.load` listener that registers on fire.
- **Click handlers** that call `start()` / `end()` don't need a guard — by the time a user clicks, the widget has long since loaded.
</Note>
### Vanilla JS
```html
<button id="talk-btn">Talk to AI</button>
<script>
let callStatus = 'idle';
const btn = document.getElementById('talk-btn');
function render() {
btn.textContent =
callStatus === 'connected' ? 'End Call'
: callStatus === 'connecting' ? 'Connecting…'
: callStatus === 'failed' ? 'Retry'
: 'Talk to AI';
}
window.DograhWidget.onStatusChange((status) => {
callStatus = status;
render();
});
window.DograhWidget.onError((err) => {
console.error('Dograh error:', err.message);
});
btn.addEventListener('click', () => {
if (callStatus === 'connected' || callStatus === 'connecting') {
window.DograhWidget.end();
} else {
window.DograhWidget.start();
}
});
</script>
```
### React + TypeScript
```tsx
import { useEffect, useState } from 'react';
type CallStatus = 'idle' | 'connecting' | 'connected' | 'failed';
declare global {
interface Window {
DograhWidget: {
start: () => void;
end: () => void;
onStatusChange: (cb: (status: CallStatus, text?: string, subtext?: string) => void) => void;
onError: (cb: (err: Error) => void) => void;
};
}
}
export function TalkButton() {
const [status, setStatus] = useState<CallStatus>('idle');
useEffect(() => {
window.DograhWidget.onStatusChange((s) => setStatus(s));
window.DograhWidget.onError((err) => console.error('Dograh error:', err.message));
}, []);
const isLive = status === 'connected' || status === 'connecting';
const label = { idle: 'Talk to AI', connecting: 'Connecting…', connected: 'End Call', failed: 'Retry' }[status];
return (
<button onClick={() => (isLive ? window.DograhWidget.end() : window.DograhWidget.start())}>
{label}
</button>
);
}
```
<Note>
`start()` must run inside a real user-gesture handler (`click`, `touchend`, etc.). Browsers refuse to grant microphone access to scripts that request it outside of one — calling `start()` from a `setTimeout` or on page load will fail with a permission error.
</Note>
## Lifecycle callbacks (all modes)
The `on*` callbacks in the [Headless JavaScript API](#javascript-api) work in **all three embed modes**, not just Headless. Use them for analytics or to trigger UI in the host page even when the widget is rendering its own UI (Floating or Inline).
```js
window.DograhWidget.onCallConnected(({ agentId, workflowRunId }) => {
analytics.track('voice_call_started', { agentId, workflowRunId });
});
window.DograhWidget.onCallDisconnected(({ workflowRunId, durationSeconds }) => {
analytics.track('voice_call_ended', { workflowRunId, durationSeconds });
});
```
`onCallConnected` and `onCallDisconnected` only fire when the call actually establishes a media connection — failed-to-connect attempts (e.g. denied mic, network failure) don't trigger them, so analytics stay clean.
