# Web calling

> Ask your AI assistant to set up the website widget that lets visitors talk to your AI agent from their browser, and get the snippet to paste on your site.

- Section: Using the MCP (AI assistant) › Channels & integrations
- Web page: https://docs.biglysales.com/mcp/web-call
- Availability: Not enabled on every account. Contact support to turn it on
- Manual (in-app) equivalent: [Web calling](https://docs.biglysales.com/manual/web-calling.md)
- Video: placeholder — "Putting your AI agent on your website" (not yet recorded)

**Web calling** lets visitors to your website talk to your AI agent straight from their browser. There's no phone number and no dialing. You paste a short snippet into your site, and visitors click **Start call** to begin.

It's the same setup as **AI › Web Calling** in the app. Your assistant can read it, change it, give you the snippet, and issue a new snippet key if you need one.

> **Example request to your AI assistant:** "Is our web calling set up correctly? Tell me anything that would stop it working."
> "Allow the widget on example.com and app.example.com, then turn web calling on."
> "Use the Website Visitors intro for web calls."
> "Give me the snippet to paste on our site."

## Before you start

- [Connect your AI assistant](https://docs.biglysales.com/mcp/connect.md) to Bigly.
- You need permission to **read** web calling to see it, and permission to **update** it to make changes. Account owners and admins have both by default.
- Web calling must be enabled for your account. If it isn't, the assistant can still show and preview your settings, but saving fails until support turns it on.

## What the assistant reads

- Your settings: on or off, allowed domains, intro and consent text.
- **The snippet** to paste into your website, and the key inside it.
- **The consent text visitors will see**, with your company name filled in.
- **Warnings** about anything that would stop the widget working (see below).

## Set it up

1. Ask the assistant to add the domains where the widget will appear.
2. Pick the intro you want web callers to hear.
3. Review the preview: each setting with its current and new value, plus any warnings.
4. Confirm in the chat.
5. Ask for the snippet and paste it into your website's pages.
6. Ask for a [web call preview](https://docs.biglysales.com/mcp/call-context-preview.md) to read what the agent will say.

## Settings explained

| Setting | On screen | Accepted values |
|---|---|---|
| Web calling on (`enabled`) | **Enable web calling** | On or off |
| Allowed domains (`allowed_domains`) | **Allowed domains** | Up to 100 website addresses. **An empty list blocks every site.** |
| Intro (`intro_id`) | **Intro** | One of your [intros](https://docs.biglysales.com/mcp/intros.md), or none |
| Consent text (`consent_text`) | **Consent / policy text** | Up to 2,000 characters. `{company}` becomes your company name. Leave it empty to use Bigly's default consent text. |

### How domains are saved

The assistant cleans up each domain before saving, and the preview shows the cleaned version:

- `https://www.example.com/pricing` becomes `example.com`. The `https://`, `www.`, page path and port are removed.
- `www.example.com` and `example.com` count as the same site.
- Subdomains are separate: `example.com` doesn't cover `app.example.com`. Add each one you use.

## Warnings to look for

The preview and the read both warn you when the widget won't work, even though the settings are valid:

- Web calling isn't enabled for your account yet.
- Web calling is on, but no domains are allowed, so every site is blocked.
- This change empties your domain list while web calling is on, which breaks the widget on every site.
- Domains are allowed, but web calling is off.
- No intro is chosen. The default follow-up intro is used instead.
- No snippet key exists yet. One is created the first time you save.

## Get a new snippet key

If your snippet was copied somewhere it shouldn't be, ask the assistant to **regenerate the web call token**. It uses a separate confirmation from ordinary changes.

After you regenerate, the old snippet stops working everywhere it's pasted. Replace it on every page with the new snippet straight away.

## Limits and rules

- **AI calling** in [AI settings](https://docs.biglysales.com/mcp/ai-settings.md) doesn't control web calls. Web calling has its own switch.
- Web calls use your **outbound** prompt, opening sentences, intros, prompt variables and voice. Inbound settings don't apply.
- On a web-calling-only account, phone settings, SMS agents and call or text follow-ups do nothing.

## What you can't do here

- **Place a web call.** That creates a contact and a billable call, so the MCP can't do it. Use **Test web call** in the app. See [Web calling in the app](https://docs.biglysales.com/manual/web-calling.md).
- **Edit your website.** You paste the snippet yourself.
