Add WhatsApp to Your Bitrix24 Website Widget

If you run a Bitrix24 website widget, you can let visitors message you on WhatsApp in one click. This guide shows how to add WhatsApp to your Bitrix24 website widget as a click-to-chat button, why the channel sometimes appears blank, and how WASync sets it up automatically.

Short answer: Connect a WhatsApp number in WASync. It registers the number as a Bitrix24 Open Lines connector with a public wa.me click-to-chat link and the WhatsApp icon, so the number becomes a selectable channel in your website widget. Tick it in the Contact Center, embed the widget on your site, and every click opens WhatsApp and routes the conversation into your CRM.

What is the Bitrix24 website widget?

The Bitrix24 website widget is a small piece of JavaScript you paste on your website. It shows a floating button that lets visitors reach you through live chat, a CRM form, a callback request, and messengers such as WhatsApp, Telegram, and Viber. Every conversation is saved in Bitrix24 Open Lines and the CRM, so nothing is lost.

The widget pulls its channels from the Open Channels (Open Lines) connected to it. That detail matters: a WhatsApp number only shows up in the widget when it is attached to an Open Line as a properly configured connector.

Can you add a WhatsApp button to the Bitrix24 website widget?

Yes — and there are two routes:

1. Bitrix24 "Instant WhatsApp" — the native option. You add a number manually in the Contact Center and it generates a click-to-chat link for the widget.
2. An Open Lines connector like WASync — your existing WhatsApp number (connected by QR or the official WhatsApp Business API) is registered as a connector, appears in the widget, and routes replies back into Bitrix24 through your own WhatsApp session.

The WASync route is the one to use when you want your real number, automatic setup, and full control of the inbound conversation inside Open Lines.

How to add WhatsApp to your Bitrix24 website widget (step by step)

1. Connect your number in WASync — scan the QR code with your phone, or connect via the official WhatsApp Business API.
2. Let WASync link it to an Open Line — on connect, WASync attaches the number to a Bitrix24 Open Line and registers it as a click-to-chat connector (with the wa.me link and WhatsApp icon) automatically.
3. Open the website widget settings — in Bitrix24 go to Contact Center → Website widget and edit your widget (or add a new one).
4. Tick the WhatsApp channel — under your Open Line's channels connected, enable the WhatsApp channel so it appears in the widget.
5. Embed the widget — copy the widget's JavaScript code onto your website, or switch it on through Sites and stores.
6. Test it — click the WhatsApp button. It opens wa.me to your number; your reply and the visitor's message appear in Bitrix24 Open Lines and on the lead or deal.

That's the whole flow. With WASync, steps 1–2 happen for you, so you really only choose where the button appears.

Why is the WhatsApp channel blank or "not working" in the widget?

This is the most common complaint — the WhatsApp channel is connected in the Contact Center, but in the widget it shows as a blank chip, a plain green circle with no logo, or it doesn't appear at all. Two things cause it:

• No public click-to-chat link. Bitrix lists a connector in the widget only when it carries a public wa.me link. If the connector points at an internal handler instead, the channel can be ticked but never renders a usable button.
• A broken icon. The connector icon has to be supplied as a proper data-URI SVG. A raw image or a missing file makes Bitrix fall back to a featureless colored circle.

WASync handles both: it publishes the wa.me link and the correct WhatsApp icon, and re-asserts them every time the number reconnects — so the button stays correct without manual fixes. If a license expires, WASync removes the channel so the client is never left with a dead button on their site.

WASync vs Bitrix24 Instant WhatsApp

Both put a WhatsApp button in the widget. WASync wins when you want your own number, zero manual icon/link fiddling, and the conversation handled inside your Open Lines and CRM.

What happens when a visitor clicks the WhatsApp button?

1. The button opens WhatsApp (wa.me) pre-filled with your business number.
2. The visitor sends a message from their own WhatsApp.
3. The message arrives on your connected number and WASync forwards it into the matching Bitrix24 Open Line.
4. Bitrix24 creates or updates a lead, deal, or contact, and your team replies from Open Lines or the CRM widget.

The visitor gets a familiar WhatsApp chat; you get a tracked CRM conversation.

Frequently asked questions

Does WhatsApp appear in the Bitrix24 website widget automatically? With WASync, yes — once the number connects it becomes available to tick in the widget. You still embed the widget code and choose which channels to show.

Why is my WhatsApp channel blank or not showing? The connector needs a public wa.me link and a valid icon. Without them Bitrix shows a blank or featureless chip. WASync sets and maintains both for you.

Can I use my existing WhatsApp number? Yes — by QR or the official WhatsApp Business API. The same number becomes the widget's click-to-chat button.

Does it work during the free trial? Yes. The button is enabled as soon as the number connects, trial included, and is removed automatically if a license expires.

Can I add more than one WhatsApp number? Yes. Each number gets its own Open Line; tick the ones you want. WASync supports multiple numbers per portal.
