The short answer
- Whapi adds a WhatsApp chat button, a popup and a newsletter signup widget to your Shopify storefront.
- Tapping the button opens a WhatsApp chat with your own business number, so questions arrive where you already answer customers.
- Messages customers send are free. Your replies within 24 hours are service messages: 1,000 free per number each month, then Meta’s per-message rate, with no markup from Whapi.
- The popup and newsletter signup collect the WhatsApp opt-ins Meta requires before you send offers.
- Included on Pro ($18.99 per month or $149 per year) and Team ($45 per month), with a 7-day free trial.
More than a button: part of a full Shopify WhatsApp integration
The chat button uses the same WhatsApp Business number as your automations, so a shopper who asks a question today gets their order confirmation on the same chat tomorrow.

Where to put a Shopify WhatsApp button and what it should say
Put the button where shoppers hesitate, and open the chat with a message that tells you what they are looking at. The shopper can still edit it before they send.
| Where | Questions it catches | Opening message idea |
|---|---|---|
| Product pages | Size, color, stock and delivery time | “Hi, I have a question about this product.” |
| Cart | Delivery fees, payment options, discount codes | “Hi, I have a question before I check out.” |
| Contact or help page | Order status, returns, address changes | “Hi, I need help with my order.” |
| Every page, as a floating button | Anything, from first-time visitors | “Hi, I have a question.” |
A plain WhatsApp link vs the Whapi chat button
A plain click-to-chat link is free and works with any WhatsApp number. The Whapi chat button adds a popup and newsletter signup, and uses the same number as your automations.
| Plain WhatsApp link in your theme | Whapi chat button and popup | |
|---|---|---|
| Price | Free | Included on Pro ($18.99/month) and Team |
| Setup | Paste a link into a menu, button or footer | Set up and switch on in Whapi |
| Popup and newsletter signup | No | Yes |
| WhatsApp number | Any WhatsApp number | Your number on the official WhatsApp Business API |
| Same chat as your automations | Only if it is the same number | Yes |
| Shared inbox for several agents | No | Yes, on Team |
What chats from the button cost
A chat started by the shopper costs you nothing to receive. Your replies within 24 hours of their last message are service messages. Since October 1, 2026, Meta gives each business number 1,000 free service messages a month and charges for the rest at the rates below.
After 24 hours you can only send an approved template, and offers need the shopper’s opt-in, which the WhatsApp newsletter signup collects.
| Customer’s country | Service reply, after the first 1,000 free each month | 1,000 service replies beyond the free tier |
|---|---|---|
| Germany | $0.0550 | $55.00 |
| United Kingdom | $0.0220 | $22.00 |
| France | $0.0300 | $30.00 |
| Spain | $0.0200 | $20.00 |
| Italy | $0.0300 | $30.00 |
| United States and Canada (North America) | $0.0034 | $3.40 |
| United Arab Emirates | $0.0157 | $15.70 |
WhatsApp chat button questions
Install Whapi from the Shopify App Store and connect your WhatsApp Business number. Then set up the chat button in Whapi: the button text, where it appears and the opening message. Turn it on for your storefront and test it on a phone. Shoppers who tap it start a WhatsApp chat with your number.
The chat button, popup and newsletter signup are part of Whapi’s paid plans: Pro at $18.99 per month or $149 per year, and Team at $45 per month. Both start with a 7-day free trial. If you only need a plain link to your WhatsApp number, you can make one for free with the Whapi WhatsApp link generator and add it to your theme yourself.
Not for a plain link: a click-to-chat link works with any WhatsApp number. Whapi’s chat button uses the number you connected to Whapi on the official WhatsApp Business API, so the same number also sends your cart reminders, order confirmations, shipping updates and campaigns, and chats can be answered in a shared team inbox.
Yes. If you connect your number with WhatsApp coexistence, which is included on Pro, you keep using the WhatsApp Business App on your phone and see the chats there. On the Team plan, several agents can also answer the same number from the Whapi team inbox.
Messages customers send you are free. Your replies within 24 hours of the customer’s last message are service messages: Meta gives each business number 1,000 free a month, then charges per delivered message, for example $0.0550 in Germany, $0.0220 in the United Kingdom and $0.0034 in the United States (rates checked October 20, 2026). Whapi adds no markup.
Only after they opt in. You can reply freely within 24 hours of their last message, but Meta requires opt-in before you send them further messages such as offers. The opt-in must say they agree to receive messages from your business and name your business. The Whapi newsletter signup collects that opt-in on your store.
The chat button sits on your storefront and opens a WhatsApp chat with your business when a shopper taps it. The popup and newsletter signup widget invite visitors to join your WhatsApp list, so you can send them campaigns later with their consent.
Product pages and the cart matter most, because that is where shoppers ask about sizes, stock, delivery times and returns before they buy. On mobile, keep the button clear of the add to cart button and any cookie banner, and test it on a real phone.
