WhatsApp on the platform is a manual channel: wa.me links that open WhatsApp with a message already written, so the person presses send from their own phone. There is no WhatsApp Business API integration, there are no Meta-approved templates, and no message is ever sent on its own.
Where you configure it depends on your store version. If the panel header has an EDIT STORE button, you are on the new store.
Step by step
Putting the WhatsApp button on your new store
- In the panel header, click EDIT STORE.
- In the editor, open Content → Support.
- Scroll down to WhatsApp channels and add a channel.
- Fill in Channel name (for example "Sales"), WhatsApp number with the country code, and Prefilled message if you want the conversation to start with some text.
- Add more channels if you handle different areas separately.
- Save and publish the store changes.
Putting the WhatsApp button on your classic store
- In the side menu, go to Store design → Chat.
- On the Channels card, click Add channel.
- Fill in the WhatsApp number, the channel name and the Auto message.
- Under Chat settings you can also change the Title, the Availability and the Welcome text the buyer sees when opening the chat.
- Under FAQs, load the questions the chat answers before handing off to WhatsApp.
- Save the changes.
Recovering an abandoned cart over WhatsApp
- In the side menu, go to Sales → Customers.
- Find the customer and click the indicator in the Cart column.
- On the cart page, the Send a message with a link to complete the purchase card carries the editable message and the recovery link.
- Edit the text if you want and click Send via WhatsApp. WhatsApp opens with the message and the link at the end; you do the sending.
If you would rather close the sale yourself, the Complete order button in the header loads that cart into the order builder.
The number and the channels
The floating button shows the channels you loaded. With a single channel, the button links straight to that number. With several, it opens a selector so the buyer chooses who to talk to. If you loaded no channels, the store uses the main WhatsApp number saved when your business was created.
The number has to carry the country code. Only digits are kept when the link is built, so the +, the spaces and the hyphens do not get in the way: you can write +54 9 11 2345 6789 without trouble. What cannot be missing is the country code, because wa.me works with the full international number. A number without a country code produces a link that opens no conversation at all.
A channel with no digits is discarded silently. If you left the field empty or filled it with text, that channel is not shown and you will see no error.
The inquiry button on the product page
On the new store, on top of the floating button, every product page shows an Ask on WhatsApp link. It opens a conversation with a message already built that names the product and its reference, so the buyer does not have to explain which item they mean.
It uses the first channel in your list, so put the number you want product inquiries to reach at the top.
It can be switched off from the editor, under Screens → Product, with the Show WhatsApp inquiry toggle.
Why the floating button does not appear
It is the most common question, and it usually has one of these three causes:
- There is no channel with a valid number. With no channels and no main number, nothing is rendered.
- There is a panel open on top. The button is hidden while an overlay panel is up, typically the side cart. On desktop the cart opens on the right and covers exactly that corner, so the button disappears while it is open and comes back when you close it. On mobile the cart takes the whole screen and the effect is less noticeable.
- The store's AI assistant is active. When the assistant is on, it wins: the green WhatsApp button only appears when the assistant is unavailable, for instance when the monthly AI credit has run out. The assistant still offers your channels when the buyer asks to speak to a person.
The abandoned-cart message is edited on another screen
The text preloaded into the cart recovery message is configured under Settings → Communication, Others group, WhatsApp abandoned cart item. It is one of the platform's editable texts, not a loose field in the business settings.
The cart link is appended on its own at the end of the message: you do not have to write it or leave a placeholder for it.
That screen is not in the new store's menu. If you are already on the new version, the message goes out with the last text you saved, or with the default text if you never touched it. Either way you can edit it at send time: the box on the cart page is editable.
What does NOT exist
- There is no automatic sending. No WhatsApp message is sent when an order is confirmed, dispatched or invoiced, or when an abandoned cart is detected. Every message is fired by a person with a click. If you want automatic notifications, the channel is email: see Transactional emails and Auto-seller.
- There is no WhatsApp Business API. There are no Meta-approved templates, no number verification and no bulk sending. It is all the
wa.meprotocol, which opens the app of whoever taps the button. - There are no templates per message type. The only editable text is the abandoned-cart one. Every other message is built automatically from the order or product context.
- There is no delivery or read tracking. The platform does not know whether the message was sent, read or answered: that happens inside WhatsApp, outside VentasxMayor.
If you cannot find it
- You cannot find Store design → Chat in the menu. You are on the new store: channels are configured in the editor, under Content → Support. In that version the Store design section disappears from the menu entirely.
- You do not see the WhatsApp card on the cart page. It only appears if that customer has a mobile number loaded.
- You are looking for the WhatsApp buttons on invoices. The ones on an invoice's detail belong to VentasxMayor's own billing and have nothing to do with your catalog's orders.
Tips
- Load separate channels per area (Sales, Support, Billing) when different people handle different topics. The buyer picks and the question reaches the right person.
- Write a prefilled message per channel. The buyer arrives with context and you start the conversation halfway through.
- Before publishing, test the button from your own phone. A wrong country code gives no error: it simply opens nothing.
- If you are going to use the store's AI assistant, leave the channels loaded anyway: the assistant needs them to hand off to a person.
- For bulk reach with WhatsApp you will need WhatsApp Business or a provider connected to Meta's API. VentasxMayor does not replace those tools: it makes the one-to-one click easy from the panel.
