Before you start

A phone number that has WhatsApp or WhatsApp Business on it.
Owner or manage-settings access to your Slaby admin.

Step by step

1
Set your contact phone — with the country code
In your Slaby admin
Go to Settings → Branding and fill in Contact phone with your WhatsApp number INCLUDING the country code, for example +91 98765 43210. Save.
As soon as a valid number is saved, product pages show an 'Enquire on WhatsApp' button that opens a chat with the product name, SKU and link pre-filled. No price is ever put in the message.
A 10-digit number without +91 opens a chat with the wrong number or none at all. WhatsApp needs the full international number.
2
Turn on the floating WhatsApp button (optional)
In your Slaby admin
Go to Settings → Storefront display and switch on Floating WhatsApp button. A chat button then sits on every storefront page.
It only appears when the contact phone is a valid number — a button that opens a dead chat is worse than none.
3
Use WhatsApp Business for a business profile (recommended)
On your phone
Install the free WhatsApp Business app on the number you used. It lets you add your store name, address, hours, a greeting message and quick replies, so enquiries look professional.

Test it

1.Open a product page on your phone and tap Enquire on WhatsApp — WhatsApp should open a chat with your number and the product pre-filled.
2.If you turned on the floating button, it should appear in the corner of every storefront page.

If something goes wrong

The WhatsApp buttons do not appear.

Why it happens: No contact phone is saved, or it is too short to be a full international number.

How to fix it: Save the contact phone in Settings → Branding with the country code (+91…).

The chat opens with the wrong person or says the number is not on WhatsApp.

Why it happens: The country code is missing or the number has an extra 0 in front.

How to fix it: Enter it as +91 followed by the 10-digit mobile number, with no leading 0.

Common questions

Do I need the WhatsApp Business API or a provider like Gupshup?: No. The chat buttons use WhatsApp's free click-to-chat links, which work with any WhatsApp or WhatsApp Business number.
Can wholesale visitors who can't see prices still enquire?: Yes — that is exactly what the enquiry button is for. The message names the product but never includes a price.
