What is a WhatsApp Linktree (or “Linktree wa”)?
People search “linktree wa” and “whatsapp linktree” because they want two things at once: a single link for their Instagram bio, and a button on it that starts a WhatsApp chat. A plain Linktree can hold a WhatsApp link like any other URL. A page built for WhatsApp selling goes further: the chat button opens with a message already typed, and next to it sit your prices, your UPI ID, your hours and your location.
This suits home bakers, boutiques, tiffin services, tutors, repair shops and anyone whose customers prefer to ask “price?” on chat before they buy. Biolinko is made in Kolkata, and the WhatsApp chat and UPI payment blocks are both on the Free plan.
How WhatsApp click-to-chat links work
Every WhatsApp button is built on a click-to-chat link in this format:
https://wa.me/919876543210?text=Hi%2C%20I%20want%20to%20order
- The number is in international format: country code first (91 for India), then the number, with no plus sign, spaces or leading zero.
- The
textpart is the message that appears ready to send. It must be URL-encoded, which is why spaces turn into%20.
You do not have to write this by hand. The free WhatsApp Link Generator builds the link from your number and message, and Biolinko's WhatsApp chat block does it for you inside your page. Use the generator when you need a raw link for a Google Business listing, an email signature or a printed flyer.
Recommended WhatsApp link in bio page setup
Here is a page for a home bakery that takes orders on WhatsApp. Swap the details for your own business. Blocks, top to bottom:
- Header: logo, shop name and one line, “Eggless cakes, Salt Lake, Kolkata. Order 1 day ahead.”
- WhatsApp chat: “Order on WhatsApp” with the prefilled message “Hi! I saw your page and want to order a cake for (date).” A prefilled message saves you from “hi” and “price?” back-and-forth.
- Price list: your items and prices, so people ask about the order, not the price.
- Link buttons to your catalogue: your WhatsApp Business catalogue link, a Google Drive photo album or a menu PDF.
- Image grid: six photos of best sellers. Photos sell food, clothes and jewellery better than words.
- UPI payment: a fixed amount for advance booking (for example ₹200) or an open amount for any order.
- Business hours: so late-night messages come with the right expectation.
- Map: directions for pickup.
- Save contact: a vCard button so customers save your number with your shop name, which also helps your broadcast messages reach them.
Two chat buttons can help if you split work: one “Order” button to your sales number and one “Track my order” button to a helper's number, each with its own message.
How to set up your WhatsApp link in bio, step by step
- Create a free page with your shop name, for example biolinko.me/sweetcrumbs.
- Add the WhatsApp chat block. Enter your number with country code and write your prefilled message.
- Add the Price list, UPI payment (your UPI ID and amount), Business hours and Map blocks from the setup above.
- Pick one of the 8 free themes that matches your packaging colours.
- In WhatsApp Business, open Settings, then your business profile, and paste your page into a Website field. WhatsApp Business gives you two, so the second can hold your Instagram or Google listing.
- Paste the same link into your Instagram bio and your WhatsApp Status now and then.
- Send yourself a test: tap the chat button from another phone and check the message and number are right.
Order on WhatsApp, pay by UPI
The UPI payment block opens the customer's UPI app (GPay, PhonePe, Paytm) with your UPI ID and amount filled in. The usual flow is simple: the customer chats, you confirm the order, and they tap the UPI button on your page. Check your UPI app for the payment before you dispatch.
If you sell digital items such as recipe e-books or class recordings, Biolinko Pro (₹299/month in India, $5 elsewhere) adds a Product block. Buyers pay by UPI, card, netbanking or wallet into your own Razorpay account with a 0% platform fee, the file is delivered automatically, and each order appears in your Sales dashboard.
When you need something else
- You only need a chat link. If WhatsApp is the only place you sell, a wa.me link from the generator in your Instagram bio is enough.
- You need a cart and checkout for physical products. Biolinko has no shopping cart. Use a store builder for that, and link to it from your page.
- You want a QR code for your counter. Use the free QR code generator with your page address and print it. It can also make a WhatsApp QR code that opens a chat with you directly.
