How to create a WhatsApp link and QR code
Using the link and QR code generator, you can create a WhatsApp chat link and a WhatsApp QR code together, both built from a single welcome message. This helps customers reach you instantly, with a message already pre-filled and ready to send.
Step 1: Log in to DoubleTick & go to homepage Log in to your DoubleTick account using your registered phone number and OTP. Once logged in, the Chat section will open by default. Hover over the left navigation panel to expand the menu, then click Homepage.
Step 3: Locate the quick links section On the homepage, you'll see your API phone number, status, messaging limit, and account quality. Scroll down slightly, and on the right side you'll find Quick links.
Step 4: Open the link or QR code generator Inside Quick links, click either WhatsApp link generator or WhatsApp QR code generator — both open the same generator tool in a new tab.
Step 5: Enter your API number
Enter the WhatsApp API number you want customers to reach, and make sure the country code is correct — for example, +91XXXXXXXXXX.
Step 6: Add a welcome message Add a welcome message, for example: "Hi, I want to know more about your products." This message appears pre-filled when customers open WhatsApp.
Step 7: Generate the link and QR code Click Generate. DoubleTick instantly provides your WhatsApp chat link and WhatsApp QR code, both at the same time.
Step 8: Copy or download You can now copy the chat link, open it directly in WhatsApp, or download the QR code by clicking Download.
Once that's done, whenever a customer clicks the link or scans the QR code, they land on your WhatsApp API number with the welcome message already typed — they just press send.
