Build a WhatsApp click-to-chat link, format the phone number correctly, encode a pre-filled message, and test the final URL.
How to Create a WhatsApp Link with a Pre-filled Message
A click-to-chat link can reduce friction for customers who want to contact a business or team. Instead of asking someone to copy a phone number and type an opening message, the link opens a WhatsApp conversation with the number and an optional pre-filled message.
What the link needs
The phone number should be written in international format, without spaces, brackets, or a plus sign in the URL value. The message should be URL-encoded so spaces and punctuation do not break the link. Keep the message short and make sure it is an invitation to start a conversation—not a claim that the user has already agreed to anything.
Create the link
- Choose the destination phone number and confirm the country code.
- Write a helpful opening message, such as a request for a quote or a product question.
- Use Bagiqo’s WhatsApp link generator to assemble the URL.
- Test the result on a device or browser where WhatsApp is available.
Write a useful pre-filled message
Give the recipient context without making the person delete a long template. “Hello, I’m interested in the pricing for [service]. Please send me the next steps.” is more useful than a generic “Hi.” If the link is used for several campaigns, vary the message or include a simple reference that helps the team understand where the conversation started.
Test before publishing
Check that the number is correct, the message is readable, and the link works on mobile and desktop paths relevant to your audience. Test punctuation, line breaks, accented characters, and ampersands. Also check that analytics or link shorteners do not alter the destination unexpectedly.
Privacy and expectations
Tell users what will happen when they click. A WhatsApp link does not replace consent requirements or a clear privacy notice. Keep customer data out of URLs unless there is a specific, reviewed reason to include it.
Conclusion
A reliable WhatsApp link combines a correctly formatted number, a concise message, and real-device testing. Generate it once, then verify the exact link wherever you publish it.
