WhatsApp Link GeneratorWhatsApp 链接生成器

A WhatsApp click-to-chat link opens a conversation with you directly — no saving your number, no searching, no typing. It is the single highest-converting button you can put on a Malaysian website, and it is also the one most often built wrong.

The one rule: international format, digits only

WhatsApp will only accept a number written as country code followed by the number, with nothing else. No plus sign. No spaces. No dashes. No brackets. And critically, no leading zero.

The leading zero is where nearly everyone gets caught. In Malaysia we write mobile numbers as 012-345 6789, but that first 0 is a national trunk prefix — it only means anything when you dial from inside Malaysia. In international format it is replaced by the country code 60. It is not kept as well.

Note the third row especially: +60 012-345 6789 is wrong in both directions. Once you have added 60 you must drop the 0, otherwise you end up with 600123456789 and WhatsApp reports the number as invalid.

"The phone number shared via url is invalid"

If your link produces this message, it is almost always one of four things:

• The leading zero is still in the number — wa.me/60123456789 works, wa.me/600123456789 does not.
• The plus sign was left in. wa.me/+60123456789 fails; the plus belongs in the display format, not the URL.
• Spaces or dashes survived, often because they were pasted from a contact card and turned into %20 in the link.
• The country code is missing entirely, so WhatsApp reads a Malaysian number as an incomplete international one.

A number that is correctly formatted but simply has no WhatsApp account gives a different message — WhatsApp will offer to invite them instead. That tells you the format is fine and the account is the problem.

wa.me or api.whatsapp.com?

Both are official WhatsApp endpoints and both do exactly the same thing. wa.me/60123456789 is shorter and reads better in print, on a business card or in an Instagram bio. api.whatsapp.com/send?phone=60123456789 is longer but historically behaves a little more reliably inside the in-app browsers used by Facebook, Instagram and TikTok. If most of your traffic comes from social media ads, the api form is the safer default; otherwise use wa.me.

Prefilled messages

Adding ?text= puts a message in the customer's input box before they have typed anything. They can still edit it, and nothing is sent until they press send. Two practical uses:

• Qualify the enquiry. "Hi, I'd like a quote for a 3-bedroom unit deep clean" saves an entire round of back-and-forth.
• Track where they came from. Use a different prefilled message per channel — one for your Instagram bio, one for your Google Business Profile, one for the flyer. When the message arrives you know instantly which one is working, without any tracking pixel.

The message has to be URL-encoded — spaces become %20, and line breaks become %0A. This tool does that for you. Keep it reasonably short; very long links get truncated by some in-app browsers.

Where to actually put the link

• Your website — a floating button in the bottom-right corner, plus one at the end of every service section.
• Google Business Profile — as the appointment or booking link. Many Malaysian customers will tap this before they ever reach your website.
• Instagram and TikTok bios — use the short wa.me/60… form.
• Facebook and Instagram ads — as the destination URL, though a Click-to-WhatsApp ad objective usually performs better.
• Printed material — as a QR code on a flyer, table tent, receipt, delivery box or shop window. The QR on this page encodes the full link, prefilled message included.
• Email signature — the HTML button on this page is self-contained and works in most email clients.

You do not need WhatsApp Business API

Click-to-chat links work with an ordinary personal WhatsApp account, with the free WhatsApp Business app, and with the API. There is nothing to sign up for, nothing to verify and nothing to pay. The free WhatsApp Business app is still worth having for the catalogue, quick replies, away messages and labels — but the link itself works either way.

Nothing is stored

Your number, your message and the QR code are all produced by JavaScript running in your browser. Nothing is uploaded, logged or shortened through anyone's redirect service. The link points straight at WhatsApp's own domain, so it will keep working regardless of what happens to this website.
