How it works

How to create a WhatsApp deep link

Paste your WhatsApp link

Drop a wa.me click-to-chat link or WhatsApp group/invite URL into the box above.

Get your deep link

U2L returns a short link that knows how to open WhatsApp's native app on a phone.

It opens in the app

Use it as a support button, in ads, or a QR code - taps open a ready-to-send chat in WhatsApp.

What is a WhatsApp deep link?

A WhatsApp deep link opens a conversation inside the WhatsApp mobile app rather than a browser. The most common form is a wa.me 'click-to-chat' link, which starts a chat with a specific number - often with a pre-filled message. You generate one from a number or an existing wa.me link.

Businesses use these so a tap goes straight into a chat, where support and sales conversations actually happen. A link that lands in a browser adds a step and loses the lead - especially on mobile, where most WhatsApp traffic is.

Worth knowing the terms: a deep link is the general idea of opening a specific in-app screen. A universal link is Apple's https-based version on iOS; an app link is Android's. U2L applies the right one per device, so there's nothing for you to configure.

And there's no SDK or code to add. Developer chat-link tools want integration; U2L generates the link from a paste - free and instant.

FAQ

Frequently asked questions

What is a WhatsApp deep link?

A link that opens a chat inside the native WhatsApp app instead of a browser - usually a wa.me 'click-to-chat' link to a specific number. U2L generates one from a number or wa.me URL.

What is a click-to-chat link?

A WhatsApp link (wa.me/number) that opens a new conversation with a number, optionally with a pre-filled message. U2L turns it into a deep link that opens the app directly.

Do I need an SDK or any code?

No. U2L generates the link from a pasted link - there is nothing to install, configure, or ship.

Is the WhatsApp deep link generator free?

Yes - generating links is free and needs no account. Sign up free only if you want click analytics and link management.

Does it work on both iPhone and Android?

Yes. U2L opens the native app on iOS and Android and falls back to the web if WhatsApp isn't installed.

Can I pre-fill a message?

Yes - if your wa.me link includes a pre-filled text parameter, the chat opens with that message ready to send.

What's the difference between a deep link and a universal link?

A deep link is the general concept of opening a specific in-app screen; a universal link is Apple's https-based way of doing it on iOS (Android's version is an app link). U2L handles the right one per device automatically.

Can I track clicks on my WhatsApp deep links?

Free links are anonymous with no analytics. Create a free U2L account to track clicks, devices, and locations on every link.
