How to create a link with a transition to WhatsApp - briefly?

To create a link that transitions to WhatsApp, you can use the following format: https://wa.me/[phone_number]. Simply replace [phone_number] with the recipient's phone number in international format (e.g., +1234567890). This link will open WhatsApp on a user's device, ready to start a new chat.

How to create a link with a transition to WhatsApp - in detail?

Creating a link that transitions to WhatsApp can be accomplished through several methods, each tailored to specific use cases and platforms. Below is a detailed guide on how to achieve this:

For Web Pages

  1. Hyperlink with WhatsApp URL Scheme:

    To create a hyperlink that opens WhatsApp directly from a web page, you can use the whatsapp:// URL scheme. Here’s an example of how to do it in HTML:

    <a href="whatsapp://send?text=Hello%20World">Send a Message</a>

    This link will open WhatsApp and pre-fill the message with "Hello World".

  2. Fallback for Devices without WhatsApp:

    It’s important to provide a fallback for users who do not have WhatsApp installed. You can achieve this by using JavaScript to detect if the link was successfully opened:

    <a href="whatsapp://send?text=Hello%20World" onclick="return !window.open(this.href)">Send a Message</a>

    If WhatsApp is not installed, this fallback prevents the link from breaking the page.

For Mobile Applications

  1. Android:

    On Android devices, you can use an Intent to open WhatsApp:

    Intent sendIntent = new Intent();
    

    sendIntent.setAction(Intent.ACTION_SEND);

    sendIntent.putExtra(Intent.EXTRA_TEXT, "Hello World");

    sendIntent.setType("text/plain");

    sendIntent.setPackage("com.whatsapp");

    startActivity(sendIntent);

  2. iOS:

    On iOS devices, you can use the LCMessage class to send a message via WhatsApp:

    if let url = URL(string: "whatsapp://send?text=Hello%20World") {
    

    UIApplication.shared.open(url)

    } else {

    // Handle error or fallback

    }

For Email and SMS

  1. Email:

    You can include a WhatsApp link in an email. However, be aware that many email clients will not recognize the whatsapp:// URL scheme and may require users to manually copy and paste the link into their browser or WhatsApp app.

  2. SMS:

    For SMS, you can send a text message containing the WhatsApp link. Recipients who tap on the link will be directed to WhatsApp if they have it installed:

    Hi! Click here to send us a message: whatsapp://send?text=Hello%20World

Handling Universal Links

If you want to create a more seamless experience, especially for users who do not have WhatsApp installed, consider using universal links. Universal links allow you to direct users to either the WhatsApp app or a web page depending on their device configuration:

<a href="https://wa.me/?text=Hello%20World">Send a Message</a>

This link will open WhatsApp Web if the user is on a desktop, or the WhatsApp app if they are on a mobile device with WhatsApp installed.

Testing and Validation

After creating your links, it’s essential to test them across different devices and platforms to ensure they work as expected. Validate that the fallback mechanisms function correctly and that users are not encountering broken links or errors.

By following these detailed steps, you can effectively create links that transition to WhatsApp, providing a smooth user experience across various platforms and devices.
