Web link to specific whatsapp contact - html

Question

I'd like to place a link on a webpage which opens a whatsapp chat with a certain whatsapp contact. In other words: I want a "contact me by whatsapp" link to go next to the page's "Contact us my facebook/twitter/google+/etc" links. Something like:
href="whatsapp:contact=015555555555#s.whatsapp.com&message="I'd like to chat with you"

Answer 1

********* UPDATE ADDED AT THE END *********
I've tried many approaches and I have a winner (see Test 3), here is the result of each one:
(I think the Test 3 will also work for you because if the person visiting your site doesn't have you on their contact list, it's the only option that will allow it.)
In all tests, the number had to be complete, with country and location code without any initial zeros. Example:
[phone] (NOT)
[phone] (YES)
On tests 1 and 2, it only worked with a plus sign on the country code: [phone]
Test 1:
Send Message
This way you must have the phonenumber on your contact list. It doesn't work for me because I wanted to be able to send a message to a number which I may not have on my contact list.
If you don't have the number on your contact list, it opens the Whatsapp listing all your registered contacts, so you can choose one.
It's a good option for sharing stuff.
Test 2:
Send Message
This approach only works on Android AND if you have the number on your contact list. If you don't have it, Android opens your SMS app, so you can invite the contact to use Whatsapp.
Test 3 (The Winner):
Send Message
This was the only way that worked fully for me.
It works on Android, iOS and Web app on the desktop,
You can start a conversation with a number that you don't have on your contact list
You can create a link with one pre-built message adding &text=[message-url-encoded] like:
https://api.whatsapp.com/send?phone=15551234567&text=Send20%a20%quote
And if you wish to have a bookmarklet for additional ease of use, you may use this one:
javascript: (function() { var val= prompt("Enter phone number",""); if (val) location="https://api.whatsapp.com/send?phone="+escape('972' + val)+""; })()
Youll need to change the country code(or remove it) to you.r target country and paste it in the address field in a chrome/firefox link
Worth notice:
I had to update my WhatsApp to the latest version
The number's country code must not have a leading plus

***************** UPDATE (START) *****************
Whatsapp made available other option, now you can create one link to a conversation like this:
https://wa.me/[phonenumber]
The phone number should be in international format:
Like this:
https://wa.me/552196312XXXX
NOT like this:
https://wa.me/[phone]-XXXX
And if you want to add one pre-built message to your link, you can add ?text= at the end with the text URL Encoded:
https://wa.me/552196312XXXX?text=[message-url-encoded]
Exemple:
https://wa.me/552196312XXXX?text=Send20%a20%quote

***************** UPDATE (END) *****************

Answer 2

The following link seems to work fine -
Ping me on WhatsApp
It opens the contact in WhatsApp app, along with the message 'Hello World!' prepopulated in the input text box.
(Tested this with google chrome on an android phone.)

Answer 3

Official WhatsApp doc Says-:
https://api.whatsapp.com/send?phone=countrycode+phonenumber
Use: https://api.whatsapp.com/send?phone=15551234567
Don't use: https://api.whatsapp.com/send?phone=+001-(555)1234567
https://faq.whatsapp.com/en/general/26000030

Answer 4

You can use the following URL as per the WhatsApp FAQ:
https://wa.me/PHONENUMBERHERE
Add the country code in front of the number and don't add any plus (+) sign or any dashes (-) or any other characters in the number. Only integrers/numeric values.
You can also predefine a text message to start with:
https://wa.me/PHONENUMBERHERE/?text=urlencodedtext

Answer 5

I've tried this:
whatsapp
changing 'phonenumber' into a specific phonenumber. This doesn't work completely, but when they click on the link it does open whatsapp and if they click on a contact the message is filled in.
If you want to open a specific person in chat you can, but without text filled in.
test
You'll probably have to make a choice between the two.

Answer 6

You can now use a very simple API https://wa.me/ to perform this task where you can provide a valid whatsapp contact number like 15555555555 ( add country code, remove all '+', '-', brackets, spaces or leading zeros). You can also provide a urlencoded text as a predefined msg which user can send directly or change before sending.
Chat with me link : Contact me by whatsapp
Chat with me link with predefined text : Contact me on whatsapp
Beauty of this wa.me url is you don't need to check user agent as it works on both mobile and desktop (opens web.whatsapp.com)

Answer 7

For what its worth, as of this writing (Nov. 29, 2018), the updated API that seems to work on my end is using this link:
https://wa.me/<phone number here>
Note:
Just replace the placeholder <phone number here> with the intended phone number that you want to use INCLUDING the country code, this means I had to add +60 then the rest of the remaining number.
It doesn't work on my end without one (using Android and iOS at least). It doesn't work means an error message that says along the lines of "you don't have this number".

Answer 8

I have been struggling with how to do that as well. I managed to find this helpful method
from php variable:
href="https://wa.me/<?php echo esc_attr( $phone ); ?>?text=Hi%27,%20like%20to%20chat%20with%20you"
<?php echo esc_attr( $phone ); ?> for number in the format:
href="https://wa.me/263777300093?text=Hi%27,%20like%20to%20chat%20with%20you"

Answer 9

This approach only works on Android AND if you have the number on your contact list. If you don't have it, Android opens your SMS app, so you can invite the contact to use Whatsapp.

Answer 10

From the Official Whatsapp FAQ: https://faq.whatsapp.com/en/android/26000030/
WhatsApp's Click to Chat feature allows you to begin a chat with someone without having their phone number saved in your phone's address book. As long as you know this person’s phone number, you can create a link that will allow you to start a chat with them. By clicking the link, a chat with the person automatically opens. Click to Chat works on both your phone and WhatsApp Web.
To create your own link, use https://wa.me/ where the is a full phone number in international format. Omit any zeroes, brackets or dashes when adding the phone number in international format. For a detailed explanation on international numbers, read this article. Please keep in mind that this phone number must have an active account on WhatsApp.
Use: https://wa.me/15551234567
Don't use: https://wa.me/+001-(555)1234567

Answer 13

The solution that worked for me is here in PHP:
$android = stripos($_SERVER['HTTP_USER_AGENT'], "android");
$iphone = stripos($_SERVER['HTTP_USER_AGENT'], "iphone");
$ipad = stripos($_SERVER['HTTP_USER_AGENT'], "ipad");
$whatsappNumber = '1234597891';
$whatsappLink = '';
if($android !== false || $ipad !== false || $iphone !== false) {//For mobile
$whatsappLink = ''.$whatsappNumber.'';
} else {//For desktop
$whatsappLink = ''.$whatsappNumber.'';
}
