Click to Chat is a WhatsApp feature which helps us to do this task. It can be done on both the phone and PC.
Here are the steps to do that on PC:
Open the web browser and then paste the following on the Address bar:
In the place of “number", you need to provide the phone number with the country code (don’t enter any special characters).
Here 91 is country code (India) and the remaining is phone number (just for the example sake).
Keep in mind that the number you provided should have a WhatsApp account.
Now you should be on the screen like this:
Click on “Message" button.
It will take you to the WhatsApp Web. Scan the QR code to log in (open WhatsApp on your phone > tap Overflow menu > WhatsApp Web).
Now you can see that a chat is opened for the number you provide.
Just type the message or attach the media and hit “Send" icon.
Alternatively, you can use the following link structure to open a chat for a number along with the pre-filled message.
In the place of the number, provide the phone number along with the international code.
In the place of URLencodedtext, provide your URL-encoded message. Keep in mind that you need to use %20 for space and %3F for the question mark. For instance:
After you entered the link in the browser’s Address bar, you can see a screen like this:
Tap Send button.
Scan QR code to log into WhatsApp Web.
Now you can see that a chat is opened along with the message. Just click on "Send" icon to send the message.
