Step 1: Install pywhatkit

To install the last version of pywhatkit, open up a terminal and run the following command.

pip install pywhatkit

The installation might take seconds or even a minute so be patient as it involves a lot of dependencies. Once the library is installed, you can check out all the dependencies this library installed with the command pip list.

Step 2: Send a message to a contact on WhatsApp

Before we start sending messages, you have to log in to your WhatsApp account through WhatsApp Web. If you’re not logged in, your phone isn’t on the same WiFi as your computer, or the phone is far away from your computer, this method won’t work.

To send a message to a WhatsApp contact with Python and pywhatkit, we use the .sendwhatmsg method as shown in the code below (insert your contact number instead).

import pywhatkit
# syntax: phone number with country code, message, hour and minutes
pywhatkit.sendwhatmsg('+92xxxxxxxx', 'CodewithUsman Python', 18, 52)
What this code means is “Type ‘Message 1’ and send it to contact X at 18:52”

After running the code above you’ll get a message like this:
In 10 seconds, web.WhatsApp.com will open, and after 15 seconds, a message will be delivered by Whatsapp.(Default time for sending is 15 seconds you can also change it.)

That’s it! After some seconds your browser will open and the message will be sent to your contact.

Great! Now we can also customize other actions in the browser.

Say we want to close the tab 2 seconds after sending the message. We do so, running the code below.

import pywhatkit
pywhatkit.sendwhatmsg(“+92xxxxxxx”, “CodewithUsman Python3”, 18, 55, 15, True, 2)

Here the “True” indicates that we want to close the tab after “X” seconds once the message is delivered. The last argument “2” represents this “X” number of seconds.

Step 3: Send a message to a group on WhatsApp

We can also send messages to a specific group on WhatsApp, but first, we have to get the group id.

To find the id, follow these steps:

Open any group you want and click on the “Group Info” section
Scroll all the way down and look for the “Invite via link” option. Tap on that option
There you’ll see a link. Copy the link. The suffix part of the link is the id of the group.

Once you have the id of the group that you’ll use for this test, we have to use the .sendwhatmsg_to_group method. This method is similar to the one we used in step 2, but now we insert a group id.

import pywhatkit
# syntax: group id, message, hour and minutes
pywhatkit.sendwhatmsg_to_group("write-id-here", "Message 3", 19, 2)

That’s it! Note that there are other methods pywhatkit has. You can also send messages instantly using .sendwhatmsg_instantly and .sendwhatmsg_to_group_instantly but they didn’t work for me.

Just in case, below are the parameters we used in this tutorial for .sendwhatmsg and .sendwhatmsg_to_group.
