Python is one of the most widely used programming languages when it comes to advanced software development. It comes with a wide range of powerful and robust features that make it an ideal language for developers. One of the best features Python offers is the ability to send a WhatsApp message using Python. This opens up whole new possibilities for developers to integrate automated messaging features into their apps to create an enhanced user experience.

In this article, we will go over the step-by-step guide to sending WhatsApp messages with Python. We will walk through a simple example that contains all the essential steps and concepts necessary to successfully send messages from Python.

What You Will Need to Send WhatsApp Messages​

The first thing you need to do before you can send WhatsApp messages from Python is to get the necessary components and tools. This includes getting a Twilio account, downloading and installing the Twilio Python SDK, as well as the necessary Python libraries.

Twilio​

The first step is to create a Twilio account, which is a software development platform that offers an API specifically for WhatsApp messages. Twilio provides an easy-to-use, straightforward API that allows developers to integrate automated messaging features into apps. Twilio offers an array of features and flexibility to quickly get up and running with WhatsApp automated messaging.

Twilio Python SDK​

Once you have created a Twilio account, you will need to download and install the Twilio Python SDK. This software library allows developers to quickly and easily build automated messaging solutions using Python. The SDK comes with all the necessary documentation, tutorials and code snippets that you need to get started.

Python Libraries​

In addition to the Twilio Python SDK, you will also need to install a couple of Python libraries. These libraries will allow you to make the necessary API calls to send WhatsApp messages from Python. The libraries you need to install include requests and aiohttp.

Setting up the WhatsApp Sandbox​

Before you can actually send WhatsApp messages, you need to set up the WhatsApp sandbox. This sandbox is a testing environment that uses a special API to connect to WhatsApp's servers. It allows developers to test out messages and automate messages without using any real accounts.

Setting up the WhatsApp Sandbox Account​

The first step to setting up the WhatsApp sandbox is to create a sandbox account on Twilio. To do this, go to the Twilio Console and select the "Sandbox for WhatsApp" option. Fill in your details and press the "Create Sandbox for WhatsApp" button. After a few minutes, your sandbox account will be created and you can start sending messages.

Connecting your App to the Sandbox​

Next, you need to connect your app or script to the sandbox account using the WhatsApp API. This can be done in a few different ways, but the most common way is to use the Twilio Python SDK. To do this, first import the necessary SDK libraries into your Python script and then use the “client” object provided by the SDK library to set up the connection.

Sending Messages on WhatsApp​

Now all that’s left to do is to actually send the messages. Since we are using the Twilio Python SDK to access the WhatsApp API, all that’s required is to make a few simple lines of code. First, create a “message” variable and set it to the message you want to send. Then use the “client” method to send the message with the “send_message” command.

For example, the following code will send a WhatsApp message containing “Hello World” to a specified recipient:

message = "Hello World" 
client.messages.create(to="<recipient_number>", body=message)

Once you have sent the message, you can check the response to make sure that it was sent successfully. You can also use the “messages.list” command to get a list of all the messages that have been sent.

Conclusion​

In this article, we discussed how to send WhatsApp messages using Python. We went over the step-by-step guide to getting all the components and setting up the WhatsApp sandbox. We also discussed the necessary Python libraries and how to use the WhatsApp API to connect to the sandbox. Finally, we went over the code to actually send the messages. With the steps outlined in this tutorial, you should now be able to send WhatsApp messages with Python.
