Are you looking for a way to send messages using WhatsApp without having to manually open the app? Look no further! In this article, we will explore how to use a free WhatsApp API to send messages.

Using the WhatsApp API

----------------

To get started with the WhatsApp API, first, make sure that your phone number is associated with your WhatsApp account, including the country code. Then, you can use the following URL structure to send a message:

`https://api.whatsapp.com/send?phone=&text=&apikey=`

In this URL, `` should be replaced with the recipient's phone number without the leading plus sign and without any spaces or special characters. `` is the text message you want to send, and `` is the API key you received during the activation process.

Here are some things to keep in mind when using this API:

* The messages can be delayed up to 1 minute due to the fact that the API is still in beta testing.

* You can use WhatsApp formatting characters to format your message. For example, you can use `*` for bold text.

* If you want to include emoticons in your message, you can check out the online converter provided by WhatsApp.

How it Works

----------

When you click the 'Send' button, the onSubmit function is invoked. This function checks if the message length and the mobile number length are greater than one, so that empty texts are not sent. If all is well, then we call the window.open() method with the URL to open WhatsApp in a new tab.

Troubleshooting

-----------

If you have problems using this API, don't hesitate to contact me in Telegram by email at 'your email address'. You can also try using the Web Browser assistant to test the API and troubleshoot any issues.
