WhatsApp Messaging with Node.js, Example

Before diving into the code, you need to install the axios package which will be used for HTTP requests. Run npm install axios from your script's directory in your terminal.

To send a text message, you need to make a request to:

POST https://gate.whapi.cloud/messages/text

Here is an example of how to send a WhatsApp message using Node.js:

const request = require('request');

const options = {
  method: 'POST',
  url: 'https://gate.whapi.cloud/messages/text',
  headers: {
    accept: 'application/json',
    'content-type': 'application/json',
    authorization: 'Bearer iVwcoBzBcB2bsbNShV4dDCXPwp1mvBcs'
  },
  body: {typing_time: 0, to: '14409416972', body: 'Hello'},
  json: true
};

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

To run this script, save it in a .js file (for example, whapi_script.js), navigate to the script's directory in the terminal, and run the command node whapi_script.js. The message specified in the 'body' of the data object will be sent to the WhatsApp number specified in 'to'. Ensure to replace the 'to' and 'token' values with your actual details.

The parameters are as follows:

to: The recipient’s WhatsApp number in international format (e.g., 14409416972) or chatID for contact or group (e.g 14409416972@s.whatsapp.net or 12560234567890@g.us).
body: The content of the message.

This script includes basic error handling with the .catch method, logging any errors that occur during execution. For a production environment, be sure to introduce appropriate error and exception handling mechanisms.
