Think of webhooks as virtual messengers. When something noteworthy happens in one application, a webhook trigger sends a message to another application, letting it know about the event in real-time. It's like a digital notification system that keeps different systems updated without constant checking.

Breaking Down the PHP Code

Now, let's explore a basic example of a webhook trigger using PHP. We'll go through each part to make it crystal clear.

Let's Take It Step by Step:

1.Endpoint Configuration:

$webhookEndpoint = 'http://localhost/shreshtha/contact_management_inditech/webhook_endpoint.php';

This sets the destination where we want to send our webhook message. In simpler terms, it's like specifying the recipient's address.

2.Data Preparation:

$webhookData = array(
    'name' => $name,
    'email' => $email,
    'phone' => $phone,
    'message' => $message
);

Here, we gather the information we want to share. Imagine filling out a form – this is the data we're sending, like your name, email, phone, and a message.

3.Sending the Message:

$options = array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-Type: application/x-www-form-urlencoded',
        'content' => http_build_query($webhookData)
    )
);
$context = stream_context_create($options);
$result = file_get_contents($webhookEndpoint, false, $context);

This is like putting our message in an envelope and mailing it. We're using a POST request to send our data to the specified endpoint.

4.Checking for Success:

if ($result === FALSE) {
    // Webhook request failed
    // You might want to log this or handle errors accordingly
    echo 'Webhook request failed';
} else {
    // Webhook request successful
    echo 'Webhook triggered successfully';
}

After sending our message, we check if it was delivered successfully. If not, we print an error message. If successful, we celebrate with a success message.
