What are some alternative methods for handling Webhook data in PHP if $_POST is empty?

When handling Webhook data in PHP, if $_POST is empty, you can try accessing the raw input data from the request body using file_get_contents('php://input'). This method allows you to retrieve the raw HTTP POST data sent by the webhook. You can then parse and process this data accordingly.

// Access raw input data from the request body
$input_data = file_get_contents('php://input');

// Parse the raw input data as needed
$data = json_decode($input_data, true);

// Process the webhook data
if(!empty($data)) {
    // Handle the webhook data here
} else {
    // Handle the case where no data is received
}
