What are the potential risks of transferring sensitive data via POST to a PHP API?

Transferring sensitive data via POST to a PHP API can pose security risks if the data is not properly encrypted or secured. To mitigate these risks, it is recommended to use HTTPS to encrypt the data in transit and implement server-side validation and sanitization of the input to prevent injection attacks. 

<?php
// Example of implementing HTTPS in PHP API
if ($_SERVER['HTTPS'] !== 'on') {
    header("Location: https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}

// Validate and sanitize input data
$sensitive_data = filter_input(INPUT_POST, 'sensitive_data', FILTER_SANITIZE_STRING);
if (!$sensitive_data) {
    // Handle invalid input
}
