Can I receive a JSON object in a POST request with PHP?

I have prepared a payment method, but it sends data in a JSON object in POST. I want to receive it and send it to the Firebase database.
Not all data, but only a certain amount.

Transaction Processed Callback

It’s an URL for an endpoint in your web app, on which you’d receive callbacks as a notification after performing any payment process from your customer side, you would receive a JSON object in POST request which contains a value by which you can know about your payments such as the status of the transaction (success/declined), the order ID related to this transition, the transaction ID and much other information related to your transaction, here’s a sample request similar to the one you should receive on your transaction processed callback endpoint.

    I faced something similar a few days ago.

    Try this:

    <?php

if ($_SERVER['REQUEST_METHOD'] === "POST") {
    $data = "";
    $fd = fopen("php://input", 'r');

    while(($chunk = fread($fd)))
        $data .= $chunk;

    $json = json_decode($data, true);
    
    if (is_null($json))
        die("Error parsing JSON request");
    
    print_r($json);
} else {
    echo "Method not supported";
}

    Hope this can help you!

    PHP has inbuilt support for when the Content-Type of a POST request is application/x-www-urlencoded or multipart/form-data. (These are used by browsers submitting HTML forms: multipart/form-data may include uploaded files; application/x-www-urlencoded is simpler and more efficient and cannot include uploaded files.) PHP will automatically parse the POST data supplied and put it into the $_POST and $_FILES superglobals.

    For any other input type, you need to to the work yourself, though in the case of JSON it should be simple enough.

    1. Get the data: $data = file_get_contents('php://input');
    2. Parse the data: $arr = json_decode($data, true);

    Putting that together, we get:

    $arr = [];
if ($_SERVER['REQUEST_METHOD'] === "POST") {
    $data = file_get_contents('php://input');
    $arr = json_decode($data, true);
}
