:wave: Have you checked the JSON of the request to see if it’s a valid request body? :slightly_smiling_face:

Hello yes, it is correct because I am using quick start sample project and I only changed the keys of my app I did it exactly as the example online so I don’t see where the problem is.
This is the url where I’m testing it: Square Web Payments Quickstart

Looking at the logs you are successfully creating a token for the payment request. Also I see that you have just successfully taken a payment. Did you figure out the issue?

Yes, I generate token with this:

<div id="card-container"></div>

<button id="card-button" type="button">Pay</button>
my problem now is with the payment I use this code: <?php $token = ""; if (isset($_POST["token"])) { 
$token = $_POST["token"];

}

$precio = “”;
if (isset($_POST[“precio”])) {

$precio = $_POST["precio"];

}

$amount_money = new \Square\Models\Money();
$amount_money->setAmount(2000);
$amount_money->setCurrency(‘USD’);

$body = new \Square\Models\CreatePaymentRequest(
‘cnon:CBASEEjQm2rSKpGpWP_8c-T9eWM’,
‘437861’,
$amount_money
);

$api_response = $client->getPaymentsApi()->createPayment($body);

if ($api_response->isSuccess()) {
$result = $api_response->getResult();
} else {
$errors = $api_response->getErrors();
}

?>
I get the error class SquareClient don’t found I’m new at this so I am a little lost.

Everything looks to be correct. Did you setup a .env ?
