Unknown paymentMethodNonce on Braintree

Question

Hello I try to set up a braintree payement on my website but I have an error when i create my Transaction sale : Unknown paymentMethodNonce. I generate a client token like an example from Braintree support (They sand me a mail with an example) :

<?php
require_once("../lib/Braintree.php");
$clientToken = Braintree_ClientToken::generate(); ?>
...
<script>
var clientToken = "<?php echo $clientToken; ?>";
braintree.setup(clientToken, "dropin", {
        container: "payment-form"
    });
</script>

And on my checkout page :

require_once("../lib/Braintree.php");

$nonce = $_POST["payment_method_nonce"];

$result = Braintree_Transaction::sale([
    'amount' => "100",
    'paymentMethodNonce' => $nonce,
    'options' => [
        'submitForSettlement' => True
    ]
]);

I try to remove configuration line, it's work but the account merchant is not mine and if I set up the account in sale with :

    'merchantAccountId' => 'MyAccount',

or to configure before :

Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('xxx');
Braintree_Configuration::publicKey('xxx');
Braintree_Configuration::privateKey('xxxxx');

But I have an error : Exception need to be catch .

Thanks for your help

_{Full disclosure: I work for Braintree.}

The error you are getting suggests the payment_method_nonce is not reaching your server. Make sure you have a form like this in your client:

<form id="checkout" method="post" action="/checkout">
  <div id="payment-form"></div>
  <input type="submit" value="Pay $10">
</form>

You need to configure your application with the Braintree_Configuration::environment, merchantId, publicKey, and privateKey. You would only pass in merchantAccountId with a Braintree_Transaction::sale if you want to use a merchant account that is not your default account.

If you are still having trouble, please continue working with Braintree support.
