error E00001 when submitting

[kennethrudo]

Hi, I am receiving error E00001 when I call getHostedPaymentPageRequest method. I was reffering to this guide https://github.com/AuthorizeNet/accept-sample-app/blob/master/README-AcceptHosted.md  when making it.

And this is my html+php form I created to send data to https://test.authorize.net/payment/payment  

<form id="send_hptoken" action="https://test.authorize.net/payment/payment" method="post">
<input type="hidden" name="token" value="<?php echo $response->getToken(); ?>" />
<input type="submit" />
</form>

Any help would be greatly appreciated.
