Stripe

This page is about a feature which is still in development. It has not been released.

Description

Using Stripe, AppStudio developers can integrate payment processing into their websites without having to register and maintain a merchant account. Stripe accepts all major credit cards, plus BitCoin and AliPay.

The Stripe control makes it easy to collect payment from your customers directly within your app.

Start by setting up a Stripe account for yourself. You'll need to enter information about your company, including bank account information (so Stripe can transfer to you).

The following properties can be set up in the IDE. They can also be changed at runtime, by reference them as [controlname].data.[property]:

 Stripe1.data.amount = 1000

When the user clicks on the Stripe button, a popup appears. The appearance of the popup depends on the properties. Here's a minimal popup:

When the user fills in the information and click on the Pay button, the information is sent to a PGP script. This script needs to be saved on the same server as your app is loaded from for security reasons.

The PHP script is quite simple - it reads the information sent from your app and calls Stripe for authorization.

    //include the Stripe libraries for PHP
    require_once '/usr/home/nsbasic/stripe-php-3.9.0/init.php';

    //Supply the private key. Issued by Stripe
    \Stripe\Stripe::setApiKey("••••••••••••••••••••••••••");

    // Create the charge on Stripe's servers - this will charge the user's card
    try {
      $stripe = $charge = \Stripe\Charge::create(array(
        "amount" => $_POST['amount'],
        "currency" => $_POST['currency'],
        "source" => $_POST['stripeToken'],
        "description" => $_POST['description'],
        "metadata" => $_POST['metadata']
      ));
    } catch(\Stripe\Error\Card $e) {
      echo "Declined.";
      break;
    }

The PHP script requires the Stripe libraries be installed on your server. Instructions for doing this are here: https://github.com/stripe/stripe-php#manual-installation

When the script completes, it returns a response object.
