Widget API - Virtual Currency

Full API Reference.

Specify the currency for your application’s virtual cash. Virtual Currency API will help you manage the currencies.

Configuration

Once you have a project created in My Projects, you can start configure your project at Settings section to make it work properly with Widget API:


Widget Call

By replacing the value of ps parameter from all to specific payment systems API short codes, you can specify payment method for single payment method.

<?php
require_once('lib/paymentwall.php');

    'api_type' => Paymentwall_Config::API_VC,

    'user40012', 
    'p1_1',

        'history[registration_date]' => 'registered_date_of_user',

Handle Pingback

Before you start, please read Pingbacks document to get an overview of Paymentwall Pingback system.

Sample Pingback Request for Virtual Currency :

http://www.yourserver.com/anypath?uid=pwuser&currency=200&type=0&ref=b1493096790&sign_version=2&sig=d94b23ba8585f29978706dd1b153ead9

Before you submit the project, please test your pingback integration using Test Pingback Tool.

You should check whether your pingback listener is :

  • responding OK to Paymentwall pingback requests.
  • filtering duplicate reference id requests.
  • filtering wrong signature requests. You can test this by checking Use a dummy value feature in Test Pingback Tool.

Success Page

If you would like to redirect the user after a payment is made, you can pass the success_url and failure_url parameters as optional parameter that will be used as the address of landing page after your users made payments. You can also use client side callback if you want to take more actions.

To enable client side callback, please contact to devsupport@paymentwall.com with your Paymentwall account email address.


Next Step

Once you have successfully integrated our widget and set up for the pingback listener, you can submit your project for review.

See project go live.
