payWise Technologies Payment Gateway Developer Docs

Our payWise Technologies Payment Gateway allows you to utilize our flexible Application Program Interface (API) to connect to your software with a powerful processing platform. We have several methods available to integrate your software to the payWise Technologies Payment Gateway. The following will give you a brief breakdown of each method. These options vary based upon ease of integration, available resources, and features.

Transaction Request APIs

  • Three-Step Redirect API
For quick setup and the smallest PCI footprint, the Three-Step Redirect is the best integration method. This option allows you to quickly generate a payment form to collect and send secure customer information directly to the payment gateway.

Method Overview

  • Submit all transaction details to the Payment Gateway, except the customer's sensitive payment information. The Payment Gateway will return a variable form-url.
  • Create an HTML form to collect the customer's sensitive payment information, and use the form-url which the Payment Gateway returns, as the submit action in said form.
  • Once the customer has been redirected, obtain the token-id and complete the transaction through an HTTPS POST, including the token-id which abstracts the sensitive payment information collected directly by the Payment Gateway.
  • Direct Post API
The Direct Post API is a simple integration method for both web-based and non-web-based payment applications. This method has the flexibility to seamlessly integrate your new or existing application, for a completely transparent customer experience.

Method Overview

  • The customer sends their payment information to the merchant's website.
  • The merchant website posts the payment data to the Payment Gateway.
  • The Payment Gateway responds immediately with the results of the transactions.
  • The merchant website displays the appropriate message to the customer.
  • Mobile API
The Mobile API supports iOS and Android-based devices. This Software Development Kit (SDKs) includes a mobile card reader library, which simplifies integrations for applications requiring encrypted mobile card readers. Additionally, an end-to-end encryption library is included, allowing merchants to send both swiped and keyed-in payment information, without ever touching any sensitive data.

Android Method Overview

  • Download and extract the zip file from the integration section of the Payment Gateway.
  • In Android Studio's Quick Start menu, select 'Start a new Android Studio project'.
  • Add SDK to project.
  • Modify the Gradle build file.

Transaction Request APIs

  • Query API
While our online reporting interface allows merchants to quickly and easily retrieve detailed information about past transactions, a need for additional flexibility may be required. For example, a merchant may have custom accounting software which requires up-to-date information about the settlement status of all credit card transactions every day.

This method describes how developers can query our reporting engine directly to retrieve transaction reports in a machine readable format. Once the data has been retrieved, it can then be parsed and imported into a variety of software applications.

Turnkey Shopping Carts

  • QuickClick Shopping Cart
QuickClick is a great option for e-commerce merchants who do not have an IT team or developer on staff. A button-generator is included, which allows merchants to create website links to products and services without any previous development experience.

Here are three button types, which are very easy to setup:

  • Shopping Cart Button: Will connect products built with this button, will connect type so customers can add several products to the cart system. Also supports Recurring Billing.
  • Fixed Price Button: Does not connect to the 'Shopping Cart' system and will only process one item at a time.
  • Donation/Payment Button: Allows the customer to enter an amount and checkout.
  • Third-Party Shopping Carts
There are a number of third-party shopping carts which have integrated to the payment gateway. This is the best option for merchants who need a full featured, turn-key shopping cart out of the box.
