Unified Payment API for Synchronous and Asynchronous Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-commerce payment systems face challenges in seamlessly supporting both synchronous and asynchronous transactions, requiring developers to code for multiple systems and leading to increased complexity and user dissatisfaction.
Innovation Solution
An application programming interface (API) is introduced that allows e-commerce applications to perform both synchronous and asynchronous transactions, providing a unified interface that can be expanded to accommodate new payment systems without requiring changes to the e-commerce applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If developers code for multiple payment systems separately, then each payment system can be optimized, but application complexity and development difficulty increase
Solution Approach 1:
The patent implements a universal payment interface that can handle multiple payment systems (synchronous and asynchronous) through a single unified API. The interface includes a base class with common payment functionality and supports inheritance from multiple payment system classes, allowing one codebase to serve multiple payment providers without requiring separate optimized code paths for each system.
Solution Approach 2:
The patent introduces an intermediary layer in the form of a payment interface base class and abstract methods that mediate between the e-commerce application and various payment systems. This intermediary layer handles the complexity of different payment protocols internally while presenting a consistent simplified API to the application, thus reducing development complexity while maintaining system optimization.
2Reliability
If developers implement separate code for synchronous and asynchronous payment systems, then each payment type can be optimized, but development time and maintenance difficulty increase
Solution Approach 1:
The patent creates a universal payment interface that handles both synchronous and asynchronous payment types through a single unified API. The base class includes common payment logic that works for both types, and developers only need to implement the specific asynchronous handling logic once, reducing development time while maintaining optimization for each payment type.
Solution Approach 2:
The patent segments the payment system into a base class with common synchronous payment functionality and separate abstract methods for asynchronous handling. This segmentation allows developers to inherit the common functionality and only implement the specific asynchronous logic once, reducing development time while maintaining optimized processing for both payment types.
3Ease of operation
If a unified payment interface is implemented, then developer burden is reduced, but flexibility to handle different payment system requirements may be compromised
Solution Approach 1:
The patent implements a universal payment interface that maintains adaptability to different payment systems through inheritance mechanisms. The base class provides common functionality while allowing derived classes to override specific methods to handle different payment system requirements, thus achieving both ease of use and system adaptability.
Solution Approach 2:
The patent introduces dynamic method overriding and abstract methods that allow the unified interface to adapt its behavior based on the specific payment system being used. The interface can dynamically adjust its operation based on whether the payment system requires synchronous or asynchronous handling, maintaining flexibility while simplifying developer interaction.
Data Source
AI summary
An applications programming interface (API) or other interface may be configured for use with a plurality of e-commerce applications and/or a plurality of payment systems. The API may be associated with an operating system of a client or may be otherwise located in an e-commerce system or network. The API may receive a call regarding a purchase transaction. The purchase transaction may be examined to determine if a payment method is synchronous or asynchronous. An appropriate payment system may be activated to perform the purchase transaction based at least in part on the determination made by the examination of the purchase transaction. A result of the purchase transaction may be sent to the e-commerce program. By revision of the API, developers of e-commerce applications are freed from the burden of revising code in response to the need to utilize additional or differently operated payment systems.
