Authorization Routing With Acquirer Bypass for Transaction Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authorization routing in e-commerce is prone to failures due to network issues, causing authorization requests to fail when the acquirer processor is unavailable, leading to incomplete transactions.
Innovation Solution
Implementing a bypass communication channel that allows authorization requests to be routed directly to the payment network when the acquirer processor is unavailable, ensuring seamless transaction processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authorization routing is used through the acquirer processor, then transaction authorization can be processed through the standard payment network, but the system becomes vulnerable to failures when the acquirer processor is unavailable
Solution Approach 1:
The system performs preliminary actions by establishing multiple communication channels (first channel through acquirer processor, second channel bypassing acquirer processor) before failures occur. The gateway server is pre-configured with alternative routing paths so that when the primary acquirer processor becomes unavailable, the system can immediately switch to the bypass channel without delay, thus improving reliability while managing complexity through proactive preparation
Solution Approach 2:
The gateway server acts as an intermediary that mediates between the merchant system and the payment network. It intelligently selects whether to route authorization requests through the acquirer processor or bypass it directly to the payment network, based on real-time availability detection. This intermediary function resolves the contradiction by adding routing intelligence that improves reliability without requiring complex changes to the underlying payment infrastructure
2Productivity
If a bypass communication channel is implemented to route authorization requests directly to the payment network, then transaction authorization can continue when the acquirer processor is unavailable, but the system complexity increases
Solution Approach 1:
The routing system is made dynamic by implementing real-time availability detection of the acquirer processor and adaptive channel selection. The gateway server continuously monitors the status of the first communication channel and dynamically switches between the standard routing path (through acquirer processor) and the bypass path (direct to payment network). This dynamic adaptation ensures transaction processing continuity while managing complexity through automated, real-time decision-making rather than static complex configurations
Solution Approach 2:
The system changes the routing parameter (communication channel selection) based on the availability status of the acquirer processor. When the acquirer processor is available, the system uses the first communication channel; when unavailable, it switches to the second communication channel. This parameter change approach allows the system to maintain productivity through flexible routing while keeping the underlying infrastructure relatively simple, as it only requires switching between predefined channels based on a binary availability condition

AI summary
Techniques are provided for fallback authorization routing. A merchant processor may receive authorization requests from one or more merchant systems. These authorization requests may be to authorize a transaction. The merchant processor may transmit these authorization requests over a first communication channel to an acquirer processor, which may then forward the requests to a payment network. If the merchant processor determines that the acquirer processor is not receiving the authorization requests, or is otherwise unavailable, the merchant processor may, as a fallback, transmit the authorization requests directly to the payment network through a second communication channel, thereby bypassing the acquirer processor. When the merchant processor receives some indication that the acquirer processor is available to process authorization requests, new authorization requests can be transmitted to the acquirer processor via the first communication channel.
