Abstract
In the evolving landscape of digital commerce, transaction routing is increasingly dictated by intelligence at the orchestration layer. At Ottu, we’ve always believed in empowering merchants with tools that go beyond basic processing, enabling them to optimize, adapt, and lead. This article introduces ConstraintSense, Ottu’s new AI-powered routing engine, and outlines how data-driven decisioning, multi-stage routing, and machine learning (ML) are reshaping payment optimization strategies for global merchants.
1. Introduction
While connecting to multiple Banks, gateways, payment services and PSPs is a baseline requirement for modern merchants, orchestrating between them effectively has emerged as an important success factor. Static routing logic is no longer sufficient in a market defined by fluctuating authorizations, regional inconsistencies, and cost pressures.
To address this, Ottu has developed ConstraintSense, a dynamic routing engine that operates at the intersection of real time performance metrics, merchant defined constraints, and machine learning, transforming payment routing into an adaptive, intelligent process.
2. Context Aware Decisioning
The ConstraintSense Engine isn’t just about routing transactions; it’s about understanding context and making decisions based on a multitude of live signals. Built with AI/ML algorithms, the engine calculates dynamic weights and success probabilities for each available payment processor or channel, adapting in real-time based on:
- Historical success rates per acquirer and region
- Card BIN intelligence and issuer-specific behavior
- Transactional parameters (e.g., currency, value, timing)
- Exchange rate conditions and associated costs
- PSP traffic capacity and known disruption patterns
- Merchant priorities such as success rate maximization, cost optimization, or money traffic minimization
Using these signals, the engine computes weighted scores for available channels and selects the most appropriate processor, not merely the fastest or cheapest.
3. Multi Step Routing Lifecycle
Unlike traditional systems that make routing decisions only after card input, ConstraintSense operates across two main stages:
3.1 Pre-Display Routing
Determines the most viable PSPs before presenting payment options to the user. This ensures regional performance, success rate history, and strategic goals are reflected early.
3.2 Post-Card Input Routing
Performs a deeper evaluation post card entry. Here, processor-specific rules, fraud insights, and authorization likelihood shape the final decision to maximize transaction acceptance.
4. Built for Global Scale Merchants
For merchants operating across multiple countries, the engine delivers significant strategic advantages:
- Localized strategy execution per region or currency
- Real-time exchange rate and cost-aware routing
- Compliance with local mandates without code changes
- Built-in failover mechanisms to handle local disruptions
More importantly, it abstracts the complexity, letting merchants focus on growth while Ottu handles the orchestration behind the scenes.
5. ML Driven Optimization
At its core, ConstraintSense is a self-optimizing system. ML algorithms continuously update routing weights based on observed patterns. For example:
- Rebalancing based on peak/off-peak processor performance
- Reacting to changes in issuer acceptance behavior
- Detecting gradual degradation in authorization rates and triggering adaptive rerouting
This enables proactive improvement on routing logic without manual rule updates, transforming the engine into a living layer of intelligence.
6. Insights and Routing Timeline
Transparency and traceability are key to enterprise trust. With ConstraintSense, every routing decision is logged, forming a Routing Timeline for each transaction.
This timeline provides:
- A historical record of evaluated processors and their weights
- The rationale behind each routing choice
- Insight into real-time decisioning under constraints
Merchants can review and fine-tune strategies based on these insights. More importantly, this enables ongoing refinement, where routing preferences, AI weights, and business rules evolve iteratively through collaboration with Ottu’s teams or automated ML feedback loops.
7. Real World Merchant Impact
By using this new payment selection engine, merchants achieve:
- Higher authorization rates, particularly in geographies with variable payment services behavior
- Reduced operational costs, through cost aware and Traffic aware routing and automated fallbacks
- Improved end user experience, with fewer failed payments and retries
- Audit ready insight, ideal for finance and compliance teams
Combined with Ottu’s modular infrastructure and unified reporting, ConstraintSense becomes more than a feature, it is a strategic enabler.
Conclusion — Routing Smarter
The fintech domain is rapidly transitioning from toolsets to intelligent ecosystems. ConstraintSense represents Ottu’s commitment to intelligent orchestration, empowering merchants to move beyond transactions and drive sustainable growth.
As transaction volumes, regional fragmentation, and customer expectations grow, context aware, ML enhanced routing will become the standard, not the exception.
Let’s route smarter.
