概覽
Transaction rules represent the logic layer within a payment gateway or orchestration platform that governs the lifecycle of an individual payment request. By applying conditional statements to inbound data, these rules determine the path of a transaction before it reaches the acquirer.
Logic is typically structured using attributes such as the Bank Identification Number (BIN), Merchant Category Code (MCC), or geographical metadata. This mechanism allows a merchant to manage risk profiles and cost structures in real time.
Rather than treating all traffic as uniform, rules enable the segmentation of payments by risk level, value, or origin. This ensures that high-value transactions may require more stringent verification like SCA, while low-friction paths are maintained for low-risk scenarios.
This granularity is essential for businesses operating across multiple jurisdictions where local regulations and scheme rules vary. Effective rule implementation focuses on balancing fraud prevention with the preservation of authorisation rates.
運作方式
Attribute extraction and identification
When a customer initiates a payment at the checkout, the system identifies specific metadata associated with the request. This includes the card issuer country, the specific BIN, the currency, and the Merchant Identification Number.
These variables serve as the foundational data points upon which subsequent logic is applied.
Application of conditional logic
The transaction passes through a sequence of pre-defined 'if-then' statements. For example, a rule might specify that if a transaction exceeds a certain value and originates from a high-risk region, it must be diverted.
This stage determines the immediate fate of the payment before any network calls occur.
Fraud and authentication filtering
Based on the internal logic, the system decides whether to trigger Strong Customer Authentication via 3DS.
Rules can be configured to request 3DS only when risk thresholds are met, thereby reducing friction for low-value or trusted payments while maintaining compliance with relevant PSD2 or regional regulations.
Direction to optimal gateway
Once the transaction is validated, the rules engine chooses the most appropriate acquirer. This decision may be based on the lowest interchange-plus costs, the highest historical authorisation rates for the specific card type, or the need to meet volume commitments stipulated in merchant service agreements.
Authorisation and response handling
The request is transmitted to the selected acquirer. Upon receiving a response, the rules engine can interpret decline codes.
If a soft decline occurs, the system may initiate an automated retry through a different route, provided the merchant's ruleset permits subsequent attempts for that specific failure reason.
為何重要
Authorisation rate optimisation
Static routing often results in unnecessary declines due to regional card preferences or issuer-specific inconsistencies. By using rules to match transactions with the acquirer most likely to approve them, a merchant can increase successful captures.
This involves categorising transactions into groups that align with the strengths of different processing partners, ensuring that technical or risk-based refusals are minimised across the entire portfolio.
Mitigation of processing costs
Payment costs are rarely uniform across different card schemes or regions. Transaction rules allow for the prioritisation of routes with lower scheme fees or interchange costs.
By identifying local cards and routing them through domestic acquirers, businesses avoid the higher costs associated with cross-border processing. This systematic approach ensures that the most cost-effective path is chosen for every individual line item processed by the gateway.
Compliance and risk management
Regulatory environments like PSD2 require specific authentication behaviours. Transaction rules provide the mechanism to enforce these requirements without applying them universally.
Merchants can automate the exclusion of specific high-risk jurisdictions or restrict certain MCCs if they fall outside of risk appetite. This reduces the burden on manual review teams and protects the merchant from excessive chargeback rates or potential penalties from card schemes.
應用案例
Cross-border retail
A merchant selling globally can use rules to route payments through local acquirers in the European Union to capitalise on lower interchange rates, while using a different partner for North American traffic to optimise authorisation.
SCA exemptions
A subscription service can apply rules that automatically request exemptions for low-value recurring transactions, ensuring that customers are not interrupted by unnecessary 3-D Secure challenges that could lead to churn.
High-risk mitigation
An electronics retailer can implement rules that trigger 3DS for all first-time buyers whose shipping and billing addresses do not match, while allowing returning customers to proceed through a faster checkout.
Cost-based routing
A high-volume airline can direct all premium card transactions to a specific provider with a better blended-pricing structure for corporate cards, reducing the total fee burden on high-interchange payments.

Questions about 交易規則
支付處理中的交易規則是什麼？
交易規則是預定義的條件，決定如何處理個人支付嘗試。 它們讓商戶可以根據各種屬性自動決定接受、拒絕或路由交易，從而有效地優化支付流程和管理風險。
交易規則如何提高轉換率？
透過應用智能交易規則，商戶可以優化支付路由，將支付轉發給對特定交易類型或地理區域具有更高成功率的收單方。 他們還可以選擇性地應用 3DS，減少低風險交易的摩擦並提高整體轉換率。
交易規則是否可以與其他風險工具結合使用？
是的，Cardflo 的交易規則旨在與速度規則和風險評分等其他風險工具無縫集成。 這種組合允許建立多層次的欺詐預防策略，其中決策是根據對所有相關因素的全面評估而做出的。
Is it possible to route transactions based on the cost of processing?
Merchants can use rules to direct transactions to whichever acquirer offers the best pricing for that specific card type.
For example, if one acquirer has a better rate for commercial cards, the rules engine can identify the card type via the BIN and route the transaction accordingly. This ensures that the merchant is not overpaying for interchange-plus or scheme fees on high-cost transactions.
Can I set different rules for recurring payments versus one-off transactions?
Payment systems distinguish between Merchant Initiated Transactions and Customer Initiated Transactions. Rules can be configured to apply different risk filters to these categories.
Typically, a CIT might require 3DS for the initial setup, while subsequent MITs are permitted through the ruleset without further customer intervention, provided the appropriate tokens and indicators are present in the request.
How does BIN-based routing work in a transaction ruleset?
BIN routing uses the first six to eight digits of a card number to identify the issuer and card product type. Rules are set to recognise these digits and apply specific logic.
For instance, a merchant might route all 'Gold' or 'Platinum' cards to an acquirer with higher approval thresholds for premium cards, or route all domestic debit cards to a local provider.
