Vault portability lets merchants move tokenized payment credentials to another vault provider without requiring cardholders to re-enter their card details.

Transaction decisioning is the real-time logic determining how each payment is routed, authenticated, retried, or declined based on live rules and data.

Composer is Spreedly's no-code workflow builder for configuring payment routing and recovery strategies without writing custom code for each scenario.

The orchestration layer sits between merchant systems and payment providers, managing routing, vaulting, and decisioning across all connected gateways.

Spreedly's Open Payments Platform provides one API to access gateways globally, with universal vaulting and intelligent routing built in from the start.

Gateway agnostic describes architecture not tied to a single gateway, letting merchants connect, switch, or add providers without re-engineering the stack.

Waterfall routing tries gateways in a defined priority sequence, moving to the next only when the previous one declines or returns an error response.

Least cost routing sends debit transactions to the lower-cost network on dual-network cards, reducing interchange and scheme fees on eligible transactions.

Revenue continuity is the operational goal of recovering recurring payment failures quickly to protect subscription revenue and minimize involuntary churn.

Authorization rate is the percentage of submitted transactions approved by the issuing bank, a core metric measuring payment system performance and health.

Card lifecycle management keeps stored credentials current by tracking expiry and replacements, preventing subscription and recurring billing failures.

Decline salvage retries a declined transaction through alternative gateways to recover revenue otherwise permanently lost to a single provider refusal.

A payment token is a non-sensitive reference for a real card number, enabling merchants to process future transactions without storing sensitive card data.

Network tokenization replaces a card PAN with a network-issued token with cryptographic data, improving authorization rates and automating card updates.

A payment vault stores tokenized credentials across gateways, giving merchants portability, reuse, and lifecycle management for stored payment methods.

A multi-gateway strategy connects a merchant to more than one gateway, enabling routing flexibility, redundancy, and authorization rate optimization.

Failover routing redirects a transaction to a backup gateway when the primary fails, ensuring payment continuity during outages or connectivity errors.

Intelligent routing uses data and machine learning to direct each payment to the optimal provider, maximizing approval rates and reducing processing costs.

Dynamic routing selects the best gateway for each transaction based on real-time authorization rates, cost, and latency, maximizing payment performance.

Embedded finance integrates financial services such as payments, lending, or insurance directly into non-financial software products and user experiences.

A core banking system is the central platform managing a financial institution's accounts, transactions, and ledger records across all its products.

Payment middleware sits between a merchant's systems and payment providers, managing data translation, routing logic, and connectivity across the stack.

A multi-rail strategy uses more than one payment network type to process transactions, improving resilience, market coverage, and overall cost efficiency.

ISO 20022 is the global financial messaging standard replacing legacy formats with structured XML data, improving processing efficiency and reconciliation.

A virtual IBAN (vIBAN) routes incoming payments to a master bank account via a unique identifier, enabling automated reconciliation without extra accounts.

An idempotency key is a unique request identifier ensuring that retrying a failed API call does not create a duplicate transaction in the payment system.

A sandbox is an isolated test environment simulating live payment processing, letting developers test integrations without processing real transactions.

A webhook is an HTTP callback a payment provider sends to a merchant's server when an event occurs, such as a successful authorization or completed refund.

Banking as a Service (BaaS) lets non-bank companies offer financial products by accessing a licensed bank's infrastructure and regulatory permissions.

White-label payments let a company offer processing services under its own brand, powered by a third-party provider's infrastructure and licensing.

Embedded payments integrate payment acceptance directly into a software platform so users can transact without leaving the application's interface.

A hosted payment page is a provider-managed checkout where cardholders enter card details, removing sensitive data from the merchant's own environment.

Payment rails are the infrastructure networks over which money moves, including card networks, ACH, wire transfers, and real-time payment systems.

A payment stack is the full set of technology and service providers a business uses to accept, route, settle, and reconcile payments across its channels.

A single API integration connects once to an orchestration platform, unlocking hundreds of gateways and payment methods without repeated re-integration.

An API lets software systems communicate, enabling merchants to connect payment services programmatically through a single integration point.

A Payments Orchestration Platform connects merchants to gateways and payment methods via one API, enabling routing, vaulting, and performance optimization.

Payment orchestration manages multiple providers through one layer to optimize authorization rates, reduce costs, and improve resilience across markets.

A PSP provides merchants with the full payment acceptance stack: gateway, acquiring, and settlement.

A payment gateway transmits payment data between a merchant's system and the acquiring bank for authorization.

An underwriter in payments assesses merchant applications, setting risk parameters, transaction limits, and reserve requirements for each new account.

A Wholesale ISO sits at the top of the reseller hierarchy, contracting directly with acquiring banks and managing a portfolio of smaller sub-ISOs.

An Ultimate Beneficial Owner (UBO) is the natural person who ultimately controls a legal entity, a core requirement in AML and KYB compliance programs.

A Third-Party Sender (TPS) submits ACH entries on behalf of originating companies, acting as a network intermediary with its own compliance obligations.

A referral partner sends merchants to a payment provider in exchange for a commission or residual revenue share on the volume they generate.

Payfac-as-a-Service lets platforms offer payment facilitation without becoming a full PayFac.

A sponsored merchant processes payments under a PayFac's master account rather than its own direct acquiring relationship with a card network.

A beneficial owner is any individual who ultimately owns or controls a business, typically at 25% or more, required for KYB and AML compliance.

A Master ISO recruits and manages a network of smaller ISOs and agents.

A Registered ISO is formally registered with a card network, allowing it to brand its products and contract directly with merchants and acquiring banks.

A payment processor handles technical routing between merchants, card networks, and issuing banks.

Card networks like Visa and Mastercard operate global infrastructure connecting issuers and acquirers, set rules, and process transactions between them.

An ISO resells payment processing on behalf of acquiring banks.

A merchant aggregator processes payments for multiple businesses under one account.

A PayFac enables other businesses to accept payments under its own master merchant account.

A cardholder is the individual authorized to use a payment card issued by a bank.

A sub-merchant accepts payments through a payment facilitator rather than a direct acquiring relationship.

An issuing bank provides payment cards and approves or declines transactions in real time.

An acquirer processes card payments for merchants and settles funds into their account.

A merchant is any business accepting card or electronic payments.
