Customize everything. Break nothing.
Before/after hooks around bid validation, increment logic, close mechanics, and settlement ensure that your custom bidding rules, buyer premium calculations, and operational workflows survive every platform upgrade.
The Problem
Auction operators who customize their platform discover that every modification blocks future updates, creating technical debt that compounds over time. Custom bidding rules represent years of operational refinement — losing them during an upgrade is unacceptable. Platform freezes result.
The Solution
AuctionFlow's extension model isolates custom logic in versioned hooks and policy overrides that execute at defined points in the auction lifecycle. Core platform updates bypass custom code entirely. Automated compatibility checking validates that custom extensions work with new platform versions before the upgrade completes.
Capabilities
Before/After Bid Validation Hooks
Inject custom logic before or after the core bid validation pipeline. Use cases include custom bidder qualification checks (membership verification, financial pre-approval), bid limits per bidder or per event, conditional bidding restrictions (time-based, geographic), and custom conflict resolution rules. Hook code executes in a sandboxed environment with access to the bid context and bidder profile.
Increment Logic Overrides
Override the default increment calculation with custom logic per lot category, value threshold, or auction type. A jewelry auction house might use AuctionFlow's standard increments for estate jewelry but apply a custom tiered increment table for fine diamonds. The override executes at the increment calculation point without modifying the core increment engine.
Close Mechanics Customization
Customize soft-close duration, extension behavior, and lot close sequencing through hooks around the close engine. Implement staggered closing across lot groups, variable extension durations based on active bidder count, or custom anti-sniping rules that go beyond the built-in soft-close logic.
Settlement Workflow Extensions
Add custom buyer premium calculations, payment routing rules, disbursement logic, and accounting sync behavior through settlement hooks. A tiered buyer premium based on hammer price, custom commission splits for multi-seller events, or charity lot handling with special tax documentation can all be implemented without touching the core settlement engine.
Policy-Driven Overrides
Express business rules as declarative policies evaluated at runtime rather than hard-coded modifications. Policies support conditional logic (if lot value > X, apply rule Y), composable conditions, and versioned activation. Policies are easier to review, test, and maintain than code-based customizations.
Architecture
The extension model uses a hook registry where custom extensions are registered at specific execution points in the auction lifecycle. Each extension carries version metadata and declares its compatibility range with the core platform. During upgrades, the system validates all registered extensions against the new platform version and reports any compatibility issues before the upgrade proceeds. Extensions that pass validation continue to execute at the same points in the updated platform.
AI Copilot
The AI copilot generates starter hook templates from plain-language rule descriptions, validates custom extensions for compatibility with the current platform version, identifies potential conflicts between multiple custom hooks, and assists with migration when a hook needs updating for a new platform version.
Before & After
Custom bidding rules break every time the platform updates
Custom hooks execute at defined points and survive all platform upgrades
Platform frozen at an old version because custom code cannot be migrated
Automated compatibility checking validates extensions before every upgrade
Business rules hard-coded into platform source, creating maintenance nightmares
Declarative policies express rules at runtime without code modification
Custom increment logic requires forking the core bidding engine
Increment overrides plug in at the calculation point without forking anything
