Build anything on AuctionFlow.
Complete API-first architecture with REST, GraphQL, and WebSocket endpoints for auctions, lots, bids, bidder profiles, settlement, and reporting — plus webhook events for every auction lifecycle milestone.
The Problem
Locked-in platform UIs limit the bidder experiences operators can create. Integrating with existing business systems requires manual data synchronization or brittle custom connectors. Polling for auction updates is inefficient and introduces latency.
The Solution
AuctionFlow provides comprehensive REST and GraphQL APIs for all auction operations, WebSocket connections for real-time updates, and webhook events for lifecycle integration. SDKs are available for Node.js, Python, Ruby, and Go.
Capabilities
REST and GraphQL APIs
Full CRUD APIs for auctions, lots, bids, bidder profiles, settlement, invoices, and administrative configuration. REST endpoints follow standard patterns for predictable integration. GraphQL enables flexible querying for frontend applications that need specific data shapes without over-fetching.
Real-Time WebSocket Streaming
Persistent WebSocket connections deliver real-time bid updates, lot status changes, and auction lifecycle events to connected clients. Custom bidder frontends subscribe to specific lots or auctions and receive instant push notifications without polling, enabling responsive bid interfaces with sub-second latency.
Webhook Event System
Configurable webhook endpoints fire on every significant auction event: auction.created, lot.published, bid.placed, bid.proxy_activated, lot.closed, settlement.ready, payment.received, and more. Webhooks include retry logic with exponential backoff and failure alerting for reliable event-driven integrations.
OAuth 2.0 Authentication
API access is secured via OAuth 2.0 with support for client credentials (server-to-server), authorization code (user-delegated), and API key (simple integrations) grant types. Rate limiting and usage tracking protect API resources and provide visibility into integration consumption patterns.
SDKs and Developer Documentation
Official SDKs for Node.js, Python, Ruby, and Go accelerate integration development with type-safe client libraries, built-in authentication handling, and error management. Interactive API documentation with code examples, request/response schemas, and a sandbox environment enable rapid developer onboarding.
Architecture
The API layer is the same interface used by AuctionFlow's own frontend application, ensuring API parity with the built-in UI. Every feature available in the dashboard is accessible programmatically. API versioning follows semantic versioning with deprecation notices and migration guides for breaking changes.
AI Copilot
The AI copilot generates integration field mappings between AuctionFlow APIs and target systems (CRM, ERP, payment gateways), produces API integration code templates in the developer's preferred language, and validates webhook configurations for completeness and reliability.
