E-Commerce Integrations
Custom integration libraries for Shopify, WooCommerce, Etsy, and more — no third-party SDK wrappers, complete domain control.
We build fully custom integration libraries for the platforms that power modern e-commerce — no third-party SDK wrappers, no black boxes. Every integration is purpose-built for your domain, giving you complete control over performance, error handling, and business logic.
Our integrations power production workloads processing real orders daily across multiple sales channels simultaneously.
Multi-Channel Strategy
Selling on one platform is straightforward. Selling on three — with unified inventory, consistent pricing, and coordinated fulfillment — requires deep integration work. We build the connective tissue between your sales channels and your operations, so orders flow in from Shopify, WooCommerce, and Etsy and are processed through a single fulfillment pipeline.
- Unified order ingestion across all channels with duplicate detection and idempotent processing
- Bidirectional product synchronization — create products locally and push to all channels, or link existing remote products
- Per-channel credential management with automatic auth-health tracking and recovery
- Webhook-driven automation with real-time order, product, and fulfillment event processing
Shopify Integration
Our Shopify integration communicates directly with the Admin GraphQL API using a custom-built transport layer and a 47,000+ line strongly-typed C# schema. This gives us compile-time safety across the entire Shopify API surface — no magic strings, no runtime surprises.
What you get:
- Complete product lifecycle — creation, variant mapping, media upload pipelines with retry logic, and automatic storefront publishing
- Fulfillment order processing — accept fulfillment requests, create fulfillments with tracking, and manage inventory across locations
- Intelligent rate limiting — per-shop throttle management calibrated by real API responses, so you never hit Shopify's limits
- Full OAuth 2.0 — authorization, token management, HMAC webhook validation, and automatic reauthorization detection
- Webhook automation — idempotent event processing with advisory locks to prevent duplicate orders under concurrent delivery
WooCommerce Integration
Our WooCommerce integration is a custom REST client built for the WooCommerce REST API v3, with a dual-authentication strategy that transparently handles hosts that reject standard authorization headers — a common issue with shared hosting environments.
What you get:
- Resilient authentication — automatic fallback from Basic Auth to query-parameter credentials, with auth-health tracking that flags channels needing reauthorization
- Product synchronization — create variable products with full color/size attribute matrices, incremental variant sync, and SKU-based linking
- Webhook lifecycle management — automatic setup, legacy endpoint cleanup, per-topic deduplication, and environment-aware URL configuration
- Order processing — webhook-driven order creation with shipping calculation, tax handling, and tracking number posting back to WooCommerce
Etsy Integration
Our Etsy integration communicates with Etsy Open API v3 using a custom OAuth 2.0 PKCE client, paired with a ShipStation (ShipEngine v2) integration for shipping-label generation and rate calculation — required for fulfillment services that need access to buyer shipping addresses.
What you get:
- OAuth 2.0 with PKCE — secure authorization with automatic token refresh, expiry-skew detection, and refresh-token lifecycle management
- Receipt-driven order ingestion — receipt parsing with monetary conversion, address normalization, and payment verification
- Background synchronization — automated polling for new orders with concurrent channel processing and structured run summaries
- ShipStation label generation — multi-package rate calculation with carrier-specific handling (UPS multi-package vs. USPS per-package splitting)
- Image processing — automatic format conversion for Etsy compatibility with per-variant image assignment
Payment Processing
We integrate payment providers deeply into your order lifecycle — not just checkout, but wallet management, auto-pay, and financial ledger systems.
- Stripe — Embedded Checkout for seamless in-app payments, Payment Intents API for server-side capture, and webhook-driven confirmation
- PayPal — Orders API with server-side creation, capture, and redirect handling
- Merchant wallets — transaction-based ledger with credits, debits, manual adjustments, WIP tracking, and admin audit trail
Shipping & Fulfillment
End-to-end shipping integration from rate calculation through label creation to tracking-number propagation across all sales channels.
- ShipStation (ShipEngine v2) for multi-carrier label creation and rate comparison
- Category-based shipping groups for accurate cost calculation
- Tracking numbers flow automatically from production to Shopify, WooCommerce, Etsy, and merchant notifications
- Packing slip generation and fulfillment coordination tools
