Full commerce capability accessible via documented, versioned APIs.
Every function available in the turnkey UI is also available through a complete set of APIs — catalog, pricing, inventory, cart, checkout, orders, customers, and content — with ERP-native authority behind every endpoint.
The Problem This Solves
Before CommerceWeave
When a team needs to embed commerce in a mobile app, kiosk, or custom frontend, they are forced to build a custom API layer from scratch or accept a shallow integration that cannot serve ERP-accurate pricing and inventory. Neither option is sustainable at scale.
With CommerceWeave
A documented, versioned API set covers the full commerce lifecycle with ERP-native data behind every endpoint. Development teams can build any commerce surface they need — mobile apps, kiosks, partner portals — without rebuilding the integration layer.
How It Works
Commerce APIs with ERP Authority
The CommerceWeave Commerce API set covers catalog (products, categories, attributes, facets), pricing (customer-specific, volume tiers, promotions), inventory (by warehouse/branch, real-time availability), cart (line items, pricing resolution, promotions), checkout (address validation, shipping rates, payment processing, order submission), orders (order history, status, line items), customers (account profile, addresses, payment methods), and content blocks (CMS-style content served via API for headless frontends). Each endpoint that returns pricing or inventory data resolves its values from the ERP in real time — not from a cached or replicated data store. This means a mobile app built on the CommerceWeave API serves the same ERP-accurate pricing and inventory as the full storefront UI.
Event and Webhook Model
Beyond request-response APIs, CommerceWeave exposes an event model that enables downstream automation based on commerce activity. Subscribable events include order created, order status changed, inventory level changed, price update, customer created, and approval workflow state changes. Each event delivers a structured payload to a configured webhook endpoint, enabling integration with CRM platforms, ERP workflow triggers, notification services, and analytics pipelines. The event model is used by implementation teams to build ERP writeback workflows — for example, when an order is placed in the storefront, an event triggers the ERP order creation process and returns the ERP order number to the storefront for display in the portal.
Admin APIs for Programmatic Configuration
Everything configurable in the CommerceWeave admin interface is also accessible via Admin APIs. This includes workflow configuration, user management, role assignments, extension registration, analytics event configuration, and content block management. Admin APIs enable CI/CD integration, infrastructure-as-code approaches to commerce configuration, and multi-environment promotion of settings from staging to production. Organizations managing multiple branded storefronts or multiple entity deployments use the Admin API to apply configuration changes consistently across all instances without manual repetition.
Architecture & Integration Notes
All APIs use REST with JSON response payloads. Authentication uses OAuth 2.0 bearer tokens with configurable scope-based access control. Rate limiting is applied per API key with burst allowances for high-traffic events. API versioning uses URI path versioning (/v1/, /v2/) with deprecation notice periods before breaking changes. The API gateway logs all requests with latency, response codes, and payload metadata for monitoring and debugging.
AI Copilot for Headless Commerce APIs
The AI copilot generates API integration code samples for common patterns — product listing, cart management, checkout flow — using the specific ERP and frontend framework in scope. It validates API credential configuration, tests endpoint connectivity during integration setup, and generates test scenarios that cover edge cases such as out-of-stock conditions, expired contracts, and approval workflow triggers.
AI Copilot — Available on Growth & Enterprise Plans
AI Copilot reduces implementation time for headless commerce apis by automatically generating field mappings, test datasets, and validation scripts based on your ERP schema — so your team can ship faster without writing repetitive configuration code.

Before & After CommerceWeave
| Area | Before | After CommerceWeave |
|---|---|---|
| Area 1 | Embedding commerce in a mobile app requires building a custom API layer from scratch | Full commerce APIs ready for any surface with ERP-native data behind every endpoint |
| Area 2 | Mobile apps and kiosks show cached pricing that drifts from ERP | Every API call resolves pricing and inventory directly from ERP in real time |
| Area 3 | Downstream automation requires polling or custom webhook infrastructure | Event model delivers structured payloads to webhooks for any commerce event |
| Area 4 | Configuration changes must be made manually across multiple environments | Admin APIs enable programmatic configuration management and environment promotion |
