Fulfil is a cloud ERP and operations platform for e-commerce, DTC, and wholesale merchants - unifying order management, inventory, warehouse operations (WMS), manufacturing and production (MRP), purchasing, and accounting in one system, purpose-built for Shopify Plus and high-volume DTC brands. The Fulfil REST API (v2) exposes every ERP model through a single uniform model interface at https://{merchant_id}.fulfil.io/api/v2, advertising 6,000+ endpoints with full create/read/update/delete access, action calls, reports, and wizards across all models. Authentication is via OAuth 2.0 for public apps or personal access tokens (X-API-KEY / HTTP Basic) for private integrations, and outbound webhooks (with a Google Pub/Sub option) deliver real-time ERP events such as order and shipment changes.
