Enable API Access with Minimal Setup

To integrate WooCommerce with external systems without coding, first configure WordPress permalinks to a human-readable format like 'Day and name' under Settings > Permalinks—avoid 'Plain' to prevent routing issues. This ensures API endpoints resolve correctly, allowing services to pull data like orders.

Next, generate API keys tied to a specific WordPress user: navigate to WooCommerce > Settings > Advanced > REST API, add a key with read/write permissions as needed, and copy the consumer key/secret. These credentials grant controlled access, making integration as simple as pasting them into third-party tools.

This approach lets non-developers connect to services quickly, while developers can test endpoints like fetching orders via basic GET requests.

Handle Legacy API for Existing Integrations

WooCommerce now uses the WordPress REST API natively, deprecating the old version—webhooks and integrations relying on it will fail without intervention. Install the free WooCommerce Legacy REST API plugin from WordPress.org, activate it, then enable under WooCommerce > Settings > Advanced > Legacy API.

Trade-off: Legacy support adds a dependency but preserves compatibility for older tools until migration. New builds should use the modern WordPress-integrated API for better alignment with WordPress ecosystem.

Validate and Extend with Docs

Test setup by following developer guides: make a basic request to retrieve orders, confirming keys work. Full reference at WooCommerce REST API Docs covers endpoints for products, customers, and more. For issues, search WordPress.org WooCommerce forums before posting—community resolves most queries.

This merchant-focused process prioritizes speed over depth, linking to GitHub technical docs for advanced use like custom endpoints.
