WooCommerce webhook signature validation uses HMAC verification against the webhook secret. Compare the X-WC-Webhook-Signature header with a computed hash of the request body to ensure authenticity before processing events asynchronously.

Product variants in WooCommerce require fetching variation data through the `/variations` endpoint, mapping option IDs to attribute terms, and maintaining consistent serialization of variant metadata across requests to avoid conflicts and data loss.

WooCommerce OAuth 1.0a uses key pairs and HMAC-SHA256 signing over HTTPS. Generate consumer keys and secrets, plan for key rotation, verify API version compatibility, and detect plugin conflicts before deploying across staging and production environments.

Complex tax and shipping configurations are managed through tax rate and shipping zone endpoints. Paginate bulk operations, test in staging first, and use asynchronous webhooks to track state changes without blocking store performance.

Optimize performance using pagination and filtering for bulk product or order operations, implement asynchronous webhook processing instead of synchronous calls, and migrate from legacy composer patterns to static methods to reduce memory overhead in production.

Yes. WooCommerce requires explicit API version compatibility validation and plugin conflict detection during integration. Enforce these checks in development, staging, and production to prevent breaking changes and extension failures.
