Implements secure webhook endpoints for Exa with signature validation and idempotent event handling.
This skill provides a standardized approach to implementing and securing Exa webhook notifications in your applications. It includes production-grade patterns for cryptographic signature verification using HMAC-SHA256, replay attack prevention via timestamp checking, and structured event dispatching. By utilizing this skill, developers can quickly set up reliable endpoints that handle Exa resource updates, creations, or deletions while maintaining strict security standards and ensuring data integrity through idempotency patterns.
