Webhook Signature Verification
Verify incoming webhook signatures using HMAC to ensure requests are authentic and untampered.
이 레시피 활용 시점
Services like Stripe, GitHub, and Slack sign webhook payloads with HMAC. Verifying these signatures prevents spoofed webhook attacks and ensures data integrity.

자주 묻는 질문
Why use HMAC for webhook verification?
HMAC ensures two things: the request came from the legitimate sender (authentication) and the payload wasn't modified in transit (integrity). Simple API keys only provide authentication.
What happens if I don't verify webhooks?
An attacker could send fake webhook events to your endpoint — triggering unauthorized actions like refunds, account changes, or data modifications.
