JSON Web Tokens in Email Integrations: Secure App-to-App Identity

JWTs help services authenticate requests between systems for webhooks, sync, and APIs.

JSON Web Tokens (JWTs) are often used to secure API calls and webhook payloads between systems. They can prove the identity of a caller and prevent tampering if implemented properly. For email automation platforms, JWT-based verification helps ensure that CRM updates, tracking events, and sync actions are coming from trusted sources. The key is correct signing, expiration, and rotation practices.
