JWT

A compact, URL-safe standard (RFC 7519) for securely transmitting information (like user claims or authentication data) between parties as a JSON object. In digital marketing, JWTs enable secure API authentication for tools like ad platforms (e.g., Google Ads, Meta), single sign-on (SSO) in marketing dashboards, service accounts for automated reporting, or token-based access in custom integrations—ensuring marketers can pull data or trigger actions without exposing long-lived credentials.
