Description: A token review is an API call to validate a bearer token. This process is fundamental in systems that implement authentication and authorization, as it allows verifying the validity of a token that has been previously issued. In the context of cloud-native environments and microservices architecture, token review is used to ensure that requests to APIs come from authenticated and authorized users or services. Token review involves checking the token’s signature, verifying its expiration date, and validating the permissions associated with it. This mechanism is essential for maintaining the security and integrity of distributed systems, ensuring that only authorized users and services can interact with sensitive resources. Additionally, token review integrates with identity and access systems, such as OAuth2 and OpenID Connect, allowing for more flexible and scalable management of authentication in diverse technology stacks.
