Description: A Token Validation API is a service that allows for the verification of the authenticity and validity of tokens used in authentication processes. These tokens are strings of characters that act as temporary credentials, allowing users to access protected resources without needing to send their username and password with each request. The API is responsible for validating these tokens, ensuring they have not expired, that they are legitimate, and that they correspond to an authorized user. Key features of a Token Validation API include the ability to handle different types of tokens, such as JWT (JSON Web Tokens) and OAuth, as well as the implementation of security measures to protect sensitive information. The relevance of these APIs lies in their fundamental role in the security of web and mobile applications, where authentication and authorization are crucial for protecting data and resources. By using a Token Validation API, developers can simplify session management and enhance user experience while reinforcing the security of their applications.
