Description: A Request Validation API is a programming interface that allows developers to verify that incoming requests to a system meet specific criteria before being processed. This validation can include checking data formats, user authentication, permission verification, and data integrity validation. By implementing this API, the goal is to ensure that only valid and secure requests are accepted, helping to prevent errors, fraud, and malicious attacks. Key features of a Request Validation API include its ability to handle different types of data, its flexibility to adapt to various business rules, and its integration with other systems and services. The relevance of this API lies in its crucial role in modern software architecture, where data security and quality are fundamental for the efficient operation of applications and services across various environments.
