Description: Payload validation is the process of verifying the data sent through an API or web service, ensuring that it is correct and secure before processing. This process is crucial in the context of web architectures and microservices, where data is transmitted over HTTP or HTTPS. Validation involves checking that the data meets expected formats, does not contain malicious information, and is consistent with defined business rules. Payload validation helps prevent application errors, injection attacks, and other security issues. Additionally, it contributes to data integrity and user experience by ensuring that only valid data is processed. In the field of data engineering, payload validation is essential to ensure that the data integrated into systems is accurate and useful. In summary, payload validation is a fundamental component in the development of modern applications, where data security and quality are paramount.
