Understanding JSON Schema for API Validation
JSON Schema is a powerful tool for validating the structure of JSON data. It allows you to describe the format, constraints, and relationships of your JSON instances, ensuring that data adheres to predefined rules. This is particularly useful in API development for both request and response validation, guaranteeing data integrity and consistency. By defining a schema, developers can automatically validate incoming payloads, provide clear error messages, and generate documentation. It supports various data types, arrays, objects, and complex conditional validations.
