How APIs Enforce Consistent Data Validation
from The API Podcast with Fexingo: REST, GraphQL, and Modern Web APIs Hosted by Fexingo
Every API call carries data, and if that data isn't validated properly, it can lead to security holes, corrupted databases, and angry users. In this episode, Lucas and Luna dive into the often-overlooked world of API data validation. They explore how JSON Schema, OpenAPI, and tools like Ajv and Zod are changing the game, and why strict validation on the server side is your first line of defense against bad actors and accidental bugs. They also break down the difference between syntactic validation (is this a valid email?) and semantic validation (is this email allowed to sign up?), and share practical tips for returning helpful error messages without leaking internals. If you've ever wondered why some APIs return 400 errors with cryptic messages, or why your team keeps arguing about validation logic, this episode is for you. Plus, a quick look at how banks and airlines handle validation for high-stakes transactions, and how you can apply those patterns in your own API design. #APIDataValidation #JSONSchema #OpenAPI #Zod #Ajv #APIValidation #WebDevelopment #TechPodcast #APIsecurity #DeveloperTools #ValidationStrategy #ServerSideValidation #APIDesign #FexingoBusiness #BusinessPodcast #Technology #SoftwareEngineering #APIErrors Keep every episode free: buymeacoffee.com/fexingo
