Why Your API Should Version Its Errors
from The Developer Tools Podcast with Fexingo: APIs, Infrastructure, and Software for Engineers Hosted by Fexingo
In Episode 166 of The Developer Tools Podcast, Lucas and Luna dig into a problem every API team hits eventually: what happens when your error messages change. They trace a real-world example from a payments API that added a new validation rule and silently broke thousands of client integrations. They explain why error codes are contracts, how versioning errors differs from versioning endpoints, and why a simple field like `error_code` can save your developers from shipping bugs that take weeks to trace. They also talk about the risk of changing human-readable messages and how to deprecate old error codes without breaking the clients that still rely on them. If you've ever inherited a legacy API where the error responses are a mess, this episode gives you a practical framework for cleaning it up. #APIDesign #ErrorHandling #DeveloperExperience #TechLeadership #SoftwareEngineering #APICompatibility #ErrorCodes #BackwardCompatibility #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #DevTools #APIStrategy #ClientFacingAPIs #VersioningStrategy #DeveloperToolsPodcast #APIErrors #ContractDrivenDevelopment Keep every episode free: buymeacoffee.com/fexingo
