How to Design API Error Responses Your Developers Will Thank You For

Most API errors return a cryptic 500 or a vague 400, leaving developers to guess what went wrong. In Episode 17 of The API Podcast with Fexingo, Lucas and Luna dissect what makes an error response actually useful—using Stripe's structured error schema as the gold standard, then contrasting it with a real-world example from a major airline API that returns only 'Error: bad request.' They break down the three layers every good error should have: an HTTP status code that follows the spec, a machine-readable error type, and a human-readable message that tells you how to fix it. Luna shares a horror story about debugging a payment API that returned 'failure' for everything, and Lucas explains why adding an optional parameter for a list of validation errors can cut integration time in half. The episode closes with a practical checklist you can apply to any API you build or consume. Perfect for backend developers, API product managers, and anyone who has ever stared at a cryptic error message at 2 AM. #API #APIDesign #ErrorHandling #DeveloperExperience #RestAPI #GraphQL #HTTPStatusCodes #Stripe #WebDevelopment #Backend #APIBestPractices #Debugging #JSON #RESTful #APIErrors #TechPodcast #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
