How APIs Handle Backward Compatibility Without Version Bumps

In this milestone 50th episode, Lucas and Luna dive into how modern API teams are moving away from explicit versioning in favor of backward-compatible evolution. They examine a real-world case: how a major payment processor—think Stripe-level scale—added a new required field to an existing endpoint without bumping the version number or breaking existing integrations. The conversation covers the three technical pillars that make this possible: additive-only changes, tolerance for unknown fields, and the use of `X-Forwarded-Compatibility` headers. Listeners will learn the concrete patterns that let APIs evolve continuously, and why 'never versioning' is becoming the gold standard for platform teams. #API #BackwardCompatibility #NeverVersioning #APIEvolution #AdditiveChanges #Stripe #PaymentProcessor #WebAPI #REST #GraphQL #OpenAPI #CompatibilityHeaders #DeveloperExperience #PlatformEngineering #Technology #TechPodcast #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
