The API Podcast with Fexingo: REST, GraphQL, and Modern Web APIs

About The API Podcast with Fexingo: REST, GraphQL, and Modern Web APIs

Every week, Lucas and Luna sit down at a developer-focused office workstation to trace how applications actually talk to each other — not the hype, but the design decisions, trade-offs, and real-world failures that shape modern API architecture. Lucas, with a journalist's precision, lays out why a team chose REST over GraphQL for a payments pipeline handling 50,000 requests per second, or how a poorly designed endpoint caused a cascade failure in a major ride-hailing service. Luna, the engaged interlocutor, pushes back: when does schema flexibility become a liability? How do versioning strategies survive a decade of production use? Together, they dissect public postmortems, API design docs, and developer surveys — not to sell a tool, but to understand the engineering logic behind each choice. This show is for backend engineers, API product managers, and technical leads who need to decide, not just follow the trend. Expect no demos, no code walkthroughs — just two smart people reasoning about trade-offs in stateless design, pagination patterns, rate-limiting, and the cost of backward compatibility. By the end of each episode, you'll have a clearer framework for your own decisions: Should your next endpoint be a query or a mutation? When does an SDK become a maintenance burden? And how do you design an API that your colleagues will still respect five years from now? #REST #GraphQL #WebAPIs #APIDesign #BackendEngineering #SoftwareArchitecture #APIVersioning #Microservices #HTTP #DeveloperTools #APIPostmortem #PlatformEngineering #Technology #FexingoBusiness #BusinessPodcast #Business #TechPodcast #SoftwareEngineering Keep every episode free: buymeacoffee.com/fexingo (https://buymeacoffee.com/fexingo)

   API Security Through Zero Trust Architecture

   We drill into how modern API security has shifted from perimeter defense to zero trust. Using the recent shift in cloud infrastructure standards, we explore why identity verification is now more critical than network firewalls. Lucas and Luna break down the mechanics of mutual TLS and token validation, showing how a single misconfigured endpoint can expose millions of user records. This episode offers a concrete look at implementing least-privilege access in high-volume systems. #ZeroTrust #APISecurity #MutualTLS #IdentityVerification #CloudSecurity #LeastPrivilege #TokenValidation #Cybersecurity #TechStrategy #DataProtection #NetworkArchitecture #FexingoBusiness #BusinessPodcast #TechNews #DigitalTransformation #InfoSec #WebDevelopment #EnterpriseTech Keep every episode free: buymeacoffee.com/fexingo (https://buymeacoffee.com/fexingo)

   API Design Costs Hidden in Legacy Code

   Legacy systems are not just old code; they are expensive architectural debt that drains engineering resources. In this episode, we examine how technical debt compounds interest rates through increased maintenance costs and slowed feature delivery. We look at the hidden overhead of maintaining backward compatibility in REST APIs versus the clean break offered by GraphQL migrations. The conversation explores why companies like Spotify and Netflix chose radical API evolution over incremental patching. You will learn how to calculate the true cost of a single deprecated endpoint and why treating API design as a product rather than a utility saves millions in operational expenses. #APIDesign #TechnicalDebt #RESTvsGraphQL #SoftwareEngineering #SystemArchitecture #DeveloperExperience #DigitalTransformation #TechLeadership #FexingoBusiness #BusinessPodcast #APIEconomics #CodeMaintenance #Microservices #EnterpriseTech #LucasAndLuna #TechStrategy #ModernWeb #BackendDevelopment Keep every episode free: buymeacoffee.com/fexingo (https://buymeacoffee.com/fexingo)

   Why Your API Docs Are Scaring Away Developers

   We dissect why technical documentation acts as the silent revenue killer for modern APIs, using Stripe and Twilio as contrasting benchmarks for developer experience. Today we explore how ambiguous error codes, missing authentication flows, and lack of code samples create friction that drives developers to competitors. We also look at the specific metric of 'time-to-first-call' and why your engineering team might be underestimating the cost of bad docs. This episode provides actionable steps for auditing your own API reference pages before they lose you enterprise contracts. #APIEconomics #DeveloperExperience #TechnicalDocumentation #Stripe #Twilio #ProductManagement #SaaSEconomics #IntegrationCosts #TimeToFirstCall #APIStrategy #SoftwareDevelopment #B2BSaaS #FexingoBusiness #BusinessPodcast #TechLeadership #CustomerAcquisition #EngineeringCulture #DigitalProducts Keep every episode free: buymeacoffee.com/fexingo (https://buymeacoffee.com/fexingo)
