They get into the specifics: why Stripe's new fee structure rewards high-volume users, the hidden costs of a free tier that shows up in your support queue, and how…
Why Your API Should Use Delta Snapshots
In this episode, Lucas and Luna explore why delta snapshots—sending only the changes since the last sync—are becoming a crucial pattern for API design, especially for mobile and IoT clients. They break down how delta snapshots differ from full and delta webhooks, using the example of a weather app to illustrate bandwidth savings, and discuss trade-offs like tombstone handling and client complexity. The hosts also cover practical implementation tips, including sequence numbers, filtering, and…
Why Your API Should Use Delta Encryption
Every webhook you ship is a plaintext postcard. In this episode, Lucas and Luna dig into delta encryption — the practice of encrypting individual fields or events in your API payloads rather than wrapping the whole thing in TLS and calling it a day. They walk through a real example: a fintech that accidentally leaked customer names because their webhook payloads were signed but not encrypted. They explain how envelope encryption works, why it matters for compliance, and where it fits alongside…
Why API Versioning Should Be Semantic
In Episode 169 of The Developer Tools Podcast, Lucas and Luna dive into the messy reality of API versioning. Most teams bolt on version numbers without a strategy, and developers pay the price. This episode unpacks why semantic versioning — the same major.minor.patch system that governs open-source libraries — is the right framework for HTTP APIs. Lucas walks through real-world examples like Stripe and Twilio, explaining how breaking changes should map to major versions, additive changes to…
