The Architecture of Professional REST APIs

<p>Your connection drops mid-checkout on a $1,000 ticket. Do you hit refresh and risk paying twice? The answer lives in the invisible architecture of REST APIs. In this deep dive we go from the basic grammar of the web to the patterns that keep global platforms fast, safe and reliable.</p><p><br /></p><p>You'll learn:</p><p>- What REST really is, and why verbs never belong in your URLs</p><p>- Resource naming, the two-level nesting rule, and when to flatten</p><p>- Honest HTTP status codes and error responses with trace IDs</p><p>- API versioning: URI vs headers vs content negotiation</p><p>- Why offset pagination breaks at scale, and how cursors fix it</p><p>- Safe vs idempotent methods, and how idempotency keys prevent double charges</p><p>- Authentication vs authorization, OAuth 2.0, and the trade-offs of JWTs</p><p>- ETags, sparse fieldsets, compression and 202 Accepted for long-running jobs</p><p>- Rate-limit headers and the token bucket algorithm</p><p>- The Richardson Maturity Model, HATEOAS, and API governance with OpenAPI</p><p><br /></p><p>Chapters</p><p>00:00 The $1,000 refresh dilemma</p><p>00:45 "It works" vs "it's designed well"</p><p>01:31 What REST really is</p><p>02:17 Resources: nouns and verbs</p><p>03:04 REST vs RPC</p><p>03:52 Nesting and flattening resources</p><p>05:28 Honest status codes</p><p>06:16 The status code vocabulary</p><p>08:36 Error responses that help you fix things</p><p>10:10 API versioning strategies</p><p>11:44 Why offset pagination breaks</p><p>12:53 Cursor-based pagination</p><p>14:03 Securing filters</p><p>14:38 Safe and idempotent methods</p><p>16:02 Idempotency keys</p><p>16:50 Authentication vs authorization</p><p>17:37 JWT trade-offs</p><p>19:11 Caching with ETags</p><p>20:22 Sparse fieldsets and compression</p><p>21:08 Long-running jobs with 202 Accepted</p><p>21:31 Rate-limit headers</p><p>22:16 Rate-limiting algorithms</p><p>23:28 The Richardson Maturity Model</p><p>24:14 HATEOAS in theory and practice</p><p>25:24 API governance</p><p>26:35 Three golden rules</p><p>27:22 Final thought</p><p><br /></p><p>#RESTAPI #APIDesign #BackendEngineering #SoftwareArchitecture #SystemDesign #InterviewPrep</p><p><br /></p><p>Interview Prep Podcast</p>
