About the Backend & API Development Professional certification
The Backend & API Development Professional certification validates that you can design, build, secure and operate the server-side systems that power modern applications. It goes far beyond writing endpoints: you will reason about the HTTP protocol in depth (methods, status codes, headers, caching, content negotiation), design REST APIs that are consistent, versioned, paginated and idempotent, and know when GraphQL or gRPC fit better. The exam covers authentication and authorization end to end — sessions, JWT, OAuth2, OIDC, API keys and RBAC — plus input validation, serialization and the OWASP API Security Top 10. It tests real backend depth in databases (relational design, indexing, transactions and isolation levels, connection pooling, ORMs, the N+1 problem, migrations) and NoSQL (document, key-value and wide-column stores and when each fits), caching strategies and invalidation, message queues and asynchronous processing, concurrency and async I/O, and resilience patterns (timeouts, retries with backoff, circuit breakers, rate limiting). Finally it validates the operational craft that separates a hobby project from a service: observability (logging, metrics, tracing), testing (unit, integration, contract), the twelve-factor app, configuration and environments, webhooks and events, file/blob handling, internationalization, performance and scaling, and deployment basics. The content is language-agnostic — the principles transfer across Node.js, Python, Go, Java, Ruby, PHP and .NET. Candidates should already be comfortable with general programming and data structures.
What you will learn
The official Backend & API Development Professional study course covers:
- HTTP & the Request Lifecycle — How an HTTP request travels through a backend, plus methods, status codes, headers and caching.
- Designing REST APIs (and when not to) — Resource modeling, versioning, pagination, idempotency, and choosing REST vs GraphQL vs gRPC.
- Authentication & Authorization — Sessions, JWT, OAuth2/OIDC, API keys, RBAC, and the access-control bugs that matter.
- Data & Persistence — Relational design and indexing, transactions and isolation, ORMs and the N+1 trap, and choosing SQL vs NoSQL.
- Caching & Asynchronous Processing — Cache layers and invalidation, message queues and workers, idempotency and async I/O.
- Resilience, Security & Operations — Timeouts, retries and circuit breakers, rate limiting, observability, API security and deployment.
