Prompt Caching
API feature where a static prompt prefix (system instructions, large context) is cached server-side, dramatically reducing cost and latency on repeated calls that share the prefix.

Fetch API
ES2015
1
The browser-native Promise-based API for making HTTP requests — replacing XMLHttpRequest with a cleaner interface supporting streaming, CORS, and request/response objects.

JavaScript beginner
OAuth 2.0
An authorisation framework that lets users grant third-party applications limited access to their resources without sharing passwords — using short-lived access tokens issued via defined flows for different client types.
CWE-287 OWASP A7:2021

Security intermediate
HTTP Content Negotiation
1
The HTTP mechanism by which clients declare what formats, languages, and encodings they accept (Accept, Accept-Language, Accept-Encoding) and servers respond with the best match — or 406 Not Acceptable if none fits.

API Design intermediate
GraphQL Subscriptions
A GraphQL operation type that opens a long-lived connection to the server and pushes real-time data updates to the client whenever a specific event occurs.

API Design advanced
CORS — Cross-Origin Resource Sharing
PHP 7.0+
A browser security mechanism that blocks JavaScript from making HTTP requests to a different origin — PHP APIs must send specific headers to allow cross-origin requests from permitted frontend origins.

Security intermediate
Guzzle HTTP Client
PHP 7.2+
Guzzle is PHP's most popular HTTP client library — providing a clean API for making synchronous and asynchronous HTTP requests, handling middleware, retries, authentication, and multipart uploads, with PSR-7 and PSR-18 compliance.

PHP intermediate
API Abuse Prevention
PHP 5.0+ Techniques to detect and block bots, scrapers, credential stuffing, and automated abuse — beyond basic rate limiting to behavioural and intelligence-based controls.

Security advanced
API Key Lifecycle Management
4
Generating, distributing, rotating, and revoking API keys securely — covering scoping, expiry, audit logging, and emergency revocation procedures.

Security intermediate
GraphQL Security
PHP 7.0+
GraphQL's flexibility creates unique security challenges — introspection exposure, unbounded query depth, N+1 amplification, and injection through dynamic resolvers.
3mo ago
Security advanced
API Design Principles
3
Guidelines for designing interfaces — method signatures, HTTP endpoints, error responses — that are intuitive, consistent, and evolvable.
3mo ago
Architecture intermediate
API Gateway Pattern
5
A single entry point for all clients that handles routing, authentication, rate limiting, and protocol translation for backend services.
3mo ago
Architecture intermediate
Consumer-Driven Contract Testing
1
A testing approach where the consumer of an API defines a contract of what it expects, and the provider verifies it satisfies that contract — enabling independent deployment of microservices.
3mo ago
Testing advanced
CORS
PHP 5.0+ Cross-Origin Resource Sharing — the browser mechanism that controls which cross-origin requests are permitted, using HTTP headers negotiated between client and server.
3mo ago
Networking intermediate
CORS Misconfiguration
PHP 5.0+
Overly permissive Cross-Origin Resource Sharing headers allow malicious sites to read sensitive API responses.
CWE-942 OWASP A5:2021

7.5
GraphQL
PHP 7.0+
1
A query language for APIs where clients specify exactly the data they need, reducing over-fetching and under-fetching versus REST.
3mo ago
Architecture intermediate
gRPC
PHP 7.0+
1
A high-performance RPC framework using Protocol Buffers and HTTP/2 — strongly typed contracts, efficient binary serialisation, and streaming support.
3mo ago
Architecture advanced
HTTP Status Codes
Three-digit codes in HTTP responses that indicate whether a request succeeded, failed, or requires further action.

Networking beginner
Idempotency
An operation is idempotent if performing it multiple times produces the same result as performing it once — essential for safe retries.

General intermediate
JWT Deep Dive
PHP 7.0+
JSON Web Tokens carry signed (or encrypted) claims — three Base64url-encoded sections: header.payload.signature. Security depends entirely on algorithm choice and verification correctness.
