Method Chaining Pitfalls & Alternatives
Method chaining (fluent interfaces) improves readability for builders but creates debugging difficulties, encourages temporal coupling, and can hide null returns.

Refactoring Boolean Flag Parameters
Boolean flags as function parameters obscure intent — replace with enums, separate functions, or named options objects for self-documenting APIs.

API Authentication Patterns
Bearer tokens (JWT) for user sessions, API keys for machine-to-machine, mTLS for highest-security internal services — matching authentication method to the use case.

Diagram: API Backwards Compatibility API Backwards Compatibility
Rules for evolving an API without breaking existing clients — additive changes are safe, removals and renames require versioning, and deprecation needs a documented sunset period.

API Composition Pattern
An API layer aggregates parallel service calls into a single client response — reducing N round trips to 1 and improving perceived latency.
2mo ago architecture advanced
API Contract Testing
Consumer-driven contract tests verify that a provider API matches what consumers expect — catching breaking changes before deployment, without end-to-end tests.

API Documentation
OpenAPI/Swagger for REST APIs, Postman collections for explorability, and Stoplight for design-first workflows — good API docs are the product's user interface for developers.

Diagram: API Idempotency Keys API Idempotency Keys PHP 7.0+
A client-generated unique key sent with non-idempotent requests — the server stores the response and returns it unchanged if the same key is received again, preventing duplicate operations.
2mo ago api_design intermediate
API Mocking
Prism (OpenAPI mock server), WireMock (HTTP stub server), Mockoon (GUI), and Guzzle MockHandler for PHP unit tests — enabling testing without real API calls.

Diagram: Backends for Frontends (BFF) Backends for Frontends (BFF) PHP 7.0+
A dedicated API layer per frontend client (mobile app, web app, third-party) — each BFF aggregates and transforms microservice data for its specific client's needs.
2mo ago architecture advanced
GraphQL vs REST vs gRPC
REST for public APIs and resource-oriented design, GraphQL for flexible client-driven queries, gRPC for high-performance internal service communication.

Hypermedia APIs — HATEOAS
REST APIs that include links in responses — clients discover available actions from the response rather than hardcoding URLs, making APIs self-describing and evolvable.
2mo ago api_design advanced
Open Host Service & Published Language
A bounded context exposing a well-defined protocol (Published Language) for all downstream consumers — rather than custom point-to-point integrations for each.
2mo ago architecture advanced
Webhook Design PHP 5.0+
Best practices for reliable webhooks — HMAC signature verification, idempotency, delivery retry with exponential backoff, and handling slow consumers with queues.
2mo ago api_design intermediate
Diagram: API Deprecation API Deprecation
The process of signalling that an API version, endpoint, or parameter will be removed — giving consumers time to migrate while maintaining backwards compatibility.
2mo ago api_design intermediate
Diagram: API Error Handling API Error Handling
Returning structured, machine-readable error responses using appropriate HTTP status codes — enabling clients to handle errors programmatically without parsing message strings.
2mo ago api_design intermediate
Diagram: API Pagination Patterns API Pagination Patterns
Strategies for returning large collections in manageable chunks — offset/page-based, cursor/keyset, and hybrid approaches each suit different use cases.
2mo ago api_design intermediate
Diagram: API Rate Limiting API Rate Limiting
Controlling how many requests a client can make in a time window — protecting against abuse, ensuring fair usage, and preventing accidental DoS from misbehaving clients.
2mo ago api_design intermediate
Boolean Parameters (Flag Arguments Smell)
A boolean parameter that switches a function between two different behaviours — a sign the function should be split into two.

Fluent Interface / Method Chaining PHP 5.0+
An API design style where methods return $this, enabling readable chains of calls that resemble natural language.
