Implementing the Circuit Breaker Pattern for REST API Clients

Maxim Mironjuk - May 10, 2026

When an external REST API service responds slowly or fails completely without the client reacting, requests pile up, threads or workers block, and the outage spreads into your own application. The circuit breaker pattern breaks this chain by stopping calls to the failing service entirely after repeated failures and returning a fallback immediately instead.

OpenAPI vs. GraphQL: Where Both Models Complement Each Other

Maxim Mironjuk - April 25, 2026

The question isn't "OpenAPI or GraphQL?", it's "What is each model good for, and when does it make sense to run both in the same system?" Anyone who understands both models and their respective strengths makes better API architecture decisions.

API Platform and OpenAPI: What Is Automatically Good and What You Must Override

Maxim Mironjuk - April 15, 2026

API Platform generates OpenAPI documentation from PHP classes, which saves hours of manual work. But schema names with internal counters, missing examples, rudimentary security definitions and undocumented error cases show where the automation promise reaches its limits. This article shows concretely what works well, and what needs to be overridden.

Testing Magento REST Webapi Interface Contract Compliance

Maxim Mironjuk - April 11, 2026

Magento's REST API is built on service contracts declared in webapi.xml, yet nothing in day-to-day work prevents an implementation from silently drifting away from the declared interface over time. Automated contract compliance tests close exactly that gap.

Persisted Queries: Security and Performance in GraphQL

Maxim Mironjuk - April 07, 2026

Persisted Queries solve two problems at once: they reduce the amount of data transferred and close a security gap that is often overlooked in public GraphQL APIs. Anyone who accepts arbitrary queries hands attackers a free pass. Anyone who only allows known queries gains control, without sacrificing flexibility entirely.

Custom REST API Endpoint in Magento 2 | From webapi.xml to the Token

Maxim Mironjuk - April 05, 2026

A custom Magento 2 REST endpoint needs more than just a URL. What matters is a service contract, webapi.xml, ACL, clean dependency injection and a clear authentication strategy.

REST API Design: Cleanly Separating Resources, Verbs, Idempotency and Status Codes

Maxim Mironjuk - April 01, 2026

Many REST APIs use HTTP as a transport protocol without ever tapping into its semantics. Resources modeled incorrectly, verbs misused, idempotency not guaranteed and status codes chosen arbitrarily, these are not questions of style but design errors with direct consequences for caching, retry logic and client implementation.

Symfony Request DTOs and Response DTOs Instead of Arrays Everywhere

Maxim Mironjuk - March 29, 2026

Arrays as request and response data containers are the most common maintenance problem in Symfony REST APIs: no type safety, no autocompletion, no documentation generated from the code. PHP 8.4 readonly properties, the Symfony Serializer and the Symfony Validator turn DTOs into a clear upgrade, with less code, more safety and better IDE support.

Structuring OpenAPI YAML: components, Reuse, Naming and Versioning

Maxim Mironjuk - March 26, 2026

An unstructured OpenAPI specification turns into a maintenance burden the moment more than three developers work on it. With components/schemas, consistent $ref references and a clear versioning strategy, the API description stays the single source of truth for documentation, code generation and contract tests.

OpenAPI and Security Audits: What Auditors Really Want to See

Maxim Mironjuk - March 25, 2026

Security auditors open an OpenAPI document with a clear checklist in mind: are all endpoints authenticated? Are error responses fully documented? Is input validated? Whoever understands this perspective builds API documentation that speeds up audits, reduces findings, and builds trust.
