Resources, commands, events, errors and compatibility.
Systems that cooperate
PHP APIs and integrations with dependable contracts and operations
We design cross-system flows for errors, duplicates, retries, traceability, security and contract evolution—not only the first successful response.
ContractResources, events, errors and versions.
ReliabilityIdempotency, queues and retries.
OperationsTraceability, metrics and support.
An integration must work when something fails
The hard part starts with unstable networks, partial data, supplier changes and duplicated operations.
- An external failure leaves inconsistent data.
- Duplicate webhooks trigger repeated operations.
- A transaction cannot be reconstructed end to end.
- Consumers depend on application internals.
- An API must evolve without breaking existing clients.
What the work leaves in place
Final scope is agreed against available evidence and the risk to reduce.
Success, partial failure, retry, cancellation and compensation.
Authentication, authorization, signing, limits and secrets.
Endpoints, clients, webhooks, queues and persistence.
Cases, doubles, sandboxes and compatibility validation.
Correlation IDs, logs, metrics, alerts and runbooks.

What must be decided with context
We make conditions and limits explicit to avoid universal recommendations.
Latency, coupling, consistency and failure tolerance decide.
We define what must be immediate and what may converge.
Compatibility is designed before several consumers exist.
Questions before starting
Answers about scope, evidence and ways of working.
Do you integrate third-party APIs?
Yes, assessing limits, authentication, sandbox, availability and change strategy.
How do you prevent duplicates?
Through idempotency keys, persisted state and explicit retry handling.
Do you document the API?
Yes, including contract, examples, errors, authentication and operational criteria.
Can you integrate a legacy system?
Yes. A stable boundary often isolates the existing system’s peculiarities.
