Context
We record the current state, objective, constraints, access and the definition of done.
Scope
I separate the required release from optional work and identify dependencies before changes begin.
Implementation
Work happens locally or on staging, with a practical way to compare and roll back risky changes.
When is this service useful?
An API integration is needed when one system must securely create, read or update data in another without manual transfer.
- A form or checkout must create a contact, deal or order in an external system.
- The website reads prices, stock, delivery status or other data from an API.
- An external service sends a webhook that must update application state.
What is included?
Contract review
I check documentation, authentication, rate limits, environments and required fields.
Data mapping
I define identifier, type, date and status mappings between systems.
Implementation
Secrets stay on the backend, payloads are validated and expected responses are handled.
Observability
I add logs without exposed secrets, actionable errors and controlled retry behaviour.
How the work proceeds
- Context. We record the current state, objective, constraints, access and the definition of done.
- Scope. I separate the required release from optional work and identify dependencies before changes begin.
- Implementation. Work happens locally or on staging, with a practical way to compare and roll back risky changes.
- Verification. I test priority pages, mobile widths, links and the complete user journey that the work affects.
What is controlled before release?
- An undocumented or unstable API can change the scope after the proof of concept.
- Webhook authenticity is verified using the method supported by the provider.
- Personal and payment data is transferred only where necessary.

Frequently asked questions
What is needed to estimate an integration?
API documentation, a description of the workflow, sample fields and sandbox access where available.
Can a service be integrated without an API?
Sometimes an official connector or import exists. Fragile workarounds should not run a critical process.
Do you support webhooks?
Yes, including signature checks, duplicate events, idempotency and logging.
Need to connect two systems?
Send the API documentation and a short workflow: where data starts and what should happen next.
