API development & integration

Your systems should speak to each other.

When a business runs on a website, an app, a CRM, an ERP, payment providers and supplier feeds, they all need to agree. That's where we're most useful.

Scenario

    01Why integration matters

    We don't just build interfaces. We connect businesses.

    The hard part isn't any one system — it's keeping all of them in agreement, and planning for the APIs you don't control.

    What the integration layer handles

    Makes sure every request is allowedAuthentication
    OAuth, API keys, SSO and signed requests — per system and per partner.
    Runs multi-step work in the right orderOrchestration
    An order touches payments, stock and the ERP. If step three fails, steps one and two are handled properly.
    Translates between systemsData transformation
    Field mapping, currencies, units and formats — defined once, versioned and tested.
    Keeps records in agreementSynchronization
    One system owns each record. Everything else follows it, with reconciliation for the rest.
    Reacts when something changesWebhooks & events
    Signed, verified, de-duplicated and processed exactly once.
    Copes when a system misbehavesError handling
    Timeouts, retries with backoff, queues and dead-letter handling for APIs you don't control.
    Tells a person when it mattersObservability
    Structured logs, health dashboards and alerts routed to someone — not discovered by a customer.

    When things go wrong

    1. A supplier API times out

      Queued requests, per-supplier timeouts and partial results — the customer still gets an answer.

    2. A webhook arrives twice

      Idempotency keys make every write safe to retry. No duplicate orders, no double charges.

    3. Two systems disagree

      One system of record per entity, agreed up front, with reconciliation reports for the rest.

    4. An integration silently stops

      Health dashboards, dead-letter queues and alerts routed to a person.

    02Is this you?

    You might need this if…

    1. Staff copy data between systems by hand
    2. Integrations break silently and nobody notices for days
    3. A partner or supplier API is slow, inconsistent or poorly documented
    4. You need to expose your own API to customers or partners

    Delivery

    1. 01

      Map the data

      Which system owns which record — and what happens when they disagree.

    2. 02

      Design for unreliability

      Queues, retries, idempotency and timeouts for APIs you don't control.

    3. 03

      Make it observable

      Logs, alerts and dashboards so failures are found before customers notice.
