APIs & Integrations

Connect payments, identity, devices and the business systems you already rely on.

Most businesses run on several systems that don't talk to each other. We design APIs and integrations that move data reliably between them, with the error handling that real-world services need.

What we build

  • REST APIs
  • Stripe and payment integrations
  • Authentication and single sign-on
  • Third-party service integrations
  • IoT and smart-device integrations
  • Existing business system integration

A good fit when

  • Data copied by hand between systems
  • Payments or bookings that need reconciliation
  • Hardware or devices that need to report to the cloud

How we approach it

  1. 01

    Contracts first

    Clear API contracts and data ownership before any code is written.

  2. 02

    Designed for failure

    Retries, idempotency and logging, because external services do go down.

  3. 03

    Secure by default

    Least-privilege credentials, signed webhooks and audited access.

Typical stack

  • ASP.NET Core
  • REST
  • Stripe
  • OAuth / OIDC
  • Webhooks
  • MQTT / device APIs
