APIs & Integrations

REST, GraphQL, and event-driven integrations that connect your systems to each other and to the third parties you depend on.

What we do

APIs & integrations — where systems actually meet

Integration work is where projects often go quiet and bills go up. We have built enough of them to know which shortcuts cost you later and which abstractions pay for themselves.

What we do

  • Public APIs — spec-first (OpenAPI or GraphQL SDL), versioned, authenticated properly, rate-limited, observable. Documentation is a deliverable, not an afterthought.
  • Private / internal APIs — for your mobile app, your web app, your partner channel.
  • Third-party integrations — payments, auth, email, CRM, shipping, tax, identity, messaging, commerce.
  • Webhooks — subscribers that are idempotent, retry sensibly, and do not lose events when the downstream is down.
  • Event-driven architectures — queues and streams where the workload actually benefits. Not as a status symbol.

How we build things that keep working

  • Contract first — OpenAPI or SDL reviewed before code is written.
  • Auth, auth, auth — the most common production failure mode. OAuth2, JWT with rotation, API keys with clear scoping. No shortcuts.
  • Rate limiting and idempotency — every write endpoint idempotent; every consumer rate-limited.
  • Observability — request IDs, structured logs, dashboards, alerts. You should know something is wrong before a customer tells you.
  • Tests — contract tests, integration tests against real third-party sandboxes, synthetic probes in production.

Typical timeline

Three indicative engagement sizes

Small

2–4 weeks — one integration or a small API

Medium

4–10 weeks — public API or multi-service integration

Large

10+ weeks — event-driven or migration of many legacy integrations

FAQ

Common questions about apis & integrations

Which third parties have you worked with? +

Stripe, PayPal, Shopify, QuickBooks, Salesforce, HubSpot, Slack, Twilio, Intercom, Mailgun, Cloudflare, AWS SES / S3, Google Workspace — plus dozens of smaller ones. Odoo's XML-RPC and JSON-RPC is a given.

REST or GraphQL? +

Depends on the clients. REST is fine for most backends. GraphQL pays off when clients are mobile or frontend-heavy and benefit from tailored queries. We will recommend based on your actual use case.

Event-driven architectures? +

Yes — queues (RabbitMQ, Redis, SQS), streams (Kafka), serverless event buses (EventBridge). We use these when the problem warrants it, not because they are on the roadmap.
