APIs and integrations that don't break at 2am

We design clean public and internal APIs, and we connect the systems you already rely on so that data flows once, correctly, without anyone re-typing it.

API Development & Integrations

What you receive

  • System and data-flow map
  • OpenAPI or GraphQL contracts
  • Production APIs and connectors
  • Automated contract tests
  • Developer documentation
  • Monitoring and reconciliation jobs

Our approach to APIs & Integrations

Integrations rarely fail on the happy path. They fail on rate limits, duplicated webhooks, partial outages and a vendor quietly changing a field. Our integrations are built for that reality, with idempotency, retries, reconciliation and alerts from the start.

If you are publishing an API, we treat it as a product: a contract written first in OpenAPI, consistent errors, sensible versioning and documentation developers can follow without emailing you.

This is likely a fit if…

  • Staff copy data between your CRM, finance and operations systems
  • Existing integrations fail silently and data drifts out of sync
  • Partners or customers are asking for API access
  • You are stuck on a vendor because everything is wired directly into it
Capabilities

What’s included

API design and build

REST, GraphQL and gRPC services with contract-first design and consistent conventions.

Third-party integrations

Salesforce, HubSpot, Stripe, Twilio, NetSuite, SAP, Shopify and most systems with an API.

Webhooks and events

Reliable delivery with signing, replay, retries and deduplication at both ends.

Middleware and iPaaS

An integration layer that keeps vendors swappable, custom-built or on platforms like Workato.

API security

OAuth 2.0 and OIDC, scoped keys, rate limiting and OWASP API Top 10 controls.

Developer experience

Interactive documentation, SDKs, sandboxes and change logs for the people using your API.

The engagement

How we deliver it

  1. 01

    System inventory

    We map every system, owner, data flow and failure mode involved.

  2. 02

    Contract design

    API contracts and data mappings are agreed in writing before implementation.

  3. 03

    Build and test

    Contract tests, sandbox runs and fault injection prove behaviour under failure.

  4. 04

    Monitor and evolve

    Reconciliation jobs and alerts catch drift early, with a versioning plan for change.

FAQ

APIs & Integrations questions

The things founders and leadership teams actually ask us, with honest answers. Anything else, we’re one message away.

Ask your own question
  • Usually. We can work through database views, file exchange or a thin adapter service, and we will flag any approach that creates long-term risk.
