Custom API development and integration work for Canadian businesses connecting tools that don't talk to each other out of the box. Whether you need a clean REST or GraphQL API for your platform, a one-off integration between two SaaS tools, or a full API gateway with auth and rate limiting — we build it cleanly, document it, and hand it over for your team to maintain. No lock-in, no vendor middleware fees.
We build custom APIs and integrations from the ground up — and we fix broken ones. Most engagements fall into one of three patterns: building a new REST or GraphQL API for your platform, integrating two tools that don't have a native connection (e.g. your CRM and your accounting system), or replacing a fragile no-code integration with a proper coded solution that doesn't break every time a vendor changes their schema. Everything is documented, versioned, and yours to maintain.
New APIs for your platform or product — designed to OpenAPI spec, built with proper error handling, paginated correctly, versioned for the long haul. Suitable for both customer-facing APIs and internal microservices.
Connecting tools that don't natively talk to each other — your custom CRM to QuickBooks, your booking system to your e-commerce platform, your phone system to your help desk. We handle authentication, rate limits, and error recovery so the integration doesn't silently fail.
Robust webhook receivers with signature verification, retry logic, dead-letter queues, and observability. Especially valuable when you're processing webhooks from Stripe, Twilio, or other high-volume sources where dropped events cost real money.
When you need to expose multiple internal services to clients or partners, we build a unified API gateway with OAuth, JWT, or API key auth, per-client rate limiting, and detailed access logs.
We walk through the systems you need to connect, the data that has to move between them, and the failure modes you can't afford. Free.
We document the API contract or integration spec, identify rate limits, auth requirements, and edge cases — then quote fixed-price against the spec.
We build the API or integration with proper test coverage, error handling, and observability. You see working code in staging before anything touches production.
We deploy, hand over code, OpenAPI docs, runbook, and deployment access. Optional monthly retainer for monitoring, version bumps, and new integration requests.
Reliable integrations that don't silently break when vendors change schemas
Starting at $3,500 and up to $40,000 depending on scope. Every project starts with a free 15-minute discovery call. We scope the work in writing, then quote it fixed-price — no surprises, no hourly drift. Client owns the code, the data, and the IP at launch.

Both. About half our API work is building new APIs for client platforms; the other half is connecting tools that already exist but don't talk natively. We're equally comfortable with greenfield work and inheriting messy existing systems.
Yes — this is one of the most common requests we get. Most no-code automations work great until volume scales or a vendor changes their API. We rewrite them as proper code (Node, Python, or n8n self-hosted) with better error handling and no per-task fees.
Yes. Every REST API ships with full OpenAPI/Swagger documentation. GraphQL APIs include schema documentation and example queries. Internal APIs get inline JSDoc and architecture notes.
Most APIs are built on Node.js (TypeScript), Python (FastAPI), or Go depending on the use case. Database choices default to Postgres unless your stack dictates otherwise. Deployed to Vercel, Cloudflare Workers, or any Canadian-hosted VPS depending on residency requirements.
Default deployment is on Canadian infrastructure — Cloudflare Canadian regions, Vercel Canadian edge, or VPS providers with Canadian data centres. For regulated industries (healthcare, legal, financial) we can deploy entirely on-premise or in your own cloud tenancy.
