    Most Aussie businesses run on a stack of 8–15 SaaS tools that don't talk to each other — Xero for accounts, HubSpot for sales, Shopify for commerce, a job-management tool for ops, plus three internal spreadsheets holding it all together. Custom API integrations close those gaps so data flows automatically between systems and your team stops copy-pasting between tabs.

    We design and build both sides of the wire: custom APIs on top of your existing data (REST or GraphQL, authenticated, rate-limited, documented) so other systems can read and write to your platform safely; and third-party integrations with the SaaS tools you already use — sync, webhooks, OAuth, background jobs and error handling done right.

    Pairs naturally with our web app builds and internal tools when you need the integration plus the dashboard to use it.

    Why Custom Integration Beats Zapier at Scale

    Reliable, monitored, version-controlled — instead of a tangle of no-code flows.

    Reliable — proper error handling, retries and alerting, not 'Zap stopped working'

    Affordable at scale — no per-task pricing that explodes past 10k tasks/month

    Custom logic — transform, enrich and validate data your way

    Auditable — every API call logged, every payload stored, every error visible

    Secure — OAuth, signed webhooks, secret rotation, no shared API keys lying around

    Yours forever — code in your GitHub, no vendor lock-in

    What an API Integration Project Includes

    The standard pieces every production integration needs.

    Custom REST / GraphQL APIs

    Versioned, documented (OpenAPI / GraphQL schema), authenticated (JWT, API keys, OAuth2), rate-limited and cached. Designed so partners or your own apps can integrate against it without confusion.

    Third-Party Sync

    Two-way sync with Xero, MYOB, HubSpot, Salesforce, Pipedrive, Stripe, Shopify, ServiceM8, Microsoft 365, Google Workspace and any tool with a public API. Webhooks where supported, polling fallback when not.

    Auth, Secrets & Compliance

    OAuth2 flows for end-user authorisation, signed webhooks to verify payload authenticity, encrypted secret storage, scoped API keys, and full audit logs of every external request. Built to handle PII responsibly.

    Monitoring & Retries

    Background job queues with exponential backoff, dead-letter handling, real-time error alerting to email / Slack, and dashboards showing sync health, throughput and latency. You find out about a broken sync before your customers do.

    Why Aussie Businesses Trust Us With Their Integrations

    Integrations are where most projects quietly fail — happy path works in the demo, then 3 months later sync silently stops, payloads change, OAuth tokens expire, edge cases break. We've been building production integrations for 10+ years and treat them as first-class software: monitored, versioned, tested, observable.

    Same senior engineer scopes the integration, writes the code, and stays involved post-launch. Modern stack (TypeScript, Supabase Edge Functions, queued jobs), fixed-price quoting, and full ownership of the code and credentials.

    Frequently Asked Questions

    How much does API development & integration cost in Australia?

    Most integration projects land between $3,000 and $20,000 depending on scope — a single Xero or HubSpot sync is on the lower end, a multi-system data hub with custom APIs is on the higher end. Always fixed-price after a free scoping call.

    Why not just use Zapier or Make?

    Great for quick wins and low-volume flows. They get expensive past ~10k tasks/month, hard to debug when they fail, and impossible to handle properly when the payload is complex (multi-step transforms, conditional logic, large datasets, retries). Most clients come to us after Zapier hits 4 figures a month and still misses a sync once a week.

    Can you build us a public API for our own product?

    Yes — we design and ship versioned REST or GraphQL APIs with proper auth (JWT / OAuth2 / API keys), rate-limiting, OpenAPI documentation, sandbox environments and partner onboarding flows. Built to be safe to publish, not just functional internally.

    How do you handle authentication with third parties?

    OAuth2 wherever the third-party supports it (Xero, HubSpot, Microsoft 365, Google Workspace), API keys stored encrypted in Supabase secrets vault otherwise, and signed webhook verification on every inbound payload. No tokens in source control, no shared admin credentials.

    What happens when an integration breaks?

    Every sync runs as a queued background job with retries, exponential backoff and a dead-letter queue. Failures hit an alerting channel (email / Slack) inside minutes, and you (or we, if on retainer) can replay failed jobs from the admin dashboard. Most integrations self-heal without you noticing.

    Do I own the code?

    Yes. Code lives in your GitHub, infrastructure runs on your accounts (Supabase, hosting), integration credentials in your vault. You can move providers or teams at any point.
