3rd Party & API Integration Services for Australian Businesses
Afterpay, Auspost, Stripe, Klaviyo, HubSpot, Twilio — these services have APIs. ChainZ connects them to Australian businesses' products and platforms cleanly, so the integration is invisible to your users and maintenance-free for your team.
3rd Party & API Integration:
Six things we deliver.
A review of the third-party API before we commit to a design — what it can and can't do, what limitations apply (rate limits, sandbox restrictions, approval requirements), and whether the API actually supports your use case as described.
The integration built as a dedicated module — not scattered through your codebase. When the third-party API changes (and it will), only one place needs updating. Versioned, testable, and maintainable.
Most third-party APIs push data to your system via webhooks. We handle the full webhook lifecycle: signature verification, idempotency, retry logic, and event queuing — the parts most DIY integrations get wrong.
OAuth flows, API key rotation, token refresh cycles, and secure credential storage — handled correctly from day one. No API keys hardcoded in environment files, no tokens expiring and silently breaking the integration.
Thorough testing in the third-party's sandbox environment before production — including error paths, edge cases, and rate limit behaviour. We test what happens when the API returns an error, not just when it succeeds.
Integration documentation covering authentication, endpoint usage, error codes, and the webhook event model — so your team or another developer can maintain or extend the integration without reverse-engineering it.

Multi-platform social analytics integration across Instagram, Facebook, and LINE
A marketing agency needed unified analytics across three social platforms — Instagram, Facebook, and LINE — for 30+ client accounts simultaneously. ChainZ built a unified API integration layer handling authentication across all three providers, normalising data formats, managing rate limits per platform, and feeding a single analytics dashboard. Manual reporting eliminated entirely.
ChainZ built ChainHub — a multi-agent orchestration platform connecting 500+ AI models through a single API. ChainHub uses the same agent architecture we deploy for clients: routing logic, tool calling, context management, and fallback handling running reliably at scale, every day.
