SERVICE · API INTEGRATION & MIDDLEWARE

Integration and middleware that make your systems behave as one.

When you run more than a few core systems, the gaps between them are where your business logic actually lives. The work is building that layer properly, not bolting on another connector.

The case for a real integration layer

Below a certain size, an integration layer is overkill: one CRM and one accounting tool at light volume needs a person and a scheduled export, and we’ll say so. Above roughly four connected systems and sustained volume, the off-the-shelf connectors start failing in ways that are expensive to unpick. That’s the point where a thin, business-owned, event-driven layer earns its place. Every event is captured once and handled by the systems that care; nothing is tightly coupled; retries are safe; every step is logged.

Compliance and government integrations

Where the work touches regulators, payments or government systems, the audit trail is part of the build: signed, timestamped records you can reconstruct on demand. We’ve built government work-order integrations, PCI-compliant payment tokenisation, and regulated import workflows where the record has to be exactly right.

In production

Infinity Fire Protection had to connect their Uptick work-order platform to Homes NSW after the government required every supplier to integrate directly with its work-order system. The hard part: the Homes NSW API was still being built and changed week to week, spanning 70+ endpoints that had to be orchestrated bidirectionally into Uptick for safety-critical fire-compliance work, where other vendors had already tried and failed. We built it on Nexus, event-driven with a full audit trail, and we’ve kept absorbing the client’s frequent changes since.

We engaged Paladine on very short notice to build the interface between our platform and our client’s, and they exceeded expectations. Our client frequently makes changes that need a rapid response, and Paladine have repeatedly accommodated them, keeping our systems accurate and stable. The result has had high praise from our client, who describe it as flexible, reliable, and performing exactly as required.

We recently engaged Nic and the Paladine team on very short notice to develop a system interface between our platform and our client’s. Despite the tight timeframes, Paladine not only delivered, they exceeded expectations. The team demonstrated exceptional commitment, attending multiple meetings across varying hours to ensure the solution was refined, tested, and delivered seamlessly.

Our client frequently implements system changes that require rapid response and adjustment. Paladine have repeatedly accommodated these shifts, actioning urgent updates, troubleshooting integration issues and alerting us promptly to errors originating from the client system. Their responsiveness has allowed us to maintain continuity, accuracy and system stability under circumstances that could otherwise introduce operational risk.

In addition to meeting complex functional requirements, Paladine have built in numerous automated processes that now handle tasks previously managed manually by our internal team. This automation has removed a significant administrative burden, eliminated repetitive data handling, and delivered substantial efficiency gains across the business.

The final result is a system that has not only exceeded our expectations, but has also received high praise from our client, who have described it as flexible, reliable, and performing exactly as required.

For Silk Laser, a long-running engagement, our Nexus middleware keeps their POS, delivery and web systems in sync. For MEAA we replaced a slow, unreliable member-data sync and built a tokenised payment gateway for PCI compliance.

API integration FAQs

  • Do we own the integration?

    Yes. Source and infrastructure sit in your accounts, and any competent Symfony team can maintain it.

  • Will you work with our existing stack?

    If it has an API or a webhook, we can integrate it. If it doesn’t, we can usually work around it with a small adapter or a scheduled task.

  • What if a vendor changes their API?

    We monitor the integrations we run and fix breakage under an optional Run With Us retainer (from $6,500 per month).
