We tried to automate a simple HR workflow last year. Pull employee data from our HR system, match it against records in another platform, update the relevant fields, done. The kind of thing that should take an afternoon to set up and then run itself.

It didn't work. Our HR platform, iSolved, offers a limited, read-only API. To access even basic data programmatically, we had to go through a third-party vendor and pay for the privilege. What we got back still wasn't flexible enough for our specific workflows. No ability to write data back. No way to tailor the integration to our needs. So we built a workaround: manual export, automated matching script, output to a spreadsheet that HR uses to batch-enter updates instead of going case by case. It's better than fully manual. But it's duct tape on a problem that shouldn't exist.

This isn't a story about one vendor. It's a story about what happens when a system wasn't built to connect to other systems. And it's playing out in organizations of every size, across every sector.

Why This Matters More Now Than It Did Two Years Ago

Integration debt has always been expensive. In 2026, it's become something worse: a blocker for automation and AI.

Consider the progression. You want to automate a workflow that spans two systems. To automate it, you need data from both systems in a structured, reliable format. If one system won't expose its data through a capable API, the automation stalls before it starts. You're back to manual exports and spreadsheets.

Now scale that to AI. AI tools need connected, clean, accessible data to do anything useful. If your employee data lives in a system with a read-only API that requires a paid third-party intermediary, you're not building AI-powered HR workflows. You're not even building basic automations. You're paying someone to copy data between systems, which is the exact opposite of where organizations need to be heading.

Contrast that with a platform built API-first. We use Atlassian's ecosystem across Tactis, and the difference is night and day. Jira and Confluence expose comprehensive REST APIs with full read and write access across well-documented endpoints. We use those APIs to update documentation across the platform as policies and processes change, pull project and client data for executive reporting without manual assembly, and maintain a single, reliable source of truth across teams. The automation possibilities compound because the platform was designed to let other systems in. Nearly every operation you can perform in the browser, you can also perform through the API.

That's the real divide in 2026. It's not between organizations with new systems and organizations with old ones. It's between organizations whose systems can talk to each other and organizations whose systems can't. The first group is automating workflows and experimenting with AI. The second is still exporting CSVs.

What to Do When You're Stuck with a Bad API

Not every system can be replaced on your timeline. You might be mid-contract, or the switching costs are prohibitive, or the system does its core job well enough that a full replacement isn't justified. The API is the problem, not the product.

This is where middleware and integration platforms earn their keep. Tools like MuleSoft, Workato, or even lighter-weight options like Make can sit between a limited system and the rest of your stack, normalizing data formats and bridging gaps that the native API can't cover. You're essentially building a wrapper: a modern API layer around a system that doesn't have one.

Sound familiar? It should. It's the same principle as strangler fig modernization, applied at the integration layer instead of the application layer. You don't wait for the vendor to fix their API. You build around the limitation and reduce your dependency on it.

Where to Start

If your systems don't talk to each other and the workarounds are piling up, the starting point is simpler than most modernization pitches make it sound.

Map your data flows first. Understand how data actually moves through your organization today. Where are the manual handoffs? Where does data get duplicated or fall out of sync? Where is a system's API limitation blocking an automation you've already identified? That map becomes the blueprint for your API strategy and your automation roadmap simultaneously.

From there, pick the highest-value integration point. Start where the disconnection causes the most pain, or where the automation opportunity is clearest. Build a secure, documented API for that connection. Get it working, prove the value, and use that success to fund the next phase.

That's how modernization programs build momentum. Not with a five-year roadmap and a prayer, but with working integrations that make someone's job measurably better this quarter, and set the foundation for the automation and AI work that's already overdue.

At Tactis, we build integrations between complex system environments for federal agencies and mission-driven organizations, and we're increasingly focused on making sure those integrations support automation and AI readiness from the start. If your systems need to talk to each other better, or if you're staring at a modernization effort and want to avoid the big-bang risk, we'd welcome the conversation.
