MFA for humans, keys for machines: the automation problem in ManageEngine tooling

A sysadmin posted a long PowerShell script to r/ManageEngine with a simple goal behind it: authenticate to Endpoint Central's API and pull the list of machines with agents installed, so he could cross-check against Active Directory and find laptops missing coverage. A routine, sensible automation.

The script exists because, as he describes it, turning on MFA left no supported path to a long-lived token. No way to exempt a single local service account from MFA. No API-key flow that sidesteps the interactive login. So he was left scripting the human login dance, OTP step included, with AI assistance, and it still did not work.

The most telling reply came from a customer of ten years: he had the integration working, then a server upgrade broke it, as it apparently does every time. "Every time the server upgrades, I go through this. Its incredibly annoying, and only the sr developers know anything about it." His use case was equally modest: pulling licensing info.

One more data point from the same community: the ServiceDesk Plus REST API documentation marks its Workstation endpoint as deprecated, and a customer's question about what replaces it sat unanswered. Deprecation without a documented successor is its own kind of broken.

Security settings should not be a choice against automation

The pattern here is a design gap, not a bug: the product treats authentication as something humans do. Turn on the security control every auditor now requires, and the machines that depend on the API lose their path in.

Mature API design solved this long ago, and the shape of the solution is well known. Humans authenticate interactively with MFA. Machines authenticate with their own first-class identities: scoped API keys or service accounts with credentials that do not expire mid-quarter, cannot be phished through an OTP flow, and are exempt from interactive controls precisely because they carry narrower permissions. The two paths coexist; enabling one never degrades the other.

When a platform lacks that separation, customers get pushed into exactly the workarounds visible in these threads, and every one of them is worse than the feature would have been: scripts that impersonate humans through login flows, MFA left off "just for the API user," credentials embedded in automation with broader rights than the task needs, or integration work abandoned entirely, leaving gaps like unmonitored agent coverage.

Integrations are production infrastructure

The second half of the ten-year customer's complaint deserves its own paragraph: the upgrade tax. An integration that breaks on every server upgrade is not an integration; it is a recurring project. The cost lands invisibly, in the hours a senior admin spends re-solving a solved problem, and in the automations that quietly never get rebuilt after the third breakage.

The discipline that prevents it is unglamorous: versioned APIs, deprecation with documented replacements and overlap periods, and changelogs that name breaking changes before customers find them in stack traces. If a vendor's community threads show customers rediscovering their auth flow after every upgrade, the API is telling you how it will treat your automation.

Three questions for any vendor's API

Before you build on a management platform's API, get written answers to three questions.

How does a non-human client authenticate when MFA is enforced tenant-wide? The answer should name a machine-identity mechanism, not describe a workaround.

What is the deprecation policy? Version support windows, documented replacement endpoints, and advance notice, with examples from the last year.

And what broke in the last three upgrades? Every platform has an answer; the honest ones can show you where it was communicated.

A platform that fails these questions can still be a fine product for clicking around in. It cannot be the foundation of an automated operation, and automation is where every serious IT team is headed.

Where Sensaka fits

Sensaka treats integrations as production infrastructure, because in our customers' environments they are: asset data flowing to CMDBs, alerts flowing to ticketing, inventory feeding compliance reports. Machine access is designed as machine access, and we will happily answer the three questions above in writing, including the uncomfortable third one.

If your current platform's API costs you a re-integration project every upgrade cycle, bring us the use case that keeps breaking. That is a good first demo.
