It happens in almost every HubSpot portal audit: buried in Settings is a connected app nobody recognizes. Installed eight months ago by someone at an agency the company no longer works with. Is it moving data? Is it reading your contacts? Can you just uninstall it, or will something break?
The instinct to delete first and ask questions later is understandable, and wrong. A connected app might be the quiet engine behind a form, a workflow, or a sync that half your pipeline depends on. Or it might be a dead trial from a tool evaluation, holding live access to your CRM for no reason. Telling the difference takes an hour of structured checking, not guesswork.
This guide is that hour, written down: where to find every connected app, how to work out what an unknown one does, how to remove it safely, and how to keep the list clean going forward.
To audit connected apps in HubSpot, open Settings, then Integrations, then Connected Apps, and review every entry: what it is, who installed it, when it was installed and last active, and what it connects. For any app you cannot identify, trace the installer, check which workflows, forms, and data flows depend on it, and confirm whether a native feature or newer tool has replaced it before you uninstall. After removal, monitor for breakage for at least two weeks. Vantage Point runs this audit as part of portal cleanup and integration architecture work.
Nobody installs a mystery app on purpose. The usual origins are all benign: an agency connected its favorite middleware during an onboarding two contracts ago; an employee evaluated a tool on a trial and connected it to real data; a predecessor wired up a quick fix for a missing feature and documented nothing; a vendor's setup wizard asked for CRM access and someone clicked approve to keep the demo moving.
Each connection is a standing credential into your customer data. Most sit idle. Some quietly run processes the business now depends on. A few keep syncing data to a vendor nobody pays anymore. You cannot tell which is which from the app name alone, which is the whole case for an audit.
Start in Settings, under Integrations, on the Connected Apps page. The Connections home view lists installed apps, and each app's details show who connected it and when. Check three adjacent places so nothing hides:
Export or screenshot the full list with installers and dates. That inventory is the audit's working document.
For each app you do not recognize, work through five questions in order:
| Finding | Decision | Action |
|---|---|---|
| Active, depended on, owner identified | Keep | Document purpose, owner, and review date |
| Active, depended on, but redundant with native features | Replace | Rebuild the process natively, migrate, then remove the app |
| Inactive, no dependencies found | Remove | Uninstall, note the date, monitor |
| Purpose unclear, low activity | Quarantine | Time-box the investigation; remove if unresolved |
| Active, no owner, vendor relationship ended | Replace or remove | Find what it feeds, rebuild or retire the flow |
The replace row deserves emphasis: the cleanest portals are the ones where recurring data movement runs on native automation or well-governed middleware, not on a patchwork of single-purpose apps. If the audit finds three tools moving the same contact data, that is a consolidation project, and our integration and data migration team can scope it properly.
Removal is easy; confidence is the work. Follow this order:
Three habits prevent a repeat. First, use HubSpot's app access controls: requiring admin approval before apps connect turns drive-by installs into deliberate decisions. Second, keep a living inventory — app, purpose, owner, install date, review date — even if it is a simple spreadsheet. Third, put the audit on a calendar: a quarterly fifteen-minute review of the connected apps list catches drift while it is still small. Teams running broader governance usually fold this into their managed services cadence so it happens whether or not anyone remembers.
Vantage Point is a HubSpot Solutions Partner, and connected-app cleanup is a standard chapter of our portal audits. Senior consultants only — no junior handoffs; the experts you meet are the experts who deliver. We inventory every integration, trace dependencies, retire what is dead, and rebuild what is needed on native tools or governed middleware through our HubSpot consulting practice. You get a portal where every connection has a name, an owner, and a reason to exist.
Every unrecognized connection is either a dependency or a risk, and guessing wrong is expensive. Vantage Point can run the audit and leave you with a clean, documented integration estate. Talk to Vantage Point about a portal audit.
Go to Settings, then Integrations, then Connected Apps. The Connections home view lists installed apps with who connected them and when. Also check the private apps section in the same area, since custom token-based integrations live there and are easy to overlook.
Not without checking first. Identify the installer, look for recent activity, review its permissions, and search workflows and forms for dependencies. An app you do not recognize may still drive a live process, so trace before you remove and monitor afterward.
Look for records it creates or updates, entries in workflow or integration logs that reference it, and any processes that started around its install date. If the installer is reachable, asking them directly is often the fastest answer.
Connected apps are typically third-party products installed from the HubSpot Marketplace or authorized via OAuth. Private apps are custom integrations built for your portal that authenticate with a private app token. Both appear under Integrations settings, and both belong in the audit.
Not always. Disconnecting in the vendor's product can leave the app installed in HubSpot, and uninstalling in HubSpot may leave a live connection on the vendor side. Remove it in both places and confirm each shows the disconnection.
Enable admin approval for new app connections, keep a simple inventory of every app with its owner and purpose, and review the connected apps list quarterly. Small, regular reviews are far cheaper than a forensic audit every few years.
A HubSpot Solutions Partner like Vantage Point can inventory your connected and private apps, trace their dependencies, safely remove what is unused, and consolidate redundant integrations onto native features or governed middleware.
