From 30th November, Microsoft is rolling out changes to Power Automate that could quietly break key workflows across your organisation — particularly those using HTTP and Teams webhook triggers. If your organisation relies on Power Automate for process automation, this isn’t just an IT issue — it’s a potential operational risk that could impact productivity across multiple departments.
If your team uses Power Automate to handle approvals, notifications, or cross-system integration via HTTP or Teams triggers, you need to act now.
What's changing?
Microsoft is tightening the way HTTP and Teams webhook triggers work in Power Automate. While these updates improve security and performance, they will also invalidate certain existing flows unless they are manually updated. This means:
- HTTP and Teams webhook flows built using older or unsupported configurations may stop working without warning.
- Impacted flows will fail silently, leaving teams unaware until business operations are disrupted.
If you have dozens — or hundreds — of flows running across departments, the risk compounds fast.
Why these matters?
For organisations, Power Automate is often woven into the daily rhythm of work — streamlining onboarding, managing approvals, triggering alerts, and integrating systems across business units.
When these flows break:
- Approvals can go missing
- Critical alerts from Teams or external systems may never reach your staff
- Inter-department workflows stall
- Employees are forced back to manual workarounds
- Business units lose trust in your automation investments
Even a single broken flow in HR, Finance, or Operations can create cascading delays and inefficiencies. Now multiply that by every team depending on these automations.
With the 30th November deadline fast approaching, it’s not about if you’ll be affected — it’s about how much disruption you’re willing to risk.
Don’t wait for things to break
The technical fix may be straightforward — but identifying every vulnerable flow across a large-scale environment isn’t.
