The goal of this integration is to improve collaboration by triggering notifications directly in Teams whenever specific actions take place in ServiceNow (for example, when an incident/Change/Problem is created or updated).
We can achieve this – it is possible to send approval or rejection updates for a specific change directly to a Microsoft Teams channel.
I have implemented a similar integration in my project.
For Microsoft Teams Integration in ServiceNow:
Create a Teams channel.
Add the "Incoming Webhook" app to the channel.
Copy the Webhook URL – this is important.
Ensure the Microsoft Teams Spoke is installed in your ServiceNow instance.
Create a Flow using the Flow Designer.
Add a Trigger as per your requirement.
Include the relevant Microsoft Teams action (in this case, we use "Post Change Details").
You can refer to this YouTube video for a detailed walkthrough on integrating Microsoft Teams with ServiceNow: https://www.youtube.com/watch?v=lKvPCYPjcA0
The most important part of this setup is the Flow, which should be designed according to your business requirements — i.e., when you want to trigger the message and what content should be posted.
I've also attached a screenshot showing what I tried on my PDI for your reference.
This is how the basic flow will look.
