Description
I'm trying to enable Microsoft Teams notifications from Spring Boot Admin. I've added the following to my application.properties:
spring.boot.admin.notify.ms-teams.enabled=true
spring.boot.admin.notify.ms-teams.webhook-url=<myWebhookUrl>
I can see the MicrosoftTeamsNotifier trying to send but the following errors are logged:
2026-04-29T22:57:51.912+0000 [https-jsse-nio-9743-exec-2] ERROR [MicrosoftTeamsNotifier] - Couldn't notify for event InstanceRegisteredEvent(super=InstanceEvent(instance=9492d28f9ad0, version=0, timestamp=2026-04-29T22:57:50.174145Z, type=REGISTERED), registration=Registration(name=My App, managementUrl=https://localhost:9743/actuator, healthUrl=https://localhost:9743/actuator/health, serviceUrl=https://localhost:9743/, source=http-api))

I've followed the documentation here to set up a Webhooks on my Teams channel: https://support.microsoft.com/en-us/office/create-incoming-webhooks-with-workflows-for-microsoft-teams-8ae491c7-0394-4861-ba59-055e33f75498
As far as I can tell there is no authentication required for the Webhooks I set up in Teams. The description when I create one says:
Generate a webhook URL that lets anyone send external systems updates into a channel using rich adaptive cards or message cards.
I've dug through all the settings I can find and I don't see anything about authentication or permissions. I could be wrong and my organization has some global security setting turned on that I can't see. I did see some posts on Stack Overflow saying that authentication errors can appear when there are bad requests and that this makes debugging very difficult.
However, while digging around I found that Microsoft seems to have changed the API for Webhooks, see this announcement: https://devblogs.microsoft.com/microsoft365dev/retirement-of-office-365-connectors-within-microsoft-teams/
And it looks like the updated "Workflows" mechanism expects Adaptive Card JSON objects as inputs: https://adaptivecards.microsoft.com/?topic=AdaptiveCard
I'm definitely not an expert on any of this, but the examples of Adaptive Card structures do not appear to match the simple Message, Section, and Fact POJOs in Spring Boot Admin's MicrosoftTeamsNotifier. It looks like these classes have not been significantly changed since 2018, so I suspect they do not function with modern Teams.
