Microsoft retired the legacy Teams Incoming Webhook connectors, so you can no longer just post JSON payloads directly to Teams channels.
There are a few alternatives that work well with Dynatrace alerts:
1. Use the new Microsoft Teams Incoming Webhooks (v2) via Entra ID
You can still use webhooks, but now they must be authorized through Entra ID (Azure AD) — they aren’t anonymous URLs anymore.
Dynatrace doesn’t yet support the new authentication model natively, so the common workaround is to route alerts through an Azure Function or Logic App that:
Receives the Dynatrace webhook payload
Authenticates to Microsoft Graph or the new webhook endpoint
Posts the message into Teams
Dynatrace → Azure Function / Logic App → Teams (Graph API or Connector v2)
Use Power Automate
You can create a Power Automate flow with an HTTP trigger and then use the Post adaptive card to Teams action.
Dynatrace sends the webhook to the Power Automate endpoint, and the flow formats and delivers it to Teams.
Long story short:
You still need to use a webhook, but since Microsoft retired the old anonymous connectors, you have to handle it on the Azure side — for example, through an Azure Logic App, Azure Function, or Power Automate flow that receives the Dynatrace webhook payload and then posts it to Teams via Graph API or the new Teams connector v2.
