Prometheus Alertmanager notifications in Microsoft Teams

Prometheus Alertmanager alerts in Teams — firing and resolved, no template config. Per My Last Webhook normalizes Alertmanager events into rich Adaptive Cards and posts them to a Teams channel, a person's DM, or a webhook — the successor to Office 365 Connectors.

How it works

Alertmanager POSTs a webhook to your private ingest URL when a build runs.
We normalize it — the same card format as every other platform.
The card lands in your chosen Teams destination, with routing and noise controls applied.

Set up in minutes

Create a subscription in the app (platform: Alertmanager), copy its ingest URL, then:

Create a subscription (platform Alertmanager) and copy its ingest URL.

In your Alertmanager config, add a receiver with a webhook_configs entry.

Set url to your ingest URL — the fixed payload is normalized as-is (no template).

Route the alerts you want to that receiver.
