+# PagerDuty V2
+
+## Parameters
+
+The PagerDuty notification service is used to trigger PagerDuty events and requires specifying the following settings:
+
+* `serviceKeys` - a dictionary with the following structure:
+  * `service-name: $pagerduty-key-service-name` where `service-name` is the name you want to use for the service to make events for, and `$pagerduty-key-service-name` is a reference to the secret that contains the actual PagerDuty integration key (Events API v2 integration)
+
+If you want multiple Argo apps to trigger events to their respective PagerDuty services, create an integration key in each service you want to setup alerts for.
+
+To create a PagerDuty integration key, [follow these instructions](https://support.pagerduty.com/docs/services-and-integrations#create-a-generic-events-api-integration) to add an Events API v2 integration to the service of your choice.
+
+## Configuration
+
+The following snippet contains sample PagerDuty service configuration. It assumes the service you want to alert on is called `my-service`.
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: <secret-name>
+stringData:
+  pagerduty-key-my-service: <pd-integration-key>
+```
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: <config-map-name>
+data:
+  service.pagerdutyv2: |
+    serviceKeys:
+      my-service: $pagerduty-key-my-service
+```
+
+## Template
+
+[Notification templates](../templates.md) support specifying subject for PagerDuty notifications:
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: <config-map-name>
+data:
+  template.rollout-aborted: |
+    message: Rollout {{.rollout.metadata.name}} is aborted.
+    pagerdutyv2:
+      summary: "Rollout {{.rollout.metadata.name}} is aborted."
+      severity: "critical"
+      source: "{{.rollout.metadata.name}}"
+```
+
+The parameters for the PagerDuty configuration in the template generally match with the payload for the Events API v2 endpoint. All parameters are strings.
+
+* `summary` - (required) A brief text summary of the event, used to generate the summaries/titles of any associated alerts.
+* `severity` - (required) The perceived severity of the status the event is describing with respect to the affected system. Allowed values: `critical`, `warning`, `error`, `info`
+* `source` - (required) The unique location of the affected system, preferably a hostname or FQDN.
+* `component` - Component of the source machine that is responsible for the event.
+* `group` - Logical grouping of components of a service.
+* `class` - The class/type of the event.
+* `url` - The URL that should be used for the link "View in ArgoCD" in PagerDuty.
+
+The `timestamp` and `custom_details` parameters are not currently supported.
