Hi PagerDuty team!

I'm trying to get custom details from Grafana alerts to display in our Slack notifications, but only seeing basic information.

Current Setup:

• Grafana → PagerDuty integration working (using Events API V2)
• PagerDuty → Slack integration connected (service: my-service-prod → channel: #team-alerts)
• Alerts are flowing through successfully

The Issue: Our Grafana alerts send rich custom details to PagerDuty (verified in PagerDuty incident view):

• severity: "critical"
• namespace: "production"
• pod: "api-service-7d9c5-xyz"
• cluster: "us-west-2-prod"
• component: "api-service"
• description: "Pod is in CrashLoopBackOff state..."
• runbook_url: "https://wiki.internal/runbooks/..."

However, in Slack we only see:

🔴 Pod CrashLoopBackOff Alert
Service: my-service-prod
Urgency: Low
UAcknowledge] rResolve]

What We Need: Display the custom_details fields in Slack notifications so our on-call engineers can see critical context without clicking through to PagerDuty.

What I've Tried:

1. Configured PagerDuty contact point in Grafana with Details fields mapped to templates like {{ .CommonLabels.namespace }}
2. Checked Slack integration settings in PagerDuty (Extensions → Slack → View)
3. The configuration UI only shows basic options (thread creation, channel selection) but no options for enabling custom details display

Questions:

1. Is there a way to enable custom details display in the current Slack integration?
2. Do we need to upgrade to a different Slack integration version or add Slack V2 app?
3. Can Event Orchestration be used to enrich Slack messages with custom_details?
4. Is there an API endpoint or webhook approach for more control over Slack message formatting?

Environment: Using standard PagerDuty Slack integration Service: my-service-prod Integration Key: Events API V2

Any guidance would be greatly appreciated! Looking to display the custom metadata our monitoring system sends to help reduce MTTR.
