Slack notifications

Oppex posts incident updates to the Slack channels connected to a service, so your team can follow an incident without opening Oppex. Slack notifications go to channels, not to individual responders, and they do not replace the contact methods on the escalation policy.

Permissions

A service administrator connects channels and chooses events in the service's settings. Your organization must connect a Slack workspace first.

What a post looks like​

When an incident is assigned, Oppex posts the title, service, severity, assignee, and time. Later updates for the same incident go into the same thread.

View Incident

The View Incident button opens the incident in Oppex. You cannot acknowledge or resolve an incident from Slack.

Events Oppex can post​

A service administrator ticks the events to post under Notification Events: Triggered, Assigned, Acknowledged, Service Change, Severity Change, and Resolved. Each post names who acted, for example "Acknowledged by" or "Resolved by".

Connect a channel to a service​

  1. In the service's settings, click Add Slack Channel.
  2. In Search channels..., find and select the channel.
  3. Under Notification Events, select the events to post.
  4. Save the service.
