Summary

Slack is a cloud-based collaboration tool used to communicate teams. JEMHCloud supports Slack notifications from Issue Events and Post Functions. You will be able to notify your Slack Channels when JEMHC detects an issue change.

Configuring the Slack Connection

In order to send Slack notifications from Issue and Post function events, you need to set up a Slack connection first. The connection knows how to send Slack messages via Slack Rest APIs.

To create a Slack Connection:

Log into your Slack's Team
Go to JEMH Cloud → Slack Connection → Connect To Slack
Authorize JEMHC to be installed to Slack as an App. This allows communication from JEMHCloud to Slack
Check out new Slack Connection on the screen.

Once you have the connection created, you can set Slack Notification Mappings to drive Slack notifications from Issue Created/Updated/Deleted events or Slack Post Functions to drive Slack notifications from transition events.

Send Slack notifications from issue events

Like Email and SMS Notification Mapping, Slack Notification Mapping is in charge of sending Slack messages from Issue events through the Slack Connection.

Creating a Slack Notification Mapping:

Go to JEMH Cloud → Notifications → Slack → Create
Complete the form, select the nominated projects, select the Slack Connection you want to use and the channel that will receive Slack messages. Enter a velocity script if you wat to modify the notification behavior at runtime (more below).
On Submit, you should see the new Slack mapping
To test the mapping, create an issue in the nominated project and go to Auditing → Events
You should see the issue created event in the queue. When event has been processed, the configured channel in the mapping should have received an Slack message.
The report of the event should confirm the message sent
In Auditing → Outbound Messages → Type Slack, the table should show the Slack messages sent and the cog icon should show their contents.

Send Slack Notifications from Post Functions

JEMHCloud allows you to send Slack notifications when Issue transitions are performed through JIRA Post Functions.

Adding the Slack Notification Post Function to workflow transition:

Go to right corner Cog → JIRA Administration → Issue → Workflows. Edit the workflow of the project you want to add the Post Function
Click on the transition you want to change and select the Post Functions tab. Click on Add post function
Select Send Slack Notification by JEMHCloud and click Add
Set the Slack Connection, Chanel and Velocity script if necessary. Press Add/Update
Move the Post Function to last position and publish the workflow draft.
Remember to publish the workflow change draft!
To test the post function, go to an issue and perform the transition.
Post function event should appear in JEMH Cloud → Notifications → Events.
The event report:
The message in Slack:
In Auditing → Outbound Messages, the table should show the SLACK messages sent and the cog icon should show their contents.

Filter Scripts

Both Slack Notification Mapping and Slack Post Function behavior can be changed at runtime with a Velocity Script. The script can use the event data or be time-based to change how notifications are performed.

Change Channel

Change channel when Critical

#if ($context.issue.fields.priority.name.textValue() != 'Critical')
  $slackNotificationUtils.setChannel('AnotherChannelNameOrId') ## JEMHC looks for the channel by either name or id
#end

Restrict notifications to specific time ranges

Notify only after hours

#if (!$dateTimeUtils.betweenHours("18:00", "06:00"))
   $slackNotificationUtils.inhibitNotification() ## Slack messages are not sent during business hours **
#end

Restrict by priority

#if ($context.issue.fields.priority.name.textValue() != 'Blocker')
   $slackNotificationUtils.inhibitNotification()
#end

Velocity Script cannot be validated at configuration time (for example the dynamic channel). You should test the script by re-executing events in Auditing → Events
