Acknowledge course updates with one reaction
Use a consistent Slack reaction to mark a course update that meets a rule you define.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Important course updates can be hard to spot in busy Slack conversations and may lack a clear acknowledgment.
- Mark a matching Slack message with a consistent reaction.
- Use the course details supplied to the webhook to decide whether to react.
- Make acknowledgment visible in the conversation.
Setup
Build it in a few focused steps.
- 1Connect Blackboard and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis which supplied Blackboard update should lead to a reaction and which Slack message and emoji to use.
- 4Choose a webhook trigger and select where run reports should go.
- 5Test with one real update and its Slack message.
Questions about this workflow
Can this create a Blackboard announcement?
No. The action adds a reaction to an existing Slack message. It does not create or edit Blackboard content.
What details must be supplied?
Provide enough Blackboard update context to evaluate your rule, plus the Slack channel and message timestamp needed to identify the message.
