File Comment Alert: Slack Notification for Box Collaboration

Collaboration feedback matters, but buried comments in Box mean delayed responses. Get a Slack alert every time someone comments.

Why this helps

You're juggling feedback across Box and Slack, but comments in Box often go unnoticed until days later. This breaks feedback loops and forces you to manually check both tools.

  • Never miss feedback or questions on your work
  • Feedback loop stays in Slack where your team works
  • Reduces tool-switching between Box and Slack
  • Ensures timely responses to collaborative input

Setup

Build it in a few focused steps.

  • 1Connect Box and Slack to Notis via the portal.
  • 2Create a new automation with the instruction: 'Send a Slack message whenever a new comment is added to this Box file.'
  • 3Specify the Box file to monitor for new comments.
  • 4Select the Slack channel for comment alerts.
  • 5Test by adding a comment to that Box file and verify the Slack notification.

Questions about this workflow

Does this include replies to comments?

Yes. Any new comment on the file triggers a notification, including replies to existing comment threads.

Will it notify about comment edits?

This trigger fires for new comments only. Edits to existing comments don't retrigger the notification.

Can I get notifications for multiple Box files?

Yes. You can create separate automations for each file you want to monitor, or ask Notis to monitor a folder.
