New File Added Alert: Slack Notification for Box

Team members upload files to Box folders, but you miss them. Get a Slack alert every time a new file arrives.

Trigger

New File Added to Folder

Triggers when a new file is added to a folder in Box. This trigger monitors a specific Box folder and fires when new files are detected. Only files (not folders or web links) are monitored.

Action

Post message to channel

Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.

Why this helps

Files get uploaded to shared project folders without your immediate notice, causing delays in review or action.

  • Know immediately when files are uploaded
  • Reduce review turnaround time
  • Keep file submissions visible and actionable
  • Track project deliverables as they arrive

Setup

Build it in a few focused steps.

  • 1Connect Box and Slack to Notis.
  • 2Create an automation: 'Alert me in Slack whenever a new file is added to this Box folder.'
  • 3Select the folder to monitor (only new files, not subfolders).
  • 4Choose the Slack channel for notifications.
  • 5Test by uploading a file to that folder and confirming the alert appears.

Questions about this workflow

What's the difference between this and 'new item added'?

This tracks only new files. The other automation tracks files, folders, and web links together.

Does this include files in subfolders?

No. This monitors only the top level of the selected folder. Create separate automations for subfolders.

Can I filter by file type?

Yes. Ask Notis to only alert for specific file types (e.g., PDFs, spreadsheets, etc.).
