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.).
