Make a Cats image discoverable in Slack
Send Notis an image request and context, then have it add the Cats image URL to Slack as a remote file.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
Why this helps
An image URL in an isolated request is harder for teammates to discover and share later.
- Makes the image reference discoverable in Slack.
- Gives the team a shareable Slack entry for the Cats image.
- Uses the request context to explain why the image is relevant.
Setup
Build it in a few focused steps.
- 1Connect Cats and Slack once in the Notis portal.
- 2Create an automation and describe the image lookup and remote-file outcome in one instruction.
- 3Pick a webhook as the trigger.
- 4Choose where Notis should send run reports.
- 5Test with one real image request and an accessible image URL.
