Slack - Send Message Conditionally

Overview

Send a message to Slack conditionally by determining if a file exists or not.

Tasks built with this Template should never fail, as the presence or lack or presence of the file only indicates whether or not the message should be sent.

Works primarily when used as part of a Workflow, where a File can be generated or downloaded by an upstream Task.

Note: This Task cannot be used to access a local file from your computer.

Recommended Setup:

A Workflow built with this Template should typically run after a Task that either downloads a file to Workflows or generates a file with code.
