Hello all!
I am trying to integrate Octoslack into a Slack Workspace that does not have bots/custom applications available. I was experimenting with a Workflow Webhook, but can't seem to pass variables from Octoslack to it. I can get Octoprint to post a generic message in a Slack board whenever the printer performs GCODE. Any time I add a variable to the Slack Webhook, I begin getting HTTP error 400 due to Octoslack using different variables.
What variables do I add to my Slack Webhook (included screenshot) to make this work?
