Part 1: Setting Up a Webhook
A Slack webhook is used to not only see PrismAIO success, but also required to receive PayPal checkout links.
Create your own Slack Workspace by clicking the "+ - Add workspaces" Icon the left-hand side of your slack application
Once you have created your new workspace, you should be on the homepage for the workspace in your internet browser.
Scroll to the bottom and locate the "+ Add Applications" button.
Locate the application "incoming Webhooks" and add it to your workspace
Once the application has been added, click on the application and go to the settings tab to edit your configuration.
Pick a channel that the app will post to, then click Authorize.
You can finally click generate in the Webhook URL box to generate your slack webhook link.
Copy and paste that same link into appropriate box in the PrismAIO settings tab.
