> 
> A workflow post function that sends a message to Slack - to selected channel or channels, or to specific users.

> ℹ️ **Note**: To utilize this post function, there are a few considerations outside of JMWE: 
> ℹ️ 
> ℹ️ 1. Use of this post function requires the free Slack app **Notifier by Appfire**. You will be prompted to install this app on Slack the first time you connect JMWE to your Slack workspace.
> ℹ️ 2. You must be an administrator of the Slack workspace to which you want to send messages; workspace administrator permissions are only required when connecting JMWE to a workspace, not for sending messages to a workspace.
> ℹ️ 3. You only need to connect to a workspace once.

> 📝 **Note**: The **Send Slack message** post function does not include configuration options to Run As any user other than the app user; this is due to permission requirements within Slack when using the **Notifier by Appfire** app.
