Automate WooCommerce Order Alerts to Mattermost

What This Automation Does

This workflow watches your WooCommerce store for new orders.
When a new order appears, it gets the buyer name and first purchased item.
Then it sends a message to a Mattermost channel with that info right away.
This helps teams see new orders fast, without waiting or missing messages.
It saves time by removing manual notifications and speeds up order handling.

Common Edge Cases and Failures

• WooCommerce webhook does not send data: Usually webhook URL or settings are wrong.
• Mattermost message fails: Check channel ID and if API Key has right permissions.
• Missing order data: Make sure API access has read rights.

Customization Ideas

• Change message to add total price or email using expression:

= {{$node["WooCommerce Trigger"].json["billing"]["first_name"]}} bought {{$node["WooCommerce Trigger"].json["line_items"][0]["name"]}} for ${{$node["WooCommerce Trigger"].json["total"]}} ({{$node["WooCommerce Trigger"].json["billing"]["email"]}})!

• Add more Mattermost nodes to notify different teams.
• Include attachments like images or invoices in Mattermost messages.
