Auto-tag orders that do not have a certain tag, with Mechanic.

Mechanic is a development platform for Shopify. :)

Auto-tag orders that do not have a certain tag

This task monitors for new and updated orders, adding a tag if a certain other tag is found missing. If and when the order does receive that certain other tag, the task's tag will be removed.

Runs when an order is created and when an order is updated. Configuration includes order tag to watch for and order tag to add.
