Mechanic is a development and ecommerce automation platform for Shopify. :)
Use this this task to monitor for the addition of a specific customer tag, and to schedule the customer to be untagged a configurable number of days later. Useful for granting temporary access to discounts, or other resources.
Runs Occurs whenever a customer is updated and Occurs whenever user/task/untag_customer is triggered. Configuration includes tag to monitor and days to wait before untagging.
Use this this task to monitor for the addition of a specific customer tag, and to schedule the customer to be untagged a configurable number of days later. Useful for granting temporary access to discounts, or other resources.
As soon as that tag is detected, the task will add a second tag, indicating that the customer is scheduled to be untagged. (For example, if the task is configured to watch for the tag "Approved", the task will add the tag "Approved - will be auto-removed by Mechanic".) The task will then schedule a followup event for the future, according to the configured number of days to wait. At that time, the task will remove both tags.
Important note: To prevent the task from untagging the customer later, manually remove the task's additional tag (i.e. the "will be auto-removed by Mechanic" tag).
Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Shopifolks, everybody.
That’s why we make it easy to configure automation without code, why we make it easy to tweak the underlying code once tasks are installed, and why we publish it all here for everyone to learn from.
