Mechanic is a development and ecommerce automation platform for Shopify. :)
This task generates a brand new discount code (copying configuration from another code, of your choice), and emails it to the customer, after waiting a configurable number of days after order fulfillment.
Runs Occurs whenever an order is fulfilled, with a 14 day delay. Configuration includes days to wait after order fulfillment, source discount code for cloning, override source with this discount validitity period in days, new discount code prefix, email subject, email body, and email bcc.
This task generates a brand new discount code (copying configuration from another code, of your choice), and emails it to the customer, after waiting a configurable number of days after order fulfillment.
Configure this task by first creating a discount code in your store, representative of the discount configuration you'd like this task to use. Provide the task with this source discount's code – when it runs, the task will clone this discount's configuration, using a new and unique discount name.
Configure with a number of days to wait after fulfillment, or remove this value completely to have the discount generated and sent immediately upon fulfillment.
Use the text "DISCOUNT_CODE" to have the generated discount code inserted into your email to the customer, in either the subject or body.
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.
