Mechanic is a development and ecommerce automation platform for Shopify. :)
Useful for digital products, memberships, or anything else that needs to be fulfilled instantly. This task watches for paid orders, and auto-fulfills all line items that don't require shipping.
Runs Occurs whenever an order is paid and Occurs when a user sends an order to Mechanic. Configuration includes include products with any of these tags, exclude products with any of these tags, and wait until any other shippable items are fulfilled.
Useful for digital products, memberships, or anything else that needs to be fulfilled instantly. This task watches for paid orders, and auto-fulfills all line items that don't require shipping.
Optionally, choose to include or exclude products by tag, and wait until other shippable items are fulfilled, if any.
Note: exclusion tags on a product will take priority over inclusion tags.
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.
(By the way, have you seen our documentation? Have you joined the Slack community?)
