Mechanic is a development and ecommerce automation platform for Shopify. :)
Upon the fulfillment of an authorized or partially paid order, this task attempts to capture all open authorized payments for that order. (Multiple authorizations can exist on edited orders or with post-purchase upsells.)
Runs Occurs whenever an order is fulfilled.
Upon the fulfillment of an authorized or partially paid order, this task attempts to capture all open authorized payments for that order. (Multiple authorizations can exist on edited orders or with post-purchase upsells.)
If the order is modified before capturing, due to applying discounts, changing shipping fees, and/or making item adjustments, then this task will only capture up to a maximum of the current order total.
For expected results, be sure to enable "Manually capture payment for orders" in Shopify, using this guide.
Please note: You are responsible for ensuring that fulfillment occurs within the order payment's authorization period.
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.
