Mechanic is a development and ecommerce automation platform for Shopify. :)
This task illustrates Shopify's recommendation of implementing reconciliation, in the case of missing Shopify events. This implementation handles the rare case that Shopify fails to deliver a webhook (orders/create, in this example), by scanning for unprocessed orders every 15 minutes.
Runs Occurs whenever an order is created, Occurs every 15 minutes, and Occurs when a user manually triggers the task. Configuration includes run on order create, reconcile every 15 minutes, and reconcile on manual run.

To learn more about this kind of scenario, see https://learn.mechanic.dev/core/shopify/events/reconciling-missing-events.
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.
