Understanding the Structure of the Reorder Flow
As shown in the diagram above, the reorder flow has the following elements:

(i) A trigger that defines when to start the flow and for which product. The trigger for this flow is an order confirmation. The flow can be triggered for all variants of a product or a particular variant of the product.
(ii) A time delay that can be defined by you.
(iii) A message that will be triggered after the time delay with a Buy Now button to take the customer to the checkout page of this product.
