The PriceRule resource now supports an allocation limit
API
Effective September 10, 2018
Action required
We're adding a highly requested new parameter to the PriceRule API: allocation_limit. This new parameter represents the number of times a discount can be applied to the cart, if eligible. This additional parameter will only be available for Buy X Get Y discount types.
For example: If a “Buy 1 Get 1 For Free” discount has an allocation limit of 2, then the discount will only be applied to the cart twice, even if there are more than 4 items.
If no allocation_limit is specified, the discount will default to unlimited uses in a single cart. If your app doesn't use this new parameter, then all discounts will have unlimited uses.
Apps that have created a Buy X Get Y discount type have been notified via email to their Partner account. If your app is creating these discounts and you have not received the email, then reach out to deprecations@shopify.com.
Starting today, you can request this parameter be enabled for your application by emailing deprecations@shopify.com. On September 10, 2018, the parameter will be active for all applications.
