The ApplicationCredit resource is used to issue credits to merchants that can be used towards future app purchases in Shopify. You can create an application credit by sending a request that includes the credit amount and a description explaining the reason for the credit. A corresponding deduction based on your revenue share is entered in your Partner account by Shopify. For example, if you create a credit for $10.00, then a deduction of $8.00 is applied.
The total amount of all application credits requested by an app must not exceed the total amount the shop owner was charged in the last 30 days, or the total amount of pending payouts in the app's Partner account.
