Customers and adjustments
Customers lists everyone with points, by most points or most recent activity. Choose a customer to see every change: orders that earned points, refunds, conversions and adjustments.
To add or remove points by hand, choose Adjust points, find the customer, enter the points (a negative number removes them) and a reason. The reason shows in their history.
Each customer's balance and their latest ten changes are also saved on the customer in your store, read-only, under the app's metafields.
