If your store supports a loyalty program, you use the Admin REST API to create a currency that represents loyalty points. Then you create and activate a price group for the points, just as you would any other currency your store supports. See Work with Loyalty Programs in Extending Oracle Commerce Cloud for details about creating a currency for loyalty points and assigning it to a price group.

If your store uses one of the built-in tax-processor integrations (Avalara AvaTax or Vertex O-Series), you can use the REST Admin API to convert the value of points-based orders to monetary currency so that your tax processor can calculate taxes for the order. (See Work with Loyalty Programs in Extending Oracle Commerce Cloud for more information.) or you can turn off tax calls for the points-based price group and make sure tax processing is handled externally, for example, in your order management system. (See Create and edit price groups for more information about configuring tax settings for price groups.)
