 The product validation is based on the API payload and the data stored in Voucherify's product inventory.
 
-However, if a product does not exist in Voucherify, the validation will use the product data included in the payload. Even if the product does exist in Voucherify, the payload data are used in the request. This way, frequent API calls can be avoided to keep the product inventory up to date.

 The `override` attribute is used to enable storing the product data in Voucherify. If the product does not exist, it will be created with a `source_id`. If the product does exist, the provided values for the name, price, and metadata will replace those already stored in Voucherify.
