eBay .NET API, Adding Listings, Unexpected number of Return Polices Have Been Created.

[znts-wholesale-global]

I am using .Net SDK for eBay, I am creating products and assigning return policy as per code before.

private static ReturnPolicyType GetReturnPolicyForAU()
{
ReturnPolicyType policy =
new ReturnPolicyType
{
Refund = "MoneyBack",
ReturnsWithinOption = "Days_30",
ReturnsAcceptedOption = "ReturnsAccepted",
ShippingCostPaidByOption = "Buyer"
};
return policy;
}

and I use it this way

item.Location = product.Location;
item.PostalCode = product.PostCode;
item.DispatchTimeMax = 5;
item.ShippingDetails = defaultItem.ShippingDetails;
item.ReturnPolicy = GetReturnPolicyForAU();

but in my business policies, It has created many polices,

Business policies are newer than the older ReturnPolicy field.

And when a listing is created in some way that doesn't specify one of the existing policies by a given name or ID, one instead gets generated.

To use them in the Trading API (when predefined) you use Item.SellerProfiles followed by .(SellerPaymentProfile/SellerShippingProfile/SellerReturnProfile) and then either Name or ID of the policy (yes, policy/profile wording is a bit mixed) (ID takes precedence when both are present)

template:

    <SellerProfiles> SellerProfilesType
      <SellerPaymentProfile> SellerPaymentProfileType
        <PaymentProfileID> long </PaymentProfileID>
        <PaymentProfileName> string </PaymentProfileName>
      </SellerPaymentProfile>
      <SellerReturnProfile> SellerReturnProfileType
        <ReturnProfileID> long </ReturnProfileID>
        <ReturnProfileName> string </ReturnProfileName>
      </SellerReturnProfile>
      <SellerShippingProfile> SellerShippingProfileType
        <ShippingProfileID> long </ShippingProfileID>
        <ShippingProfileName> string </ShippingProfileName>
      </SellerShippingProfile>
    </SellerProfiles>

To manage / create them using API instead of the website, you have to use the REST Sell API Account v1. (Payment/Fulfillment/Return)
