Description:

The paymentservice_check_existing() function determines whether a subscription digital good is currently active. Only the ID or SKU of the digital good is required as input in order to retrieve the subscription status of a digital good. If both are provided, then the ID takes precedence, and the SKU will only be used in case the digital good cannot be retrieved using the ID.

Returns:

BPS_SUCCESS upon success, BPS_FAILURE with the errno value set otherwise.
