This method syncs a shipped sale and auto-removes quantity. If the product is in multiple locations, then the remove will occur at the location that is first in alphanumerical order. Quantity can be removed from normal, Reserved, and Backstock locations.
If your account has AutoRemove enabled, then syncing sales using this call will result in the system attempting to remove sale item quantity twice. Please use with caution and if you are unsure if this warning applies to your account, please submit a support ticket here.
