Accessorials are additional services applied to a shipment. Pass them in the charges array of your rate request.
LTL accessorials
arrival notice and arrival schedule are mutually exclusive. Include one or the other, not both.
Facility type charges
Location-based charges (residential delivery, trade show, limited access, etc.) are applied automatically based on the originType and destType fields. You do not need to list them as accessorials.
For example, setting destType: "residential" automatically adds the residential delivery surcharge.
