This should be dynamic based upon the shipper destination. Many customers will provide the option of Next Day, 1-2 days, 3-5 days shipping options. The service type shipped will vary based upon the destination. 2---Address Validation API: Determine if the address entered by the customer is correct. Will help avoid any address correction fees or missed deliveries. 3---Quantum View API: Allows your customer to be able to track their packages through their login directly on your site instead of going to [login to view URL] to track their package. This helps drive more page views to your site and can help generate return business. 4---UPS to USPS - called “sure post” 5---Rating API: Allows you to provide as many or as few services options as possible (Ground and Different Air Services). You can also determine what rates you would like to charge the customer. Published rates, negotiated rates or a custom rate.
