Hi Scotti, Our organization is considering the same kind of integration (ShipExec). According to Ups, we have 2 options on how to go about this. Do we make E1 the driver (or initiator of rating process) suggesting procedure calls to ShipExec Api <<OR>> use the Ups Thin Client to drive process. We’re leaning towards the Thin Client. I welcome any information and advice you might have for us. Thanks in advance for your time. -John S
