• Create a new manifest.
• You must set the “Location Code” as all shipments must have the same ship from address.
• You must set the “Shipping Agent Code” to the USPS entry.
• Use the “Get Shipment Documents” action.
• You will be presented with a list of License Plates that match the location and shipping agent criteria. Select all that you wish to manifest.

• Unable to create manifest. 1 of the specified shipments were not found: shp_xyz123

USPS manifests all shipments automatically at 17:00 Pacific Time. Those shipments can no longer be manifesting by the system. You must remove them from the manifest to continue. You should not rely on this auto manifesting as you cannot retrieve the corresponding manifests. You can attempt to avoid this by selecting only shipments from the current day, not previous ones.
