Shipping Document Service
FedEx Web Services can save you time and help optimize your shipping by creating many shipping documents for you. You will need to submit the required data elements in your Ship requests, including signature and/or letterhead images if desired. Before you can attach images, you must upload them (see Upload Images). FedEx Web Services will then create the shipping documents and return them in your Ship replies as Base64-encoded strings. You can also request that most shipping documents be sent electronically (see FedEx Electronic Trade Documents) instead of printing and attaching them to your shipments.
