    How can shipping API help my business?

    Shipping API can bring different benefits to any business that requires regular shipping of parcels and pallets. Some of the effects are listed below.

    Less undeliverable shipments

    Retyping receivers address into an additional software is not only cost-beneficial but is prone to errors which can cause shipping delays or undelivered shipments. Using Shipping API, you do not have to worry about that as real-time direct data transmission and validation assure that those mistakes do not happen.

    Use only your system

    If your business uses Shipping API, you will not need to train your staff to use the shipping provider's web application.

    Customize shipping label

    You may want to brand the shipping labels with your logo or use some special shipping label size. This is all possible, as Shipping API produces fully customizable shipping labels of any size.

    Receiver database maintenance

    As opposed to the usage of Internet Shipping which offers you the usage of the standard address book, Shipping API uses the data you provide it. So, if the shipment receiver changes the address, you will need to update it in your system only as Shipping API creates shipping documents based on the.

    Getting started

    Is very easy. It's strongly recommended that you read through this entire document. After you have finished getting this information, please consult Support contact details for any inquiries you might have.

    Access to Shipping API

Access is granted by provisioning a valid shipping API key by a parcel shipping company. If you require access to the Shipping API, please contact your sales representative.

    The access is granted to Provisioning of new API keys Customer is granted access to a Shipping API by generating an API key via the Shipping API administration interface. A customer is referenced by the customer account number from the cargoNET system (customer ID) in the Shipping API administration interface. It is recommended that the Shipping API administration user interface is visible only from within a shipping company network. The decision process of when access to the Shipping API via an API key is granted to a customer is handled by a shipping company.

    Maintenance and downtime

    Being the core business application, Shipping API maintenance and downtime is carefully planned. Most of the updates are scheduled for outside of regular business hours whenever that is possible. The technical personnel of Shipping API users will be notified of any planned longer downtime by posting such information on the official shipping provider's website. In case of ad-hoc maintenance or downtime, technical contact will not be notified if downtime is shorter than 30 minutes.
