Best Practices and Troubleshooting

Best Practices


The best practices specific to YubiEnterprise APIs are in the API: Best Practices and FAQs section of Shipping Request Via API.

  • Have at least two Org Owners who can manage members (see User Management).
  • Inform both your YubiEnterprise users and your end-users in advance that they will receive email from Yubico’s YubiEnterprise Delivery. Without this advance notice, they are likely to regard these emails as phishing attempts.
  • If YubiEnterprise appears to be behaving strangely, check the status of Yubico services:
  • Subscription customers:
    • To ensure that you do not let keys in any of your inventories expire unused, create a spreadsheet to plan the allocation of products across users and inventory types. See Example Subscriptions.
    • When creating a shipment request, select the inventory type before selecting the item(s) to be shipped.

Limits and Constraints

When planning and executing shipment requests, keep in mind the primary limits and constraints set out in Delivery Policies, but also the following:

Although the system can deliver to Post Office (PO) Boxes within the United States, delivery to the equivalent elsewhere in the world is unlikely to succeed.

The entity through which you submit a PO is always referred to as a channel partner. “Channel partner” is a term that covers distributors, resellers, and even Yubico itself. Yubico’s Channel partner ID (or ChannelPartnerId or channelpartner_id) is “1”.


The selection of channel partner is not supported in the /shipments API.

Because inventory is sorted according to the source from which it was purchased, when requesting shipment, distinguish between inventory purchased directly from Yubico and inventory purchased through distributors and resellers doing business with Yubico. The Dashboard shows your total inventory of any given product, combining quantities purchased from all sources: both directly from Yubico and indirectly through channel partners. To find out what is in which inventory, check your purchase orders.

To find out what the channel partner (reseller or distributor) ID is:

BEFORE shipment:

The name of the channel partner (reseller or distributor) is shown on the Purchase orders tab, and the channel partner ID is shown on the PO detail popup accessed by clicking on the Purchase order number:

AFTER shipment:

The Channel partner ID (Reseller or Distributor) is shown on the shipment request detail page, accessible by clicking the ID of the shipment request on the Shipments tab.


First Line

In the Console, First name and Last name and in the CSV file, recipient_firstname and recipient_lastname map to the first line on the shipping label.

Long recipient names can be problematic for all methods of requesting shipment, because the shipment request will fail if the contents of the First name / Last name fields and/or Company or recipient fields exceed the maximum number of characters permitted in these fields (shown in the table below). Workaround: When a recipient’s full name or company name exceeds the fields’ maximum lengths, split the names across the three fields, for example:

Location Field (limit=15) Limit Field (limit=20) Limit Field (limit=20) Limit
API recipient_firstname 15 recipient_lastname 20 recipient 20
CSV recipient_firstname 15 recipient_lastname 20 recipient_company 20
Console First name 15 Last name 20 Company 20
Example of an overly long name before adjustment to fit the fields
  Johannes-Maximilian   von Derschowitz-Dampfloch zu Querdenker
Example after adjustment
  Joh.-Maximilian   v.DerschowitzDampfloch   zu Querdenker  

Second Line

The second line on the shipping label maps to the name of the recipient’s company if the address is not residential. For example, the system’s address verification function recognizes that Yubico’s Santa Clara facility is in a commercial building, therefore the company name is expected in:

  • The Company field in the Console

  • The recipient_company column in the CSV.

  • The recipient field in the API


    API: Do not use the /shipments recipient field to specify the name of the individual to whom products are to be shipped. For this, use the recipient_firstname and recipient_last name fields instead.

If the address is residential, leave empty:

  • The Company field in the Console
  • The recipient_company cell in the CSV file
  • The recipient field in the API.
Examples of Bad Usage of Company Name Field

For example, entering the following information for a shipment request would result in failure because USPS recognizes that there are multiple companies in the building whose address is 530 Lytton Avenue:

Jan Lindberg
530 Lytton Avenue
Palo Alto, CA 94301

Similarly, entering the following information for a shipment request would result in failure because a residential address would not be associated with a company.

Jan Lindberg
Yubico Inc.
6 Lea Rd
Dronfield S18 1SB

Address validation takes place every 15 minutes. This means that you might have to wait up to 15 minutes to find out if your shipment request has been queued for fulfillment (see Shipping Status Codes).

Non-subscription purchases: Shipment requests can be made for up to one year after a PO is submitted.

Subscription purchases: Availability of products in shipment requests depends on the stock/inventory from which the products are drawn. (For details, see Tier Sub-categories.)

The full list of options that were potentially available in Subscription (1.0) is given below. The actual list depends on what you have purchased. Explanations for the terms in the list are given in the table below the list. For more details on subscription and non-subscription purchasing, see Modes of Purchase.

For Requests:

Shipment requests can be edited or deleted until 2am PST (10am GMT), the day after they were entered. For instructions on these procedures, see Editing or Deleting a Shipment.)

For Delivery:

Normal (standard) shipping: Typically, shipments will take 5-7 days for delivery in North America and Europe. Delivery to other parts of the world will take longer.

Expedited (rush) shipping: Typically, shipments within North America can be delivered in 1 business day. It may take longer to deliver shipments to other parts of the world, but Yubico will leverage the fastest delivery service reasonably available.


This section addresses issues that can arise with shipping. YubiEnterprise Delivery notifies you of the situation of any given shipment via the codes in the Status column of the Shipments tab. The table below, Shipping Status Codes, lists the error codes and their explanations.

YubiEnterprise Delivery uses address validation services to reduce the incidence of issues, but it is important to be aware that just because an address exists in Google Maps, it does not mean that the address is deliverable. ‘Deliverable address’ is a United States Postal Service (USPS) classification for designating addresses to which the USPS has historically been able to deliver. YubiEnterprise Delivery’s ability to deliver is based on address information being input in the format acceptable to the relevant address validation service. The USPS-acceptable formats are set out in detail in the USPS’s Postal Addressing Standards.


When revising an address, the best option is to use the format Google Maps presents, because it usually does use the address format preferred by the validation service. In the example below, the address format that was input appears in the upper field, and Google Maps’ format is shown below the photo of the location.


Address Validation Outside the US and Canada

For parts of the world with less standardized address formats, the fact that YubiEnterprise Delivery can accept an address does not mean that it is deliverable. An address will often be classified as “partially deliverable”, which means that we rely on local couriers who are familiar with the complexities of their urban systems and their delivery routes to deliver to the intended recipient.

Typically packages sent to European addresses and some parts of Asia reach their destination. Packages sent to Southeast Asia and Eastern Europe typically arrive at the right street. In those parts of the world where there are no numbers in the postal addresses, the local courier’s capability is crucial to ensuring that the package actually arrives at its destination as opposed to ending up in its general area.

Shipping Status Codes

At any of the states between 1 and 9, a shipment request can be edited. From this point on, a shipment request is either processed through to an end state, or set back to state 99.

(4) Any shipping request with a recipient name and/or address found on the US government’s DPL (Denied Parties/Persons List) cannot be fulfilled.

Shipment Status Messages

These error messages accessible via the API tell you why a given shipment request was unsuccessful. It is worth reviewing them before making any shipping requests in order to see what sort of issues might arise and thereby avoid them in the first place.


As the following table is wide, you might need to scroll horizontally.

In the Explanation column, the source of the message is given: YubiEnterprise Delivery system for internal messages, US Validation for the US Postal Service, and finally, International Validation. Messages originating from the last two are simply passed on to you by YubiEnterprise Delivery.

Insufficient Inventory

To maintain the window during which orders can be updated, edited, or recalled/deleted, orders are held and processed in batch. Therefore there might be less inventory available by the time an order is processed than what was shown in purchase order details when the request was created. For example, the person starting to create a shipment request assumes that the 50 keys the console shows they have in inventory will still be available by the time the shipment request is submitted. When this is not the case, any shipment requests processed after the inventory is exhausted will be flagged with this error message:

Error: Processing Error, contact support.
Reason is Not enough Inventory for Shipment
- ShipmentStateError

A second issue arises from the same source: when the user clicks on the shipment request ID with that error, part of the status message displayed is “Insufficient Inventory of Product X” where “X” is an integer. To find out what X means, consult the Product Name, Stock/Inventory, product_id and inventory_product_id table.

A third issue arises from the same source: it is not possible to make single shipment requests for products that are not available in inventory - which is expected if insufficient product has been purchased, but an insufficiency of inventory can also be caused by Yubico itself running out of stock.


Either contact Support to get more inventory, or edit the request to switch to another product for which inventory is available.
