Worldwide Express and Unishippers: Missing Checkout Rates

Learn why Worldwide Express and Unishippers LTL freight rates may be missing at checkout due to slow API responses and what can be done to resolve the issue.

Overview

Merchants using Worldwide Express or Unishippers (collectively known as WWEX Group, also operating as ShipStation Global) may experience slow API response times when requesting LTL freight quotes. When responses take too long, shipping rates may not appear on the e-commerce checkout page, even though rates are available when obtaining quotes directly from the shipping provider's website.

This article explains why these delays can affect checkout and the possible remedies.

Why API Response Times Matter

E-commerce platforms impose time limits on how long they will wait for shipping rates during checkout. These limits help ensure that shoppers are not left waiting indefinitely for shipping options.

When WWEX Group takes too long to respond to an API request, its LTL freight rates may not be received in time to be displayed on the checkout page.

Possible Solutions

WWEX Group has identified several approaches that may help reduce API response times. These changes must be made to your account by WWEX Group.

Important: Disabling a carrier on the app's Carriers settings page does not prevent WWEX Group from including that carrier in its API response. It only prevents the carrier's rates from being considered for display at checkout. To improve API response times, carriers must be excluded from the API response by WWEX Group.

  1. Remove Southeastern Freight Lines (SCAC: SEFL) and XPO (SCAC: CNWY). Recent changes to how WWEX Group obtains rates from these carriers have increased response times. Removing them from your account may help mitigate the problem.
  2. Limit the number of carriers to 10. Reducing the number of carriers enabled on your WWEX Group account may improve API response times.
  3. Return only rates received within a suitable amount of time. WWEX Group may limit API responses to carriers that have returned rates within a specified time, rather than waiting for all carriers to respond.

Contact your WWEX Group representative to discuss which remedies are available and appropriate for your account.

Important Consideration

These methods may result in some carriers being available when obtaining quotes directly through the shipping provider's website but not appearing as shipping options on the e-commerce checkout page.
