Frequently Asked Questions About our Shipping API

Our tracking endpoint allows you to track shipments with generalized LSO status and substatus tokens. When combined with webhooks, you will get push-style updates anytime a tracking update occurs. Visit our tracking page for more information.

Validating addresses is easy. Simply add a parameter validate: true to your Address POST request. You can validate global addresses just like U.S. addresses. The key difference that you’ll notice is in the response that you get back.

You can find your LSO Test Token from the API section of your dashboard. To turn on test mode, insert your LSO API Test Token in place of the Live Token. Now you can use LSO as you would in production and be sure that you won’t get charged. For more information, check out our API test mode page.
