Connecting Small Parcel to UPS
Small Parcel Suite allows you to connect your system to different shipping carriers, enabling you to manage your carrier information. One of the supported carriers of Small Parcel Suite is the United Parcel Service Inc. (UPS).
UPS has launched a new security protocol, oAuth 2.0, requiring your Small Parcel account to reauthenticate its UPS connection. This reauthentication must be completed by August 31, 2024, to prevent shipping disruptions.
This provides instructions on how to connect a UPS carrier account to the Small Parcel Suite. To learn more about the supported providers, features, and services, go to the Shipping with UPS article.
To prepare for the reauthentication of UPS connection, you'll need the following:

FAQ
What happens if I don’t update my information by August 31?
You won’t be able to connect or process labels or rates through UPS without updating this connection.
Do I need to do this if I have an existing UPS connection?
Yes, every customer with an UPS connection needs to go through this process by deleting their existing connection and reauthenticating by following the new process.
Does this affect what I am charged for my UPS shipments?
No, this change does not affect your rates with UPS. It only changes the authentication process for your UPS connection.
Does this apply to accounts that are billed 3rd party or only accounts used as prepaid?
If you are billing third party, the account that is being billed third party should be unaffected, however the prepaid account that is used as the shipper account will need to be reconnected.
Does this apply or affect the billing of my accounts?
This change only affects the connection to UPS. Billing is unaffected by this update.
Why do I need to ask for my customer’s UPS credentials to set up connections?

Does this affect my use of the APIs for 3PL Warehouse Manager?
This change only affects the connection to UPS. Other API usage isn’t affected.
