In 2024, UPS introduced a new way to verify API users by switching to OAuth 2.0. This change replaced the older system that relied on access keys to authenticate users and is a more secure method. Along with this, UPS has transitioned to a modern REST API, which requires customers using UPS services to update their integrations to align with the new standards.

In nShift Delivery, we have added the following revised services to support the new API and authentication method:

• UPS Expedited revised
• UPS Express Plus revised
• UPS Express revised
• UPS Express Saver revised
• UPS Ground revised
• UPS Standard revised
• UPS World Wide Economy DDP revised
• UPS World Wide Economy DDU revised
