This blog post addresses a crucial update announced by UPS regarding their API authentication process. Starting June 3, 2024, UPS will be migrating from the legacy access key model to a modern OAuth 2.0 security standard. This shift aims to enhance security, minimize fraud, and streamline API usage.

What Does This Mean for You?

This update impacts Magento users who utilize UPS shipping integrations. Here’s a breakdown of the changes and how they affect your store:

Changes Happening:

• Deprecation of Access Keys:
  • No new access keys will be issued after June 5, 2023.
  • All API calls using the old access key method will cease to function after June 3, 2024.
• RESTful API Adoption:
  • UPS APIs are transitioning to a true RESTful structure, allowing for greater flexibility and simpler integration.
• Bearer Token Authentication:
  • Replacing the previous method of including credentials within the API request body, a bearer token will be used in the Authorization header.

The Benefits of OAuth 2.0

• Enhanced Security: Improved protection against unauthorized access and reduced fraud risks.
• Simplified Integration: Streamlined integration process for third-party software providers like Exinent.
• Flexible API Management: Dynamic updates to API payloads without strict schema maintenance.

Understanding OAuth 2.0

OAuth 2.0 is an authorization and authentication protocol widely adopted across web applications. It utilizes access tokens issued by an authorization server to verify and authorize API requests. This model safeguards against credential theft and misuse, fostering a more secure environment for transactions.

How Bearer Tokens Work

Think of a bearer token as a string of characters representing your application’s authorization to access UPS services. This token resides within the Authorization header of an API request and has a defined lifespan. New tokens must be obtained before the current one expires.

Client Credential vs. Authorization Code Flow

Two primary OAuth 2.0 flow options exist:

• Client Credentials Flow: Suitable for application-to-application authentication scenarios where your application uses a single UPS username for transactions with UPS. No user interaction is required.
• Authorization Code Flow: Ideal for user-to-application authentication. This flow enables users to leverage their own UPS credentials within your application for transactions.
