Hey Support,

Email from UPS

"API Access Key Deprecation
On June 5, 2023 UPS began the sunset process for access key authentication in favor of the more secure OAuth 2.0 model for all APIs. This change impacts all API integrations and requires updates to your existing application interface. If your integration is managed by a 3rd party, please contact the provider. The migration guide linked below can help answer questions about the transition from access keys to OAuth 2.0"

I will confirm which one is installed and get back to you.

Hey Support,

I'm using the new UPS OAuth, but I'm getting an error in the frontend. I attached some screenshots.
Can you help me understand what is missing?

Hey Support,

Which one of the options do I need to choose to make the app works with the hikashop plugin? See screenshot.
- I want to integrate UPS technology into my business
- I want to integrate with UPS technology to represent many users

Hey Support,

Thanks for the help. I was able to add Rating, Authorization and the Time In Transit to the app. Now I'm getting a different error. I just want to know where do I need to change the Unit of Measurement to avoid this issue. See screenshots
