Connect UPS

Create a UPS Developer Portal app with OAuth + Rating, copy Client ID/Secret and account number, then connect in Net3000.

Connect UPS so Storefront3000 can calculate live shipping rates at checkout.

In Net3000 admin, open Integrations → UPS (/apis/Ups).

Open the UPS Developer Portal

Log in at developer.ups.com with your UPS.com account, then open My Apps.
Add an app and select products

Click Add Apps. Choose I want to integrate UPS technology into my business, associate your UPS shipper / billing account, accept the API agreement, and continue. Name the app (for example “Net3000 Storefront”), then include at least:
- Authorization (OAuth)
- Rating (required for live checkout rates)
Save the app.
Copy Client ID, Client Secret, and Account Number

Open the app details under My Apps and copy the Client ID and Client Secret. Also note the UPS Account Number you associated with the app.
Paste into Net3000

Open /apis/Ups, enter Client ID, Client Secret, and Account Number. Enable Use sandbox (CIE) for testing. Click Save.
Verify rates at checkout

Place a test order in Storefront3000 and confirm live UPS rates appear during checkout.
