UPS Account Connection Instructions

Last updated: October 20, 2026

To connect your UPS account to Corksy, you’ll need your UPS account number, Client ID, and Client Secret from a UPS Developer account. Follow these steps to create the app and retrieve them.

  1. Go to the UPS Developer portal and click Create an Application.

  2. Log in to your existing UPS account or create one.

  3. Click Add Apps.

  4. For “Tell us about your API needs,” choose “I want to integrate UPS technology into my business” and select the account to associate with these credentials. Click Next.

  5. Fill in your Primary Contact information and click Continue.

  6. Add your App Details:

    • App Name: Corksy

    • Callback URL: your website URL (including https://)

  7. Add Products — add all of the following, then click Save: Authorization (OAuth), Address Validation, Locator, Rating, Time In Transit, Tracking, and Shipping.

  8. Accept the UPS terms & conditions.

  9. UPS will provide your Client ID and Client Secret.

  10. In Corksy, go to Settings → Shipping & Delivery → Connect account (UPS) → Integration type: New.

  11. Enter your UPS Account Number, Client ID, Client Secret, and Callback URL, then click Save.

If you see "Missing or invalid shipper number"

This usually means the UPS Account Number in Corksy is missing or wrong, or the UPS app your Client ID and Client Secret come from isn't linked to that account number. In the UPS Developer portal, check that the app is linked to the right UPS account. Then in Corksy go to Settings → Shipping & Delivery → Connect account (UPS) and enter the UPS Account Number, Client ID and Client Secret again.
