Does CMS Max still use the legacy UPS Developer Kit?

The current CMS Max shipping architecture connects UPS as a carrier through Shippo. The page no longer instructs merchants to build against the legacy Developer Kit as a separate storefront project.

Do I need to create a UPS API application?

UPS states that customers using third-party applications generally do not need their own API credentials. The relevant UPS account must still be associated, eligible, and connected through the current Shippo workflow.

Can CMS Max show negotiated UPS rates?

Eligible account-specific pricing may be returned when the connected UPS and Shippo account relationship supports it. Verify with representative shipments and reconcile against actual UPS invoices.

Can I show only selected UPS services?

Yes. CMS Max Shippo settings support allowed-carrier and service-level filters. Returned options still depend on the account, origin, destination, parcel, and current carrier response.

Does CMS Max support UPS labels and tracking?

The Shippo-backed workflow supports eligible carrier label operations and normalized tracking data. Confirm the exact services, label formats, account requirements, and production behavior during testing.

Why might the final UPS charge differ from checkout?

Carrier invoices can reflect measured dimensions or weight, address corrections, residential and fuel surcharges, additional handling, pickup, service changes, and other adjustments not present in the original request.
