UPS TLS 1.2 Upgrade SSL Connection Issues¶

On January 19th UPS sent out a tech alert email stating that they were going to reject all requests to their API that were not TLS 1.2 compatible.

UPS is in the process of upgrading communication security protocols for all web-based applications, including UPS Developer Kit Application Programming Interfaces (APIs), which are used to integrate UPS functionality into your website and applications.

Effective January 26, 2016, the UPS test environment will require the TLS 1.2 security protocol, and will be available for your system testing.

Effective May 31, 2016, UPS will require the TLS 1.2 security protocol in production. After that date, any communication requests submitted to UPS using older protocols (TLS 1.1 or earlier) will fail.

NOTE: From January 19 through May 31, 2016, you may see intermittent failures for any non-compliant transactions.
