Because security vulnerabilities have been identified in early versions of TLS (1.0 and 1.1), Pitney Bowes is upgrading the protocol used to secure all external connections made to our systems. Beginning on August 23, 2018, TLS 1.2 will become the minimum supported communication protocol.
Pitney Bowes has enabled a testing environment to aid in this update process. Use this environment to verify that your servers support TLS 1.2, curl-X GET: https://api-test.pitneybowes.com/tlstest
The testing environment will generate a "TLS Connection Success” message if your TLS update is successful.
Thank you for your cooperation and assistance with this important update.
