Support Ending for TLS v1.0 and v1.1- Immediate Action Required
The Constant Contact API, managed by TIBCO’s Mashery, will no longer support TLS v1.0 or v1.1 when establishing secure connections as of September 30th, 2018. We recommend updating your integration to TLS version v1.2 to comply with security practices outlined by thePayment Card Industry (PCI) SecurityStandard Council.

Our SDKs are libraries that make it easy for you to make calls to our API. The calls themselves are run from your server with your own framework, so there is no update needed to the SDK directly. Because each web server and application is different, I'm not able to provide you with specific directions on how to make sure everything on your server is up to date. I would recommend reaching out to your hosting provider for detailed steps on how to check or upgrade your TLS compatibility.
