HTTPS at NCBI: Guidance for NCBI Web API Users. NLM Tech Bull. 2016 Jul-Aug;(411):b5.
2016 July 28 [posted]
On September 30, 2016, NCBI will move all Web services to the HTTPS protocol to meet the Federal HTTPS-Only Standard directive for Federal Web sites and services. While this move will improve security and privacy, it may also disrupt any processes that currently access NCBI APIs using the HTTP protocol.
Please see, HTTPS at NCBI: Guidance for users of NCBI Web APIs, on the Develop action page for a complete discussion of this move and what you need to do, along with some new test servers to help you confirm whether your code will function after the change to HTTPS.
