As of April 13th any members using the 2.0 release candidate schema will be required to use https in calls to the ORCID API. In calls to post to, put to, or read ORCID records the URL must start with https. For example when reading the activities on a record the URL is https://api.orcid.org/v2.0_
Using https improves the security of the ORCID API and we encourage all integrations to use the https urls, but we will continue supporting http on version 1.2. This change only affects the API, ORCID identifiers will still be access able online with http, such as https://orcid.org/0000-0001-5109-3700.
