Minimal Requirements Checklist

• Use OAuth to authenticate ORCID iDs (Do not allow users search for or type in ORCID iDs.)
• Include an ORCID branded button or link on your site to initiate authentication of the iD.
• Present the OAuth authorization screen according to our guidelines
• Use HTTPS for your site’s redirect URIs and on ORCID API calls
• Accept and store all data returned in the token exchange together with the user’s data in your system
• Use appropriate scopes and request methods (e.g. POST calls to add new information and PUT calls to update existing information)
• Publicly display the authenticated ORCID iDs. iDs should be displayed following our trademark and iD display guidelines.
