Register a public API client application

Access to the ORCID Public API requires a set of credentials consisting of a Client ID and a Client Secret. This guide describes the steps needed to obtain ORCID Public API credentials. ORCID members need not register for the public API as their member credentials can be used instead. To register for member credentials see Register a client application

Public API credentials are tied to an individual's ORCID record and cannot be transferred to another person. Organizational API credentials are available to organizations that support ORCID through a paid membership subscription. Learn more about ORCID membership.

We recommend that developers test the Public API in the sandbox testing server before using the production version. Once tested in the sandbox environment, you can follow the same steps below to obtain credentials for the production environment.

For more general information see the Public Client ORCID API.

Enable developer tools

  1. Log into your ORCID record at (or, if testing in the sandbox).
  2. Click Developer Tools at the top of your record.
    Note: In order to access Developer Tools, you must verify your email address. If you have not already verified your email address, you will be prompted to do so at this point.
  3. Click the "Register for the free ORCID public API" button

    Name, description, and website: Information about the application that you are developing; these values will be displayed to users.

    Redirect URIs: URIs for use with the OAuth 2.0 protocol; Public API applications must have at least one redirect URI registered, and the URI must begin with http or https. For testing, you can automatically add Google OAuth Playground URI by clicking "+Google OAuth2 Playground" under Test redirect URIs. For more information, see About redirect URIs.

  2. Click the Save icon at the bottom of the form to generate your API credentials.

  3. To view your API credentials, click Show Details.

  4. Your API credentials - Client ID and Client Secret - are shown just beneath your redirect URIs. Below your credentials are sample URLs and API calls with your credentials pre-filled.

    Note: API credentials issued after December 1st 2014 begin with the characters "APP" and are alpha-numeric. Earlier version of client credentials had the same format as ORCID iDs (sixteen digits). Both formats behave the same way, though our documentation primarily uses the older format in examples

Use your credentials

Now that you have your credentials, it's time to start using the ORCID Public API! See Introduction to the ORCID Public API for an overview of the Public API technologies and features, or head straight to our API Documentation for examples and reference guides.
