OAuth applications let your custom tools and integrations authenticate with the ION API. ION supports two app types: web and desktop apps using the PKCE flow, and IoT or limited-input devices using the Device Authorization Grant.

​
Register an app

  1. In ION, go to Settings > Organization > OAuth Apps.
  2. Click Register App.
  3. Enter an Application Name.
  4. Select the application type:
    • Web / Desktop App (PKCE): For web or desktop applications using the Authorization Code + PKCE flow.
    • Device / Wearable: For IoT devices or limited-input devices using the Device Authorization Grant.
  5. Click Register.
Copy the Client ID from the app’s entry for use in your application.

​
Add redirect URIs (web / desktop apps only)

After registering a web or desktop app, add the URIs your application uses:
  1. In the app’s entry, click Add Callback URL and enter your callback URL (for example, https://your-app.com/callback).
  2. Optional: Add any of the following:
    • Click Add Origin to add an allowed CORS origin.
    • Click Add Logout URL to add a post-logout redirect URL.
An app’s URLs are grouped under Callback URLs, Allowed Origins (CORS), and Logout URLs. To remove one, click the X next to the URL you want to remove.
An app’s name and type are fixed after registration. To change them, delete the app and register a new one.

​
Delete an app

  1. In ION, go to Settings > Organization > OAuth Apps.
  2. In the app’s entry, click the delete icon.
  3. Confirm the deletion.
Deleting an OAuth app revokes access for all applications using that client ID. This cannot be undone.
