Note: Creating an OAuth application requires a Smartsheet developer account.

To register an app and obtain the OAuth client credentials, the client Id and client secret:

1. Log into your Smartsheet developer account.
2. Click Account > Developer Tools > Create New App.
3. Enter a name, description, and other information to be displayed to users when they log in to grant permissions to your app.
4. Set other parameters, depending on the type of application you are creating:
   • For desktop applications, set the Redirect URL to http://localhost:33333 or a different port number of your choice.
   • For Web applications, set the Redirect URL to the page where the user should return after they authorize your application.
