Configure Yahoo! Japan Data Solution Connectivity for NodeJS

Connectivity to Yahoo! Japan Data Solution from NodeJS is made possible through CData Connect Cloud. To work with Yahoo! Japan Data Solution data from NodeJS, we start by creating and configuring a Yahoo! Japan Data Solution connection.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
