This example demonstrates a bare-bones Node.js implementation of the OAuth flow for Square APIs. It serves a link that directs merchants to the OAuth Permissions form and handles the result of the authorization, which is sent to your application's Redirect URL (specified on the application dashboard).

This application requires the Node.js Square SDK and Express, which you install via npm. Open your terminal in this directory and type:

npm install

1. Open the Developer Dashboard.

2. Choose Open on the card for an application.

3. At the top of the page, set the dashboard mode to the environment that you want to work with by choosing Sandbox or Production.

4. Choose OAuth in the left navigation pane. The OAuth page is shown.

5. In the Redirect URL box, enter the URL for the callback you will implement to complete the OAuth flow: http://localhost:8000/callback

   You can use HTTP for localhost but an actual web server implementation must use HTTPS.

6. In the Application ID box, copy the application ID.

7. In the Application Secret box, choose Show, and then copy the application secret.

8. Click Save.

9. In your project directory, create a copy of the .env.example file and name it .env

10. In the newly created .env file, replace the your-environment with either sandbox or production

11. Replace the your-application-id and your-application-secret placeholders with the Sandbox or Production application ID and application secret, respectively.

    Note that OAuth Sandbox credentials begin with a sandbox prefix and that the base URL for calling Sandbox endpoints is https://connect.squareupsandbox.com. When you implement for production, you need production credentials and use https://connect.squareup.com as the base URL.

    WARNING: Never check your credentials/access_token into your version control system. We've added .env to the .gitignore file to help prevent uploading confidential information.

1. Open the Developer Dashboard.

2. For testing in sandbox mode, in the Sandbox Test Accounts section, find one test acount and choose Open. For production mode, open the seller dashboard at https://squareup.com/dashboard/

3. Start the Node server, if it is not running:

   npm start
   

4. Open http://localhost:8000/request_token to start.
