Configure the Order-Ahead Sample Application

Applies to: Orders API | OAuth API

Learn how to configure the sample application and test your credentials.

Download the order-ahead sample application from GitHub and complete the following steps to configure the sample application for your environment.

1. Download the order-ahead sample application from GitHub.

2. In the root directory of the sample, create a copy of the .env.example file and name the new file .env.

3. In the .env file, replace the placeholder SQUARE_SANDBOX_ACCESS_TOKEN and SQUARE_SANDBOX_APPLICATION_ID values with the Sandbox credentials that you copied in Step 1: Get Developer Credentials.

   The following shows an example of new values:

   # Sandbox Credentials
   SQUARE_ACCESS_TOKEN=GmbHQbFdRGhiYCNp8sxVzdcfwhXPEi6KU-qbZohsWQeBC55iGHq5TB6Msexample
   SQUARE_APPLICATION_ID=sandbox-sq0idb-ueuyW79WprkFzwXexample
   ...

   You can optionally set your production credentials; however, you work in the Square Sandbox for the rest of this tutorial.

   Important

   You should use your own credentials only for testing the sample application. If you plan to make a version of this sample application available for your own purposes, use the OAuth API to securely obtain and manage access to Square accounts.

When you've finished setting up your credentials, you can test the order-ahead sample application to confirm that you've authorized your application.

To test the order-ahead sample application:

1. Run the following command in the root directory of the order-ahead sample application:

   npm test

2. Open localhost:3000 in your browser. If your sample application is set, you should see a gray screen with your business location name at the top.
