Developer Dashboard

Square provides the Developer Dashboard to manage your applications, permissions, and authorizations, the Seller Dashboard to track seller activity and create seller resources, and the Sandbox Seller Dashboard to simulate the seller experience when testing APIs.

When you sign up for a Square account, Square provides the Developer Dashboard and Seller Dashboard, which you can access using the Account menu:

A drop-down menu that shows the Developer Dashboard and Seller Dashboard options.

  • Developer Dashboard - Use the Developer Dashboard to create and manage your applications, access the Sandbox Seller Dashboard, configure webhooks for real-time notifications, and perform other development tasks.
  • Sandbox Seller Dashboard - You can use the Sandbox Seller Dashboard to simulate the seller experience when testing APIs in the Square Sandbox. You can access it through the Developer Dashboard.
  • Seller Dashboard - The Seller Dashboard provides sellers with tools to manage daily business operations. A seller can control just about everything needed to ensure that the business is running smoothly.

Developer Dashboard

The Developer Dashboard lets you manage all aspects of your applications in one place. These tasks include:

  • Creating an application and viewing the application ID and application secret.
  • Subscribing to webhook events and designating the notification URL where you receive webhook event notifications.
  • Setting up OAuth permissions so you can manage resources on behalf of a seller.
  • Reviewing logs for API calls and webhook events.

Explore the Developer Dashboard

  1. Sign in to the Developer Dashboard.
  2. On the Applications page, choose an application that you created.
  3. At the top of the page, toggle Sandbox or Production to set your environment. For information about the Sandbox, see Square Sandbox.
  4. In the left pane, choose the following pages and review the application's configuration settings:

  • Credentials - Provides the credentials used to authenticate requests. Credentials are provided for use in production and Sandbox testing. The API version is the default version for your application.


    The access token on the Credentials page has permissions to update all Square account data. You should therefore not share this access token with other people.

  • OAuth - Provides the access tokens needed to test your code in the Sandbox environment. For production applications, use the OAuth workflow to obtain tokens at runtime.

  • Locations - Displays all locations created for your Square account. Square creates the initial location based on the information you provided during signup. Several Square APIs require your location ID. If you're signed in to Square, API Explorer prompts you to select one of your locations when creating an API request.

In addition, each application maintains information on other pages, such as webhooks (for push notifications) and client payments configurations.

Square applications

A Square application lets you register your application with Square so that your code can connect to Square and make API calls. The application provides the necessary development credentials needed to build with the Square API.

In addition to managing credentials, you can manage webhook subscriptions, API versions, Apple Pay configurations, and more. The API version that you choose for the application is the default Square API version. If your application makes an API call without an HTTP version header, Square applies this default version to the request.

You might only need one application to address your business needs, but you can create additional applications in the Developer Dashboard if needed. For example, you're using the Square Developer platform to:

  • Create web and mobile client payment solution and a backend application to support both clients. In this case, you might create an application for each of the three platforms.
  • Create solutions for different scenarios, such as managing orders or managing a Square catalog.

App Marketplace

You can use the Developer Dashboard to publish your application in the App Marketplace and manage your reviews. For information on building and publishing an app on the App Marketplace, see App Marketplace.

Sandbox Seller Dashboard

You can use the Sandbox Seller Dashboard to simulate the seller experience when testing APIs in the Square Sandbox. You can access it through the Developer Dashboard.

When you make API calls using the Sandbox test account, you can verify those transactions in the Sandbox Seller Dashboard. These transactions don't affect your production data.

Open the Developer Dashboard and review the Sandbox Seller Dashboard, as shown in the following example:

The Sandbox test accounts section shows the Default Test Account.

  1. Review the Sandbox default test account:

    1. Choose (ellipsis) and view the details of the Sandbox default test account.


      If you created your Square account in a supported region (where Square supports processing payments, see supported countries), Square creates this Sandbox default test account in the same country as your Square account. Otherwise, Square creates the account in the US because the Sandbox test account can only be created in regions where Square can process payments. Also, any simulated payments made in a Sandbox account follows the banking and payment rules for that country. For example, if you create a Sandbox test account for France, when you use the OAuth API for test payments, Square processes the payments according to the payment regulations of France.

    2. Choose Done to close the Account Details window.

  2. Choose Open next to Default Test Account.

  3. Review and close the Sandbox Seller Dashboard.
