Now that you have a Square account and application, you can make your first API call using API Explorer.
In API Explorer, create a payment using the Square Sandbox environment. Calls in the Sandbox use the
connect.squareupsandbox.com domain as the base URL.
After you create an account (as described in Create an Account and Application), the Developer Dashboard opens and displays the following blue banner:
- Choose the Open API Explorer link on the banner. This opens API Explorer and populates all the fields that are required to send a
CreatePaymentrequest to the Payments API.
If you don't see the banner, use this API Explorer link to open the prepopulated view directly.
- Choose Run Request.
- Review the Request and Response panes:
- The Request pane shows the request that was sent. You can change the default cURL view to see the request in another programming language.
- The Response pane shows the response from Square. If the payment is successful, Square returns a
Paymentobject with the
statusfield set to
source_id in the request is a Sandbox payment token that represents a credit card. In production, payment tokens are generated by the Web Payments SDK or In-App Payments SDK. For more information, see Take Payments.
