Learn how to get credentials for the Reader SDK before configuring the Reader SDK sample application.
Warning
The Square Reader SDK is deprecated and will be retired on December 31, 2025. The SDK is no longer receiving new releases and support for new operating systems isn't guaranteed.
The Mobile Payments SDK launched as the successor of the Reader SDK and is now in General Availability (GA). To ensure continued support and functionality, you should migrate your application from the Reader SDK to the Mobile Payments SDK before the retirement date.
Complete the following steps to request credentials and generate a Reader SDK repository password:
Open the Developer Console. You're prompted to sign in or create an account.
Create a Square application and name it Reader SDK Quickstart.
Choose the Reader SDK Quickstart application to open your Square application settings pages.
In the left pane, choose Reader SDK, and then choose Request Credentials to generate your Reader SDK repository password.
Important
Keep your Reader SDK settings page open. You need the application ID and repository password to configure the Reader SDK sample application in the next step. Use the Generate Mobile Auth Code button to authorize the sample application in Take a Cash Payment.
