UAT Sandbox

The UAT Sandbox allows you to simulate end to end payment flows and test your integration thoroughly. It uses templates that map APIs to predefined sample responses, enabling you to simulate various scenarios such as payment Success, Failure, and Pending without real transactions.

Benefits of using the UAT Sandbox

Even if the PhonePe UAT server is unavailable, the UAT Sandbox ensures a smooth testing experience. You can continue validating payment flows without disruptions.
Simulate various payment outcomes such as success, failure, and pending states. This helps ensure your integration handles all real-world scenarios reliably.
Thoroughly test the entire payment lifecycle from initiation to response. This ensures a stable and seamless experience when you move to production.

Android Test App

Download and install the PhonePe Test app to verify the flows in UAT.

Android – Download from here [Package Name: com.phonepe.simulator]
For Android, in the SDK, set the environment value as SANDBOX to test payments.
Android SDK Version: 5.2.0.

Test App Setup

Click on “Settings” and configure the “VPA for Collect” like @ybl that can be used for testing the UPI Collect Flow.
