Advantages

  • No Dependency on UAT Environment: Traditional integration methods often encounter obstacles due to issues with UAT environments. Mock SDK removes this roadblock, enabling you to integrate without external dependency.
  • Streamlines Integration: Mock SDK is designed to create a smoother integration experience, ensuring a hassle-free process. This allows you to quickly offer Turbo UPI services to the users.
  • Effortless Integration for Essential Flows: Mock SDK simplifies the process of integrating Turbo for important scenarios. This enables you to expand your range of UPI services for customers without dealing with complex requirements.
  • Seamless Transition to Production: After testing your integration with Mock SDK, you can smoothly transition to the Production SDK for final testing. This ensures a seamless and secure transition from development to live production.

​
Prerequisites

  1. Contact our integrations team to get your mobile number, app, and GitHub account whitelisted to get access to the https://github.com/upi-turbo/android-turbo-sample-app - sample app repository.
    • In this repository, you will find the AAR files (libraries for Turbo) and the sample app source code to help you do the entire integration.
    • The AARs on the main branch are for the production environment, the ones on the TURBO-719 branch are for the UAT environment, and the mock-product is for the mock environment.
    These are the important files in the sample app repo:
    • app/libs: All libraries (Bank, SecureComponent, and Turbo).
    • app/build.gradle: All transitive dependencies needed to integrate Turbo SDK.
  2. Integrate with the Razorpay Android Standard Checkout SDK.
  3. Import the following frameworks:
    • Checkout SDK
    • Razorpay Turbo Wrapper Plugin SDK (maven)
    • Razorpay Turbo Mock Core SDK
    • Razorpay Turbo Mock SDK
    • Razorpay SecureComponent SDK
    • Bank SDK
  4. Add the following lines to your Android project’s gradle.properties file:
    • android.enableJetifier=true
    • android.useAndroidX=true
Watch Out!
  • minSDKversion for using Turbo UPI is currently 19 and cannot be overwritten.
  • API Key Usage for Different Environments:
  • Use the rzp_test_0wFRWIZnH65uny API key id for testing on the UAT environment.
  • Use the rzp_test_vacN5cmVqNIlhO API key id for testing on the Mock environment.
  • Use the Razorpay live keys for prod testing.
  • As a compliance requirement, you need to get approval from Google for READ_SMS permission. Refer to the Google article for more details.
