Pay SDK

Pay SDK is a new SDK for accepting payments from RuStore. We strive to make interaction with RuStore products as comfortable as possible, so in the new SDK, we have taken into account your feedback received during the use of the billingClient SDK.

Pay SDK Features​

  • Convenient Integration and Quick Start

    Minimal external dependencies and simple setup through AndroidManifest.xml allow for quick SDK integration in just a few steps.

  • Flexible Payment for Any Product

    You can use either single-stage payment (immediate charge) or two-stage payment (fund reservation and purchase confirmation), regardless of the product type. The choice is always yours and depends on your business case.

  • Handling a Large Assortment of Products

    The SDK supports retrieving up to 1000 products in a single request.

  • Extended Capabilities for Working with Unauthorized Users

    The SDK allows requesting a list of products and making payments without user authorization, which helps shorten the sales cycle and increase conversion.

  • Partial Order Payment with Coupons

    The SDK supports the ability to partially pay for goods using coupons and bonuses. This helps implement effective promotional campaigns and loyalty programs.

  • Simple Purchase Processing and Accounting

    All purchases (consumable and non-consumable) are returned by a single method, which significantly simplifies transaction accounting and reduces code complexity.

  • Clear SDK Responses

    The data structure has become simpler and more informative — responses contain only the necessary information, making it easier to analyze data and integrate with your own analytics systems.

  • Transparent and Simple Error Handling

    Handling cancellations and payment errors is unified through OnFailureListener. This reduces development time and eliminates errors in implementing payment processing scenarios.
