Kupili Reddy enhanced the Wallet API schema for the juspay/hyperswitch repository, focusing on improving clarity and extensibility for wallet-based payments. Using Rust and OpenAPI Specification, Kupili updated the API by adding descriptive labels to WalletData and extending the WalletData enum to support new wallet types. This technical approach not only clarified the API structure but also streamlined future wallet integrations and reduced friction for downstream clients. Kupili also updated documentation to support developer onboarding and usage of the revised schema. The work demonstrated depth in API development, emphasizing maintainability and scalability, though no major bug fixes were addressed this month.
