Worked on enhancing the Wallet API schema and documentation for the juspay/hyperswitch repository, focusing on improving clarity and extensibility for wallet-based payment integrations. Updated the OpenAPI specification by adding descriptive labels to WalletData and reorganizing the WalletData enum to support new wallet types, which streamlines future wallet integrations and simplifies onboarding for developers. The work was implemented using Rust and centered on API development and OpenAPI Specification best practices. No major bugs were addressed during this period, with efforts concentrated on feature development and documentation to reduce integration friction for downstream clients and support evolving payment requirements.
