Jun 1, 2025June 2025 focused on advancing tokenized payments and API clarity in the KodyPay client SDK. Delivered end-to-end card token management capabilities, enabling creation, retrieval, listing, deletion, and payments via tokens, with a new delete-token endpoint and support for optional shopper references during payment initiation. Improved resiliency and clarity in the data model by adding a default UNSPECIFIED value for RecurringProcessingModel in ecom.proto and clarifying token_id documentation. These changes reduce merchant integration effort, decrease risk of undefined states, and improve developer experience. The work is backed by targeted commits and aligns with security and scalability goals.
