In October 2025, RevenueCat/docs delivered a focused OpenAPI enhancement to record store-level transaction IDs for non-subscription objects, enabling richer transaction detail and cross-store reconciliation. The change adds a new field store_transaction_id to the non-subscription objects in the OpenAPI spec, implemented in commit f4ca3f34bcb6c3b70bb34ae30729d1c660b20577 (#1167). This work improves data fidelity, analytics, and developer experience by providing stable identifiers across stores and simplifying reconciliation workflows. No major bugs were reported in this repository this month; minor documentation and validation tasks were completed as needed. Technologies demonstrated include OpenAPI/JSON Schema evolution, API specification design, and documentation tooling. Business impact: more accurate revenue analytics, faster cross-store reconciliation, and clearer API contracts for downstream integrations.
