Apr 1, 2025April 2025 performance snapshot for manikandan6695/casttree-oms-be. Delivered end-to-end improvements in payments and subscriptions, expanded metadata, and hardened deployment. Key work includes new provider data fields and payment type handling, centralized subscription lifecycle with status changes and robust failure logging, Razorpay subscription integration, and deployment/environment refinements to support reliable, scalable deployments. Core subscription creation, webhook logging, and event handling were enhanced, with billing and mandates support, plus service item type enrichment. Also completed cleanup of legacy Apple/Google IAP implementations and removal of IAP features to reduce maintenance risk. These changes collectively improve payment acceptance coverage, subscription state reliability, developer productivity, and time-to-value for new providers and payment flows.
