April 2026 monthly summary for lago-openapi: Focused on Wallet Alerts documentation and schema accuracy to reduce integration friction and improve developer onboarding. Key changes include adding missing wallet_ongoing_balance_amount and wallet_credits_ongoing_balance types, and splitting the subscription and wallet alert schemas to ensure each only includes values that belong to it.

This work enhances API clarity, improves client SDK generation, and supports faster feature adoption across Wallet Alerts integrations.

March 2026: Implemented end-to-end wallet management and alerts capabilities across lago-go-client, lago-api, and lago-openapi; introduced wallet alerts in GraphQL; improved performance for fees data paths; added a unique constraint to enforce data integrity; and enhanced developer-facing documentation for customer wallets and alerts.

February 2026: Delivered a major Wallet API restructuring under the customer namespace in getlago/lago-api. Introduced new endpoints for wallet operations and wallet metadata under /customers/:customer_external_id/wallets/:code, while preserving existing wallet endpoints to ensure zero-downtime migration. This alignment with the wallet alerts API improves usability, resource grouping, and onboarding for customer-specific wallet management. The work enhances API consistency across wallet-related resources and establishes a foundation for future wallet governance features, driving easier integrations for customers and internal teams.

This enables customers to tailor invoice dating (e.g., last day of billing period) to their business rules, addressing customer feedback and reducing invoicing errors. The work aligns with Notion specs and roadmaps and integrates alongside the existing invoice_grace_period settings.
