Brex Launches AI-Native Accounting API for Real-Time ERP Syncs

Brex Inc. unveiled an AI-native Accounting API on January 22, 2026, enabling continuous two-way data exchange with ERPs and real-time transaction syncing via webhooks. The API integrates with Brex’s accounting core to enforce spending policies at point of transaction, automate GL coding, and support “zero-day” closes with initial rollouts to Rillet and Campfire. Brex says the system reduces manual reconciliation and accelerates monthly closes for finance teams.
