The text provides an overview of Unified APIs, which serve as an aggregation and abstraction layer over multiple underlying APIs, offering several advantages such as data normalization, integration lifecycle management, and infrastructure for data synchronization. Unified APIs simplify the process by aggregating data from various integrations, standardizing data models, managing authentication and authorization, and providing consistent data access through standardized API endpoints. They also handle data syncing to keep information up-to-date, emitting webhooks for real-time updates, which enhances engineering productivity and reduces infrastructure costs. The text highlights the importance of selecting a reliable and secure Unified API provider and positions Merge not just as a Unified API product but as a comprehensive integration platform for managing customer integrations.
