What is a Unified API?

A unified API provides a single, standardized interface to interact with multiple third-party providers. Instead of learning each provider’s unique API format, authentication scheme, and data model, you write code once, and StackOne handles the differences. What StackOne normalizes:
  • Data models – Consistent field names and structures across providers (e.g., employees in BambooHR, Workday, and Personio all return the same schema)
  • Authentication – OAuth, API keys, and tokens are managed per-provider; you just pass an x-account-id header
  • Pagination – Cursor-based pagination works the same regardless of whether the provider uses offsets, pages, or cursors
  • Error formats – Standardized error responses with provider-specific details when available
