Unified LMS API - StackOne Hub Documentation

Legacy documentation. The Legacy Unified APIs are no longer in active development. Existing functionality remains supported, and no new features or enhancements will be added.For the current StackOne platform, connectors, and agent tooling, see docs.stackone.com.

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., files in Google Drive, SharePoint, and Dropbox all return the same schema; users in Google Workspace, Okta, and 1Password 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

Building AI agents? Use the MCP Server, an AI Toolset SDK, or the Actions API (RPC) instead. Same data, optimized for LLM tool calling.
