Truto's Unified User Directory API maps to Slack Enterprise's admin and SCIM capabilities, exposing Users, Roles, Role Assignments, and Workspaces as unified resources. This lets you read and manage user profiles, org-level and workspace-level roles, and workspace membership across the entire Enterprise Grid organization. ### How does authentication work for Slack Enterprise integrations through Truto? Slack Enterprise Grid supports OAuth 2.0 with org-level app installation. Your end user authorizes the app once at the organization level, granting access across all workspaces in the Grid — no need for per-workspace authorization. Truto handles the OAuth flow, token management, and refresh lifecycle. ### Are there rate limits I need to worry about with Slack Enterprise APIs? Yes, Slack enforces tiered rate limits across its APIs (typically 20-100+ requests per minute depending on the method). Truto handles rate limit detection, backoff, and retry logic so your application doesn't need to manage this directly. ### Does Truto have pre-built tools for Slack Enterprise, or are they built on request? Slack Enterprise currently has no pre-built tools in Truto's catalog — they are built on request based on your specific use case. The Unified User Directory API (covering Users, Roles, Role Assignments, and Workspaces) is available today and provides a standardized interface across Slack Enterprise and other directory providers. ### Can I use Truto to manage Slack Enterprise alongside other IM or directory providers? Yes, that's the core value of Truto's unified API approach. The Unified User Directory API provides a consistent schema for Users, Roles, Role Assignments, and Workspaces. You write one integration and it works across Slack Enterprise and other supported providers, eliminating provider-specific code. ### What is the difference between integrating with standard Slack and Slack Enterprise Grid through Truto? Slack Enterprise Grid supports org-level app installation, SCIM-based user provisioning, and admin APIs for managing multiple workspaces — none of which are available on standard Slack plans. Truto's integration targets these enterprise-tier capabilities, particularly the ability to manage users, roles, and workspaces across the entire organization from a single authorization.
