Linear SCIM guide

Zoom supports native SCIM 2.0 provisioning, but only on Business plans and above ($18.33/user/month minimum). While this covers most enterprise use cases, Zoom's SCIM implementation has specific requirements that can create friction: your email domain must be pre-associated with your Zoom account, users need existing Zoom accounts with SSO login types for proper provisioning, and recent OAuth2 migration requirements mean existing Bearer auth integrations need reconfiguration. For smaller teams on Pro plans ($14.99/user/month), upgrading to Business just for SCIM means a 23% price increase purely for provisioning automation. For a 50-person team, that's $1,020/year in additional licensing costs. The domain association requirement can also delay initial deployments, especially for organizations with complex domain structures.

ChatGPT Enterprise supports native SCIM 2.0 for automated user provisioning, but OpenAI restricts this capability to their highest-tier Enterprise plan with custom pricing (estimated ~$60/seat for 70+ users). The Business plan includes SSO but deliberately excludes SCIM, forcing IT teams into manual user management despite paying $25-30/user/month. This creates a significant pricing cliff: teams must jump from Business to Enterprise—often doubling their spend—just to automate basic user lifecycle operations. This gap between SSO and SCIM creates operational friction for IT teams managing AI tool adoption. While employees can authenticate through your identity provider on the Business plan, you still need to manually provision accounts, manage group memberships, and handle offboarding. For organizations rapidly scaling ChatGPT usage across departments, this manual overhead becomes a bottleneck. The 40-minute sync delay on Azure Entra ID compounds these challenges, making real-time access management impossible even on Enterprise.

Slack supports SCIM provisioning (the protocol that lets your identity provider automatically create, update, and remove user accounts). But Slack restricts full SCIM functionality to Enterprise Grid—its top-tier plan that costs ~$230/user/year and requires custom pricing negotiations. Teams on Business+ ($180/user/year) get SSO but no automated provisioning, creating a manual management burden that defeats the purpose of centralized identity management. The pricing jump from Business+ to Enterprise Grid represents a 28% increase plus the complexity of Grid's multi-workspace architecture. For a 200-person team, that's an additional $10,000/year just to unlock automated user lifecycle management. Once you upgrade to Enterprise Grid, Slack's policy is permanent—no downgrades allowed, ever—making this a high-stakes decision that locks you into their most expensive tier indefinitely.
