Features

Smart User Detection: Automatically handles different user scenarios without requiring you to know their status beforehand.
  • New Users: Automatically sends email invitations with 30-day expiration
  • Existing Users: Adds them directly as organization members (no email needed)
  • Current Members: Gracefully reports their existing status without errors
  • Re-invitations: Previously removed users can be seamlessly re-added
  • Mixed Batches: Process new and existing users in the same request
  • Zero Errors: No “user already exists” failures - all scenarios handled intelligently

​
Metadata

You can set organization-scoped user metadata during invitation:
  • User roles (role: "manager")
  • Department info (department: "engineering")
  • Team assignments (team: "backend")
  • Custom properties (any key-value pairs)
Organization Isolation: Metadata is scoped to your organization. If a user joins multiple organizations, each org maintains separate metadata for that user. Metadata becomes accessible to both frontend and backend after user signs up and can be updated later via the Update User Metadata endpoint.
For sensitive data that should only be server-accessible, set it after signup using Clerk webhooks.

​
Limits

  • Batch Size: 1-50 invitations per request
  • Email Validation: All email addresses must be valid
  • Rate Limiting: Subject to Clerk’s API rate limits
  • Expiration: Invitations expire after 30 days
