Organizations (B2B SaaS)

Prerequisite: Enable Organizations in Clerk Dashboard first.

Quick Start

1. Create an organization via dashboard or through Clerk API
2. Use OrganizationSwitcher to let users switch between orgs
3. Protect routes using orgSlug from URL and role checks

Documentation Reference

Key Patterns

1. Get Organization from Auth

Server-side access to organization:

import { auth } from '@clerk/nextjs/server'

const { orgId, orgSlug } = await auth()
console.log(`Current org: ${orgSlug}`)

2. Dynamic Routes with Org Slug

Create routes that accept org slug:

app/orgs/[slug]/page.tsx
app/orgs/[slug]/settings/page.tsx

Access the slug:

export default function DashboardPage({ params }: { params: { slug: string } }) {
  return <div>Organization: {params.slug}</div>
}

3. Check Organization Membership

Verify user has access to specific org:

import { auth } from '@clerk/nextjs/server'

export default async function ProtectedPage() {
  const { orgId, orgSlug } = await auth()

  if (!orgId) {
    return <div>Not in an organization</div>
  }

  return <div>Welcome to {orgSlug}</div>
}

4. Role-Based Access Control

Check if user has specific role:

const { has } = await auth()

if (!has({ role: 'org:admin' })) {
  return <div>Admin access required</div>
}

5. OrganizationSwitcher Component

Let users switch between organizations:

import { OrganizationSwitcher } from '@clerk/nextjs'

export default function Nav() {
  return (
    <header>
      <h1>Dashboard</h1>
      <OrganizationSwitcher />
    </header>
  )
}

Default Roles

All new members get assigned a role:

Custom roles can be created in the dashboard.

Default Permissions

Authorization Pattern

Complete example protecting a route:

import { auth } from '@clerk/nextjs/server'
import { redirect } from 'next/navigation'

export default async function AdminPage({ params }: { params: { slug: string } }) {
  const { orgSlug, has } = await auth()

  // Verify user is in the org
  if (orgSlug !== params.slug) {
    redirect('/dashboard')
  }

  // Check if admin
  if (!has({ role: 'org:admin' })) {
    redirect(`/orgs/${orgSlug}`)
  }

  return <div>Admin settings for {orgSlug}</div>
}

Common Pitfalls

Workflow

1. Setup - Enable Organizations in Clerk Dashboard
2. Create org - Users create org or admin creates via API
3. Add members - Send invitations or add directly
4. Assign roles - Default member role, promote to admin as needed
5. Build protected routes - Use auth() to check orgSlug and roles
6. Use OrganizationSwitcher - Let users switch between orgs
