Convex Workos

Convex + WorkOS AuthKit

Provider-specific patterns for integrating WorkOS AuthKit with Convex.

Required Configuration

1. auth.config.ts

// convex/auth.config.ts
const clientId = process.env.WORKOS_CLIENT_ID;

export default {
  providers: [
    {
      type: 'customJwt',
      issuer: 'https://api.workos.com/',
      algorithm: 'RS256',
      applicationID: clientId,
      jwks: `https://api.workos.com/sso/jwks/${clientId}`
    },
    {
      type: 'customJwt',
      issuer: `https://api.workos.com/user_management/${clientId}`,
      algorithm: 'RS256',
      jwks: `https://api.workos.com/sso/jwks/${clientId}`
    }
  ]
};

Note: WorkOS requires TWO provider entries for different JWT issuers.

2. Environment Variables

# .env.local (Vite/React)
VITE_WORKOS_CLIENT_ID=client_01...
VITE_WORKOS_REDIRECT_URI=http://localhost:5173/callback

# .env.local (Next.js)
WORKOS_CLIENT_ID=client_01...
WORKOS_API_KEY=sk_test_...
WORKOS_COOKIE_PASSWORD=your_32_char_minimum_password_here
NEXT_PUBLIC_WORKOS_REDIRECT_URI=http://localhost:3000/callback

# Convex Dashboard Environment Variables
WORKOS_CLIENT_ID=client_01...

Client Setup

React (Vite)

// src/main.tsx
import { AuthKitProvider, useAuth } from "@workos-inc/authkit-react";
import { ConvexProviderWithAuthKit } from "@convex-dev/workos";
import { ConvexReactClient } from "convex/react";

const convex = new ConvexReactClient(import.meta.env.VITE_CONVEX_URL);

ReactDOM.createRoot(document.getElementById("root")!).render(
  
    
      
    
  
);

Install: npm install @workos-inc/authkit-react @convex-dev/workos

Next.js App Router

// components/ConvexClientProvider.tsx
'use client';

import { ReactNode, useCallback, useRef } from 'react';
import { ConvexReactClient, ConvexProviderWithAuth } from 'convex/react';
import { AuthKitProvider, useAuth, useAccessToken } from '@workos-inc/authkit-nextjs/components';

const convex = new ConvexReactClient(process.env.NEXT_PUBLIC_CONVEX_URL!);

export function ConvexClientProvider({ children }: { children: ReactNode }) {
  return (
    
      
        {children}
      
    
  );
}

function useAuthFromAuthKit() {
  const { user, loading: isLoading } = useAuth();
  const { accessToken, loading: tokenLoading, error: tokenError } = useAccessToken();

  const loading = (isLoading ?? false) || (tokenLoading ?? false);
  const authenticated = !!user && !!accessToken && !loading;

  const stableAccessToken = useRef(null);
  if (accessToken && !tokenError) {
    stableAccessToken.current = accessToken;
  }

  const fetchAccessToken = useCallback(async () => {
    if (stableAccessToken.current && !tokenError) {
      return stableAccessToken.current;
    }
    return null;
  }, [tokenError]);

  return {
    isLoading: loading,
    isAuthenticated: authenticated,
    fetchAccessToken,
  };
}

Install: npm install @workos-inc/authkit-nextjs @convex-dev/workos

Next.js Middleware

// middleware.ts
import { authkitMiddleware } from '@workos-inc/authkit-nextjs';

export default authkitMiddleware({
  middlewareAuth: {
    enabled: true,
    unauthenticatedPaths: ['/', '/sign-in', '/sign-up']
  }
});

export const config = {
  matcher: ['/((?!.*\\..*|_next).*)', '/', '/(api|trpc)(.*)']
};

Next.js Auth Routes

// app/callback/route.ts
import { handleAuth } from '@workos-inc/authkit-nextjs';
export const GET = handleAuth();

// app/sign-in/route.ts
import { redirect } from 'next/navigation';
import { getSignInUrl } from '@workos-inc/authkit-nextjs';
export async function GET() {
  return redirect(await getSignInUrl());
}

// app/sign-up/route.ts
import { redirect } from 'next/navigation';
import { getSignUpUrl } from '@workos-inc/authkit-nextjs';
export async function GET() {
  return redirect(await getSignUpUrl());
}

CORS Configuration (React/Vite only)

For React apps, configure CORS in WorkOS Dashboard:

1. Authentication > Sessions > Cross-Origin Resource Sharing (CORS)
2. Click Manage
3. Add your dev domain: http://localhost:5173
4. Add your prod domain when deploying

UI Components

import { useAuth } from "@workos-inc/authkit-react"; // or authkit-nextjs/components
import { Authenticated, Unauthenticated } from "convex/react";

function App() {
  const { user, signIn, signOut } = useAuth();

  return (
    <>
      
         signOut()}>Sign out
        
      
      
         signIn()}>Sign in
      
    
  );
}

Auto-Provisioning (Development)

Convex can auto-create WorkOS environments for development:

1. Run template: npm create convex@latest -- -t react-vite-authkit
2. Follow prompts to link Convex team with WorkOS
3. Dev deployments auto-provision WorkOS environments

Configured automatically:

• Redirect URI
• CORS origin
• Local environment variables in .env.local

Limitations:

• Only works for dev deployments
• Production must be manually configured

Dev vs Prod Configuration

| Environment | API Key | Redirect URI | | ----------- | ------------- | ---------------------------------- | | Development | sk_test_... | http://localhost:3000/callback | | Production | sk_live_... | https://your-domain.com/callback |

Set different WORKOSCLIENTID in Convex Dashboard for dev vs prod deployments.

WorkOS-Specific Troubleshooting

| Issue | Cause | Fix | | ------------------------- | ------------------ | ------------------------------------------------------------------------- | | CORS error | Domain not added | Add domain in WorkOS Dashboard > Sessions > CORS | | Token validation fails | Wrong issuer | Check BOTH providers in auth.config.ts | | Missing aud claim | JWT config | Check WorkOS JWT configuration | | "Platform not authorized" | Workspace unlinked | Run npx convex integration workos disconnect-team then provision-team |

"Platform not authorized" Error

npx convex integration workos disconnect-team
npx convex integration workos provision-team

Note: Use a different email if creating new WorkOS workspace.

DO ✅

• Include BOTH provider entries in auth.config.ts (different issuers)
• Configure CORS for React/Vite apps
• Use useConvexAuth() not WorkOS's useAuth() for auth state
• Set WORKOSCLIENTID in Convex Dashboard
• Use 32+ char WORKOSCOOKIEPASSWORD for Next.js

DON'T ❌

• Forget the second provider entry (user_management issuer)
• Skip CORS configuration for browser-based apps
• Use WorkOS auth hooks to gate Convex queries
• Hardcode the client ID (use env var)
• Use same WorkOS env for dev and prod
