Our JavaScript SDK comes in three flavors, @stytch/vanilla-js, @stytch/react, and @stytch/nextjs. You can install all of these packages via npm or yarn.

This guide will show you how to get set up with each SDK.

Our Next.js SDK can be used in two primary ways: with pre-built UI components and headlessly.

Select the integration method that best suits your needs.

1Install Stytch SDKs and configure your API keys

If you haven't already, create a Stytch B2B Project in your Stytch Dashboard.

Add our frontend NextJS SDK package to your Next.js application:

npm install @stytch/nextjs @stytch/vanilla-js --save

Add your Stytch project's public_token to your application as an environment variable in a .env file:

# .env
# The below values may be found in your Stytch Dashboard:

2Configure Stytch SDK settings

To allow the Stytch SDK to run on your frontend, you'll also need to:

  1. Enable frontend SDKs in Test in your Stytch Dashboard here.
  2. Add the domain your application will run on (e.g. http://localhost:3000) to the list of Domains under Authorized applications.
  3. Enable the Create organizations toggle under Enabled methods. This isn't required, but this setting will allow users to create new Organizations directly from our SDK.

3Create the UI client and wrap your application in <StytchB2BProvider>

First, initialize the Stytch UI client by invoking the createStytchB2BUIClient constructor function, passing in your Project's public token.

Next, pass the Stytch UI client to the StytchB2BProvider component at the root of your application, making it accessible to all child components.

import { StytchB2BProvider } from '@stytch/nextjs/b2b';
import { createStytchB2BUIClient } from '@stytch/nextjs/b2b/ui';

// optional object for configuring SDK cookie behavior, currently showing defaults
const stytchOptions = {
  cookieOptions: {
    opaqueTokenCookieName: "stytch_session",
    jwtCookieName: "stytch_session_jwt",
    path: "",
    availableToSubdomains: false,
    domain: "",

const stytch = createStytchB2BUIClient(

export default function MyApp({ Component, pageProps }: AppProps) {
  return (
         // Truncated

      <StytchB2BProvider stytch={stytch}>
          <div className="container">
            <Component {...pageProps} />

4Add the <StytchB2B> UI component

Create a StytchB2B component. You can configure which authentication flow and methods you'd like to offer by modifying the authFlowType and products fields respectively in your config object. Here's an example that uses our Discovery flow and utilizes our Email Magic Links product:

import { StytchB2B } from '@stytch/nextjs/b2b';
import { AuthFlowType, B2BProducts } from '@stytch/vanilla-js/b2b';

const LoginOrSignupDiscoveryForm = () => {
   const [config, setConfig] = useState<StytchB2BUIConfig | null>();

   const config = {
      products: [B2BProducts.emailMagicLinks],
      sessionOptions: { sessionDurationMinutes: 60 },
      authFlowType: AuthFlowType.Discovery,

   return <StytchB2B config={config} />;

For Email Magic Links, you must specify a redirect URL in your Project's Dashboard to authenticate the token. By default, the redirect URL is set to http://localhost:3000/authenticate.

If the <StytchB2B> component is rendered on the redirect URL used for this flow, the Email Magic Link token will automatically be authenticated. You can specify additional Redirect URLs in your Project's Dashboard, and override the default by passing in an explicit emailMagicLinksOptions.discoveryRedirectURL to your UI config.

You can read more about redirect URLs in this guide.
