ChatBotKit NextAuth SDK

The ChatBotKit SDK for NextAuth.js enables passwordless email authentication that integrates directly with ChatBotKit. This allows you to authenticate users without building separate user management infrastructure.

Two Authentication Approaches

This SDK provides two adapters for different use cases:

1. Partner Adapter (Sub-Accounts)

Use ChatBotKitPartnerAdapter when you want each user to have their own isolated ChatBotKit sub-account:

• Separate environments: Each user gets their own bots, datasets, and resources
• Complete isolation: Users cannot see or access each other's data
• Partner API integration: Requires a Partner API secret
• Best for: SaaS applications, white-label solutions, multi-tenant platforms

2. Contact Adapter (Single Account)

Use ChatBotKitContactAdapter when you want all users to be contacts within a single ChatBotKit account:

• Shared resources: All contacts can interact with the same bots and datasets
• Individual tracking: Each contact has their own conversation history and preferences
• Standard API integration: Works with a regular API secret
• Best for: Chat applications, customer support systems, community platforms

Why Use This?

Authentication is complex and risky to build yourself. This SDK lets you skip all of that.

Instead of spending weeks building and maintaining authentication infrastructure, you can:

• Launch faster: Skip building user registration, login, password reset, and account management
• Reduce security risks: No passwords to hash, no credentials to secure, no user data breaches to worry about
• Lower maintenance burden: No authentication-related bugs, no password reset support tickets, no security patches
• Eliminate infrastructure costs: No user database, no email verification system, no password reset flows
• Focus on your product: Spend time building features that make your application unique

Getting Started

Installation

Add the SDK to your project using npm:

npm install @chatbotkit/nextauth next-auth
Copy

Partner Adapter Configuration

Use this approach when each user needs their own isolated ChatBotKit environment:

import {
  ChatBotKitEmailProvider,
  ChatBotKitPartnerAdapter,
  MemoryStore,
} from '@chatbotkit/nextauth/partner'

const nextAuthConfig = {
  adapter: ChatBotKitPartnerAdapter({
    secret: process.env.CHATBOTKIT_API_SECRET,

    // Use Redis or another persistent store in production
    store: new MemoryStore(),

    // Control user lifecycle
    autoCreateUser: false,
    autoUpdateUser: true,
    autoDeleteUser: false,
  }),

  providers: [
    ChatBotKitEmailProvider({
      async sendVerificationRequest({ identifier, token }) {
        await sendEmail({
          to: identifier,
          subject: 'Sign in to your account',
          text: `Your verification code is: ${token}`,
        })
      },
    }),
  ],

  session: {
    strategy: 'jwt',
  },

  callbacks: {
    async session({ session, token }) {
      session.user = token.user
      return session
    },
    async jwt({ token, user }) {
      if (user) {
        token.user = user
      }
      return token
    },
  },

  pages: {
    signIn: '/signin',
    signOut: '/signin',
    verifyRequest: '/verify',
  },

  debug: !!process.env.DEBUG,
}

export default nextAuthConfig
Copy

Contact Adapter Configuration

Use this approach when users are contacts within a single ChatBotKit account:

import {
  ChatBotKitContactAdapter,
  ChatBotKitContactEmailProvider,
  ContactMemoryStore,
} from '@chatbotkit/nextauth/contact'

const nextAuthConfig = {
  adapter: ChatBotKitContactAdapter({
    secret: process.env.CHATBOTKIT_API_SECRET,

    // Use Redis or another persistent store in production
    store: new ContactMemoryStore(),

    // Control contact lifecycle
    autoCreateContact: true,
    autoUpdateContact: true,
    autoDeleteContact: false,
  }),

  providers: [
    ChatBotKitContactEmailProvider({
      async sendVerificationRequest({ identifier, token }) {
        await sendEmail({
          to: identifier,
          subject: 'Sign in to your account',
          text: `Your verification code is: ${token}`,
        })
      },
    }),
  ],

  session: {
    strategy: 'jwt',
  },

  callbacks: {
    async session({ session, token }) {
      session.user = token.user
      return session
    },
    async jwt({ token, user }) {
      if (user) {
        token.user = user
      }
      return token
    },
  },

  pages: {
    signIn: '/signin',
    signOut: '/signin',
    verifyRequest: '/verify',
  },

  debug: !!process.env.DEBUG,
}

export default nextAuthConfig
Copy

Create NextAuth API Route

Create pages/api/auth/[...nextauth].js:

import NextAuth from 'next-auth'

import nextAuthConfig from '../../../nextauth.config.js'

export default NextAuth(nextAuthConfig)
Copy

Environment Variables

Add your ChatBotKit API secret to .env:

CHATBOTKIT_API_SECRET=your_api_secret_here
Copy
