​
Step 6: Connect to Your Vercel Project

1

Return to Vercel

Go back to your Vercel dashboard where you initiated the Chatbase installation.
2

Click Connect Project

  1. In the Chatbase integration settings, click Connect Project
  2. A dialog will appear showing all your Vercel projects
  3. Select the project(s) where you want to add the Chatbase chatbot
You can connect the same chatbot to multiple projects if needed.
3

Confirm Connection

Click Connect to finalize the connection. Vercel will automatically inject the environment variables into your selected project(s).
Your environment variables are now configured and ready to use!

​
Step 7: Redeploy Your Project

1

Trigger a New Deployment

For the environment variables to take effect, you need to redeploy your project:
  1. Go to your project in the Vercel dashboard
  2. Click on the Deployments tab
  3. Click the three-dot menu (⋯) on your latest deployment
  4. Select Redeploy
Environment variables are injected at build time, not runtime. This is why a redeployment is necessary.

​
Step 8: Verify Installation

1

Visit Your Deployed Project

Once the deployment is complete:
  1. Click the Visit button in your Vercel dashboard
  2. Or navigate directly to your project’s URL
Your Chatbase chat widget should now appear on your website, typically in the bottom-right corner.
2

Test the Chat Widget

Verify that your chatbot is working correctly:
  1. Look for the chat bubble - Should be visible in the corner of your page
  2. Click to open - The chat interface should expand
  3. Send a test message - Try asking a question related to your training data
  4. Verify response - The AI should respond based on the sources you configured
If the chatbot responds appropriately to your test questions, your integration is successful!

​
Managing Your Integration

​
Updating Your Chatbot

Changes made in your Chatbase dashboard apply instantly without requiring redeployment:
  • Appearance customization - Colors, position, styling
  • Training data updates - Add or remove sources
  • Response behavior - Adjust personality and model
  • Actions and integrations - Enable or disable features
Only environment variable changes require redeployment. All chatbot configuration changes are live immediately.

​
Advanced Features

​
Multiple Projects

You can connect the same Chatbase chatbot to multiple Vercel projects:
  1. Go to your Vercel dashboard
  2. Navigate to Integrations → Chatbase
  3. Click Manage on your Chatbase integration
  4. Click Add Project to connect additional projects
This is useful if you have multiple frontends (web app, marketing site, documentation) that should use the same chatbot.

​
Different Chatbots for Different Environments

To use different chatbots for production, preview, and development environments:
  1. Create separate chatbots in Chatbase for each environment
  2. In Vercel, manually override environment variables:
    • Go to Settings → Environment Variables
    • Set different NEXT_PUBLIC_CHATBOT_ID values for Production, Preview, and Development
This allows you to:
  • Test changes without affecting production conversations
  • Maintain separate training data per environment
  • Monitor environment-specific analytics separately

​
Managing Your Subscription Plan

To change your Chatbase subscription:
  1. Go to your Vercel dashboard
  2. Navigate to Integrations → Chatbase → Settings
  3. Click Change Plan
  4. Select your desired plan option

​
Upgrading Your Plan

Choose a higher-tier plan and complete the invoice payment.
Plan upgrades take effect immediately once the invoice is paid. You’ll have instant access to all the features and increased limits of your new plan.
What happens when you upgrade:
  • Your new plan features activate right away
  • Increased message limits are available immediately
  • Any prorated charges are calculated automatically
  • Your billing cycle continues with the new plan pricing

​
Downgrading Your Plan

Choose a lower-tier plan to switch to.
Plan downgrades take effect at the end of your current billing period. This ensures you don’t lose access to features you’ve already paid for.
What happens when you downgrade:
  • You continue to enjoy your current plan features until period end
  • The new plan activates automatically when your billing cycle renews
  • You’ll receive a confirmation email with the effective date
Downgrading at period end means you get full value for what you’ve paid. Use the remaining time to adjust to the new plan’s limits or export any data if needed.

​
Canceling Your Subscription

Select the Free plan and confirm your cancellation.
Subscription cancellations also take effect at the end of your current billing period. Your chatbot will continue working until then, ensuring you receive full value for your payment.
What happens when you cancel:
  • Your chatbot remains active until the end of your billing period
  • You retain access to all current plan features until period end
  • No future charges will be processed
  • You can resubscribe at any time if you change your mind
  • After cancellation takes effect, your plan reverts to the Free tier
You can undo a cancellation before the period end by selecting a paid plan again from the same settings page.

​
Uninstalling the Integration

If you need to remove the Chatbase integration:
  1. Go to your Vercel dashboard
  2. Navigate to Integrations → Chatbase
  3. Click Manage → Remove Integration
  4. Confirm removal
Removing the integration will immediately stop the chatbot from appearing on your Vercel deployments. Make sure to redeploy after removing environment variables.
