You can try your agent directly in WhatsApp using the Kapso sandbox before connecting it to a real WhatsApp Business account.

​
Using the Kapso Sandbox

​
1. Create a WhatsApp sandbox session

To test your agent in WhatsApp, you need to create a sandbox session. This will give you access to interact with your agent via the Kapso Sandbox number.

Create Sandbox Session
kapso create sandbox-session

You’ll be prompted to enter your phone number. This is the number where you’ll receive the WhatsApp messages from your agent:

​
2. Activate your sandbox session

After creating the sandbox session, you’ll need to activate it:

  1. Open WhatsApp on your phone
  2. Either:
    • Click the activation link provided (e.g., https://wa.me/56926403035?text=THVIOX), which will open WhatsApp with the message pre-filled
    • OR manually add the sandbox number to your contacts and send the activation code (e.g., THVIOX) to it

Once activated, you’ll receive a confirmation message, and your sandbox session will be ready to use.

​
3. Test your agent

With your sandbox session activated, you can now:

  1. Deploy your agent if you haven’t already:
Deploy Agent
kapso deploy
  1. Start chatting with the agent through the WhatsApp sandbox number

The agent will respond through WhatsApp, allowing you to test the conversational experience exactly as your end users would see it.
