Set extension properties

Properties control the behavior and settings of each extension, such as API keys, model parameters, and feature toggles. This guide shows you how to configure extension properties in the TEN Agent playground.

Before you start:

• Complete the Agent quickstart
• Verify the playground is running at localhost:3000

1. Open the playground at localhost:3000

2. Select a graph type such as Voice Agent or Realtime Agent

3. Click the settings button next to the graph selector to open property configuration

4. Choose an extension node from the dropdown list

5. Configure the properties for your selected extension:

   • Text values: Click the input field and enter your value
   • Boolean values: Toggle the switch
   • API keys: Enter your credentials in the secure field

6. Click Save Changes to apply your configuration

   The system displays a confirmation message when properties are successfully updated.
