Customize Background in Conversation Setup

1

Step 1: Create Your Conversation

In this example, we will use stock replica ID rfe12d8b9597 (Nathan) and stock persona ID pdced222244b (Sales Coach).
To apply the green screen background, set the apply_greenscreen parameter to true when creating the conversation:
cURL
curl --request POST \
  --url https://tavusapi.com/v2/conversations \
  --header 'Content-Type: application/json' \
  --header 'x-api-key: <api_key>' \
  --data '{
  "persona_id": "pdced222244b",
  "replica_id": "rfe12d8b9597",
  "callback_url": "https://yourwebsite.com/webhook",
  "conversation_name": "Improve Sales Technique",
  "conversational_context": "I want to improve my sales techniques. Help me practice handling common objections from clients and closing deals more effectively.",
  "properties": {
    "apply_greenscreen": true
   }
}'
Replace <api_key> with your actual API key. You can generate one in the Developer Portal.

Step 2: Customize the Background

The above request will return the following response:
{
  "conversation_id": "ca4301628cb9",
  "conversation_name": "Improve Sales Technique",
  "conversation_url": "<conversation_link>",
  "status": "active",
  "callback_url": "https://yourwebsite.com/webhook",
  "created_at": "2025-05-13T06:42:58.291561Z"
}
The replica will appear with a green background. You can customize it using a WebGL-based on the front-end. This allows you to apply a different color or add a custom image.
