Workflow Nodes

1. When clicking ‘Test workflow’: This is the manual trigger node to start the workflow execution.
2. Config: This set node defines the video generation parameters:
   • avatar_id: The ID of the desired AI avatar.
   • voice_id: The ID of the desired AI voice.
   • text: The script for the video's audio.
3. Create Video: This httpRequest node sends a POST request to the HeyGen API to initiate video generation. It uses the avatar_id, voice_id, and text from the Config node.
4. Wait: This wait node pauses the workflow execution for a specified amount of time (10 seconds in this case) to allow the video generation process to start.
5. Get Video Status: This httpRequest node queries the HeyGen API to retrieve the current status of the generated video, using the video_id obtained from the Create Video node.
6. is Completed: This if node checks if the video generation status is 'completed'.
7. Output: If the video is completed, this set node extracts and stores the video_url from the video status response.
