Open on GitHub

What faceswap does

The skill configures workflow calls to HeyGen via the /v1/workflows/executions endpoint. It submits a FaceswapNode task containing a source face picture and a target video file. The API answers with an execution ID for tracking.

Remote GPU processing takes between 1 and 3 minutes. The assistant polls the execution status every 10 seconds until the job completes. Without setting HEYGEN_API_KEY in your environment, every request fails immediately.

What it helps with

  • swap a face in an existing video with a new portrait
  • automate HeyGen face swap workflow executions
  • generate personalized marketing videos from a single photo

Example prompts for the agent

  • Swap the face in target-video.mp4 with the person from face-photo.jpg using HeyGen
  • Run a FaceswapNode workflow with my source portrait and wait for the result
  • Submit a face swap execution to the HeyGen API and poll until completed
