Face Swap (HeyGen API)
Swap a face from a source image into a target video using GPU-accelerated AI processing. The source image provides the face to swap in, and the target video receives the new face.
Authentication
All requests require the X-Api-Key header. Set the HEYGEN_API_KEY environment variable.
bash
curl -X POST "https://api.heygen.com/v1/workflows/executions" \
-H "X-Api-Key: $HEYGEN_API_KEY" \
-H "Content-Type: application/json" \
-d '{"workflow_type": "FaceswapNode", "input": {"source_image_url": "https://example.com/face.jpg", "target_video_url": "https://example.com/video.mp4"}}'Default Workflow
- Call

GET /v1/workflows/executions/{id}every 10 seconds until status iscompleted - Use the returned

}Usage Examples
Basic Face Swap
bash
curl -X POST "https://api.heygen.com/v1/workflows/executions" \
-H "X-Api-Key: $HEYGEN_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"workflow_type": "FaceswapNode",
"input": {
"source_image_url": "https://example.com/headshot.jpg",
"target_video_url": "https://example.com/presentation.mp4"
}
}'Chain with Avatar Video
Generate an avatar video first, then swap in a custom face:
python
import time
# Step 1: Generate avatar video
avatar_execution_id = requests.post(
"https://api.heygen.com/v1/workflows/executions",
headers={"X-Api-Key": os.environ["HEYGEN_API_KEY"], "Content-Type": "application/json"},
json={
"workflow_type": "AvatarInferenceNode",
"input": {
"avatar": {"avatar_id": "Angela-inblackskirt-20220820"},
"audio_list": [{"audio_url": "https://example.com/speech.mp3"}],
},
},
).json()["data"]["execution_id"]
# Step 2: Wait for avatar video to complete
while True:
status = requests.get(
f"https://api.heygen.com/v1/workflows/executions/{avatar_execution_id}",
headers={"X-Api-Key": os.environ["HEYGEN_API_KEY"]},
).json()["data"]
if status["status"] == "completed":
avatar_video_url = status["output"]["video"]["video_url"]
break
time.sleep(10)
# Step 3: Swap in a custom face
faceswap_execution_id = faceswap(
source_image_url="https://example.com/custom-face.jpg",
target_video_url=avatar_video_url,
)Best Practices
- Use a clear, front-facing face photo — the source image should show a single face with good lighting
- Face swap is GPU-intensive — expect 1-3 minutes processing time, poll every 10 seconds
- Source image quality matters — higher resolution face photos produce better results
- One face per source image — the source should contain exactly one face to swap in
- Works with any video — the target video can be an avatar video, a recording, or any video with visible faces
- Chain with other workflows — generate an avatar video first, then swap in a custom face for personalization
