Example webhook handler using FastAPI:

```python
from dotenv import load_dotenv
from fastapi import FastAPI, Request
from fastapi.responses import JSONResponse
from elevenlabs.client import ElevenLabs
from elevenlabs.errors import BadRequestError
import os

load_dotenv()

app = FastAPI()
elevenlabs = ElevenLabs(
    api_key=os.getenv("ELEVENLABS_API_KEY"),
)

WEBHOOK_SECRET = os.getenv("WEBHOOK_SECRET")

@app.post("/webhook")
async def receive_message(request: Request):
    payload = await request.body()
    signature = request.headers.get("elevenlabs-signature")

    try:
        event = elevenlabs.webhooks.construct_event(
            rawBody=payload.decode("utf-8"),
            sig_header=signature,
            secret=WEBHOOK_SECRET,
        )
    except BadRequestError as e:
        return JSONResponse(content={"error": "Invalid signature"}, status_code=401)

    # construct_event returns a dict (parsed JSON), not an object with attributes
    if event.get("type") == "post_call_transcription":
        print(f"Received transcription: {event.get('data')}")

    return {"status": "received"}
```
