```

## Apple Podcasts Connect

### Analytics Export
```python
import requests

# Apple Podcasts Connect API (requires JWT auth)
# See: https://developer.apple.com/documentation/appstoreconnectapi

headers = {"Authorization": f"Bearer {jwt_token}"}
response = requests.get(
    "https://api.appstoreconnect.apple.com/v1/analyticsReportRequests",
    headers=headers
)
```

## Building a Dashboard

### Python Analytics Aggregator
```python
from dataclasses import dataclass
from datetime import date

@dataclass
class PodcastMetrics:
    date: date
    downloads: int
    unique_listeners: int
    avg_completion: float
    top_countries: dict

async def aggregate_metrics(show_id: str, start: date, end: date):
    # Fetch from multiple sources
    transistor = await fetch_transistor(show_id, start, end)
    op3 = await fetch_op3(show_id, start, end)

    return PodcastMetrics(
        date=end,
        downloads=transistor.downloads + op3.downloads,
        unique_listeners=transistor.unique_listeners,
        avg_completion=transistor.avg_completion,
        top_countries=transistor.countries
    )
```
