A/B Test Results Aggregator

## Setup Instructions
1. **Configure Credentials**: Add your API tokens for Optimizely and VWO in the HTTP Request nodes.
2. **Slack Setup**: Connect your Slack account and specify the channel name (e.g., `marketing-reports`).
3. **Schedule**: Adjust the Schedule Trigger if you want reports more or less frequently than every 24 hours.
4. **Data Mapping**: The 'Aggregate Results' code node assumes a generic JSON structure. You may need to adjust the property names (e.g., `active_count`) based on the actual API response from your tools.
