# dap env vars

To simplify configuration and improve security, the DAP CLI supports reading authentication and connection settings from environment variables. This is optional but highly recommended for automation and scripting on macOS, Linux, and Windows.

## Available Environment Variables

```sh
export DAP_API_URL='https://api-gateway.instructure.com'
export DAP_CLIENT_ID='your_canvas_data_client_id'
export DAP_CLIENT_SECRET='your_canvas_data_secret'
export DAP_CONNECTION_STRING='your_database_connection_string'
export DAP_TRACKING='your_tracking_preference'
```
