# ContreeConfig

<a id="contree_sdk.config.ContreeConfig" />

## `class ContreeConfig`

```python theme={null}
class contree_sdk.config.ContreeConfig(auth, transport_timeout, file_upload_chunk_size, operation_import_timeout, operation_run_timeout, operation_timeout, operation_poll_secs_min, operation_poll_secs_max, operation_poll_secs_backoff_grow, operation_poll_not_found_limit, default_truncate_output_at, token_expiration_warning_threshold, images_list_batch_size)
```

Configuration for the ConTree SDK client.

The `auth` field controls authentication and the target URL. String fields
on auth objects support env var lookup: if the value matches an existing
environment variable name, the value is loaded from it.
