# Upgrading to v3

> Changes in the Maxim SDK

## Maxim SDK Initialization changes

* `apiKey` is now `api_key` in `Config`
* `baseUrl` is now `base_url` in `Config`

```python apiKey is now api_key in Config theme={null}
from maxim import Maxim,Config

maxim = Maxim(Config(api_key="maxim-api-key"))
```

## Import changes

We have pulled out most commonly used imports at the relevant places.

1. `from maxim.logger import Logger, LoggerConfig` instead of `from maxim.logger.logger import Logger, LoggerConfig`
2. `from maxim import Maxim, Config` instead of `from maxim.maxim import Maxim, Config`
3. `from maxim.logger import Trace, TraceConfig` instead of `from maxim.logger.trace import Trace, TraceConfig`

<Note>
  Old imports will still work.
