Warnings

breaking Version 2.0.0+ changed the package name from 'ziapi_auth_client' to 'zi_api_auth_client'. Existing imports will break. ↓

fix Update imports to 'from zi_api_auth_client import AuthClient' and reinstall package.

deprecated The method 'get_token()' is deprecated in favor of 'get_access_token()' since version 1.5.0. ↓

fix Replace 'client.get_token()' with 'client.get_access_token()'.

gotcha Environment variables are not automatically loaded. You must explicitly pass credentials or set them via os.environ. ↓

fix Ensure you call load_dotenv() if using .env files, or pass credentials directly.

)
