+## Changelog

+* [#55](https://github.com/getlago/lago-python-client/pull/55) -- Error handling (`LagoApiError`)
+
+
+Example, creating wallet: 
+
+```
+try:
+    response = client.wallets().create(wallet)
+except LagoApiError as error:
+    do_something(status=error.status_code)
+```
+### Available properties:
+```
+>>> error.status_code
+422
+
+>>> error.detail
+'Unprocessable Entity'
+
+>>> error.headers
+{'X-Frame-Options': 'SAMEORIGIN', 'X-XSS-Protection': '0', 'X-Content-Type-Options': 'nosniff', 'X-Download-Options': 'noopen', 'X-Permitted-Cross-Domain-Policies': 'none', 'Referrer-Policy': 'strict-origin-when-cross-origin', 'Content-Type': 'application/json; charset=utf-8', 'Cache-Control': 'no-cache', 'X-Request-Id': '613e7542-b29e-4224-bd19-a16dd1bfa62b', 'X-Runtime': '1.024304', 'Vary': 'Origin', 'Transfer-Encoding': 'chunked'}
+
+>>> error.response
+{'status': 422, 'error': 'Unprocessable Entity', 'code': 'validation_errors', 'error_details': {'customer': ['wallet_already_exists']}}
+
+>>> error.response['error_details']['customer'][0]
+'wallet_already_exists'
+
+
+>>> error.url
+'http://localhost:3000/api/v1/wallets'
+```
