+{
+  "packageName":{
+    "opt":"packageName",
+    "description":"python package name (convention: snake_case).",
+    "type":"string",
+    "default":"swagger_client"
+  },
+  "packageVersion":{
+    "opt":"packageVersion",
+    "description":"python package version.",
+    "type":"string",
+    "default":"1.0.0"
+  },
+  "sortParamsByRequiredFlag":{
+    "opt":"sortParamsByRequiredFlag",
+    "description":"Sort method arguments to place required parameters before optional parameters.",
+    "type":"boolean",
+    "default":"true"
+  }
+}
+```
+To set package name to `pet_store`, the HTTP body of the request is as follows:
+```
+{
+  "options": {
+    "packageName": "pet_store"
+  },
+  "swaggerUrl": "http://petstore.swagger.io/v2/swagger.json"
+}

+```
+curl -H "Content-type: application/json" -X POST -d '{"options": {"packageName": "pet_store"},"swaggerUrl": "http://petstore.swagger.io/v2/swagger.json"}' https://generator.swagger.io/api/gen/clients/python
