-## Options
+## Configuring OpenAPI Generator for Compatibility
+
+Default options for https://openapi-generator.tech/docs/generators/spring/ have changes over time and different versions. Here is a sample configuration that works with this version of ZenWave360 SDK.
+
+```xml

+            </configuration>
+        </execution>
+    </executions>
+</plugin>
+```
+
+Also, make sure you set `required: true` for `requestBody` in your OpenAPI definition for post, put, patch...
+
+```yaml
+requestBody:
+  required: true # this is important
+  content:
+    application/json:
+      schema:
+        $ref: "#/components/schemas/Customer"
+```
