+The type of the body that will be sent with the request. Possible values are `json`, and `string`.
+
+##### `body`
+The body that will be sent with the request. It can be a string or a map. Example:

+body-type: json
+body:
+  key1: value1
+  key2: value2
+  multiple-items:
+    - item1
+    - item2
+```
+
+```yaml
+body-type: string
+body: |
+  key1=value1&key2=value2
+```
+
 ##### `frameless`
 When set to `true`, removes the border and padding around the widget.
