+`cookies`
+
+: _Optional_. The cookie values. Can be given unparsed as string, as dictionary, or as a list of tuples.
+
+- Example: `["PHPSESSID=12345; csrftoken=1234567"]`
+
+`headers`
+
+: _Optional_. A dictionary of submitted headers. If a header appears multiple times it, needs to be merged according to the HTTP standard for header merging. Header names are treated case-insensitively by Sentry.
+
+- Example: `[["Content-Type", "text/plain"]]`
+
 `status_code`
 
 : **Required.** The integer status code from the HTTP response associated with the event.
 
 - Example: `200`
 
+`body_size`
+
+: _Optional_. HTTP response body size in bytes.
+
+- Example: `1000`
+
+`data`
+
+: _Optional_. Response data in any format that makes sense. SDKs should discard large and binary bodies by default. Can be given as a string or structural data of any format.
+
+- Example: `"Invalid request"`
+
