+### `maxIncomingRequestBodySize`
+
+_Type: `'none' | 'small' | 'medium' | 'always'`_ (Defaults to `'medium'`)
+
+Controls the maximum size of incoming HTTP request bodies attached to events.
+
+Available options:
+- 'none': No request bodies will be attached
+- 'small': Request bodies up to 1,000 bytes will be attached
+- 'medium': Request bodies up to 10,000 bytes will be attached (default)
+- 'always': Request bodies will always be attached
+
+Note that even with the `'always'` setting, bodies exceeding 1 MB will never be attached for performance and security reasons.
+
+### `ignoreIncomingRequestBody`
+
+_Type: `(url: string, request: RequestOptions) => boolean`_
+
+Allows you to ignore the request body for incoming HTTP requests to URLs where the given callback returns `true`.
+This can be useful for long running requests where the body is not needed and we want to avoid capturing it.
+
+The callback function receives two arguments:
+
+- `url`: The full URL of the incoming request, including the protocol, host, port, path and query string. For example: `https://example.com/users?name=John`.
+- `request`: An object of type `RequestOptions` containing the incoming request's options. You can use this to filter on properties like the request method or headers.
