+### Settings

+#### Partner Parameters
+
+As Adjust `partnerParameters` cannot directly be extracted from the Segment payload, as its properties are forwarded as `callbackProperties` you can specify a specific key to extract the `partnerParameters` from instead of passing it to the `callbackParameters`.
+if a value is passed behind `partnerParametersKey` it has to be a map.
