Hi Denis, It looks like you are using the upload offline conversions sample. The sample specifies that custom variable constants are optional:
// Optional: Specify the conversion custom variable ID and value you want to // associate with the click conversion upload. private const CONVERSION_CUSTOM_VARIABLE_ID = null; private const CONVERSION_CUSTOM_VARIABLE_VALUE = null; You should be able to just leave these as null.
