# Stream Set Temporary Variable Action

With the help of the Stream Set Temporary Variable Action it is possible to set a variable in the stream and to query it at any point in the stream using the wildcard {stream.variable.?}. For example, a path that occurs repeatedly within the stream would be easier to retrieve. The variable is no longer available after the stream has ended, but it is available in a directly following stream, for example if it was set in a prestream. It will be set again the next time the same stream is executed.
