Extract Query Parameter Processor is a processing element which can be used to extract a query parameter from an integration flow and set it to a scope variable.
In the following diagram there is an integration flow which takes the message in from a http ingress connector and sends out using an http egress connector. During the integration I want to extract out an query parameter which was in the original HTTP request and set it to a scope variable for later use. In the next processing element I have used a Logger to log the extracted scope variable.
Configuration for the Extract Query Parameter element is as follows. To extract a query parameter and set it to a variable, we refer query parameter using it’s name and give a scope variable name to use
