Apigee proxy to read a json request array and update KVM with multiple key value pairs

[ApigeeLearner]

Hi,

I am trying to develop an Apigee proxy using Edge where the request to the proxy is a Json body that looks something like
{
"Proxy":
[
{"name":"Proxy1", "Param1":false, "Param2":"false"},
{"name":"Proxy2", "Param1":true, "Param2":"false"}

{"name":"Proxy3", "Param1":false, "Param2":"true"},
{"name":"Proxy4", "Param1":true, "Param2":"true"}

........

{"name":"ProxyN", "Param1":true, "Param2":"true"}
]
}

And the proxy need to pick all the values from the Json body and update a KVM with name attribute to Key and Param1 and Param2 as respective value pairs. Like below.

KEY      VALUE

Proxy1    false, false

Proxy2    true, false

Proxy3   false, true

Proxy4    true, true

......

ProxyN   true, true

I am trying with extract variables but the values in Json are dynamic meaning there can be one entry or N entries. Can someone suggest how can I achieve this?

Thanks
