I am trying to extract variables of request payload using extract variable policy. below is the code I am using.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> EV-Payload true $.MillId $.Quantity request apigee

But the policy is not extracting values. Can anyone identify the error I made.

Thanks,

Hira

ExtractVariables with the JSONPayload optionwill work, only if the content-type is application/json .

If you have a text/plain content-type, then EV will ignore it and will not extract. Could that possibly be what you are seeing?

When I try your policy with a sample proxy, it works if the content-type is correct.

$ curl -i $apigee/ev-json-payload-test/t1 -H content-type:application/json -d '{ "MillId": "abcd", "Quantity" : "1500" }'
