Is it possible to extract value from assign message policy output?

[aayushiyadav01]

Hi,

Is there anyway through which i can extract and use the value from assign message policy output?

Like if i want to extract uuid and use it in another policy then how can i do that?

And also is there anyway through which i can only get uuid while fetching the value?

You need to use extract variable policy and using the JSON extraction you can get the UUID from the above response.

[aayushiyadav01]

<ExtractVariables name="EV-1">

<IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables> <JSONPayload>

<Variable name="uuid">

<JSONPath>$x-apigee-uuid</JSONPath> </Variable> </JSONPayload> </ExtractVariables>

I am using extract variable policy only but not able to extract uuid.
