Hi @saveuser12345,

For you to use the extracted value of id in the body of the request, you would need to set the value of id to an environment or global variable as given below and then access it using the double brackets in the request:

key = JSON.parse(pm.environment.get("Key_value"));
pm.environment.set("id", key.objects[0].id);
or
pm.globals.set("id", key.objects[0].id);
