Is it possible to fetch a value from a response and use it in the following request? for example: ``` https://localhost:3000 Content-Type: application/json; -- -- # create item # response is { "itemId": "asdfasdf"} POST /item { "data": "data"} var1 = res.itemId -- # update item PUT /item/:var1 { "data": "blah"} ``` If yes, can you please tell me how? Thank you
