How to pass the POST method response to the GET method header

[Community Alums]

Hi Experts,

I have requirement where I need to pass the POST method response to HTTP header value in GET method,
Below is the First Screenshot of POST method response, where the highlighted token which I need to pass into the GET method header value in 2nd screenshot.
Each time token value in the response will changes, so how can I fetch that value and pass it to the GET method header.
The Authentication type is : No authentication 

Thanks in advance,
Chaithanya

You may use a script include to call first API and parse the token from its Response.

then call second api by setting header as below.

var token = from First API

var r = new sn_ws.RESTMessageV2('REST Message', 'HTTP Method');

r.setRequestHeader('X-Tableu-Auth', token);

You can set header for 2nd API as below

Key: X-Tableu'-Auth

value: ${token}

Hi @Swapna Abburi 
The response from the POST method is in XML format, from that how can I fetch the required value?
