**Pre-request Script:**
```javascript
//What type of HTTP Request we're making GET|POST
var requestType = 'GET';
//When using a GET request set the urlVarString.
//Also ensuring that all values are URIencoded
if (requestType == 'GET') {
var urlVarString = [
'zone=' + encodeURIComponent('TrackingCentres')
,'page=' + encodeURIComponent('1')
];
urlVarString = urlVarString.join('&');
pm.environment.set("urlVarString", '?' +urlVarString);

if (requestType == 'POST') {

//You need to send us what IP you are sending from

//rather than setting &format in the URL Variable scope, we now define an accept header
//accept can be either 'text/json' or 'text/xml'
let accept = pm.environment.get('accept');
//we also removed the uEncoded,pEncoded & orgEncoded from the URL variable scope and it is now set as an Authorization header
//All values should be URIencoded
let Authorization = 'uencoded='+encodeURIComponent(pm.environment.get('uEncoded'))+'&pencoded='+encodeURIComponent(pm.environment.get('pEncoded'))+'&orgEncoded='+encodeURIComponent(pm.environment.get('orgEncoded'));
//Setting the first field to our request type GET|POST
let payload = [requestType];
//If the HostIP hasn't been set then we can exclude that from our Auth string. Just remember to also exclude it from your header
if (typeof HostIP != 'undefined') {

pm.environment.set("HostIP", HostIP);
}
//We now add the rest of the fields needed to our payload array
payload.push(urlPath);

payload.push(VarString);
//Create our hash using all of the fields we added to the payload array as a string, separated by '+' and encoded with our secret_key

//Update the environment variables

pm.environment.set("Authorization", Authorization);
pm.environment.set("af_hmac_signature", hash.toString());
pm.environment.set("af_iso_timestamp", isotimestamp);
