Always getting error "requestId is required" when doing POST on quickbooks payment API Apps Script - rest

Question

Im creating a script that will process a credit transaction and I always getting this response:
{
"errors": [
{
"code": "PMT-4002",
"type": "invalid_request",
"message": "requestId is required.",
"detail": "requestId",
"infoLink": "https://developer.intuit.com/v2/docs?redirectID=PayErrors"
}
]
}
Im trying to figure out where to put the "request-id" parameter on the request body. Here is my code:
function QBOcreatecharge(){
var token = "TOKEN"
var service = getQuickbooksService();
if (service.hasAccess()) {
var url = 'https://sandbox.api.intuit.com/quickbooks/v4/payments/charges'
var Details =
{
"amount": "80.00",
"currency": "USD",
"capture": "false",
"token": token
}
var params = {
headers: {
Authorization: 'Bearer ' + service.getAccessToken()
},
contentType: 'application/json',
method: 'POST',
payload: JSON.stringify(Details),
muteHttpExceptions:true
}
var response = UrlFetchApp.fetch(url, params);
var value = JSON.parse(response.getContentText())
Logger.log(value)
}
else{
var authorizationUrl = service.getAuthorizationUrl();
Logger.log('Open the following URL and re-run the script: %s', authorizationUrl);
}
}
How do I add the requestId parameter? I tried to insert it on the link, on the header and nothing work. Im using UrlFetch on Google Apps Script. Any help will be appreciated. Thanks!

The Request-Id is a header you need to send. e.g.:
headers: {
Authorization: 'Bearer ' + service.getAccessToken(),
'Request-Id': your unique value here
},
Intuit documents it here:
