POST Json Request using VBA ?

[JumboCactuar]

Hi,
i have used the VBA-JSON before and understand how to use it for GET requests, but for POST i am unsure of the best route to take.

e.g:

POST /orders/markasshipped HTTP/1.1
Host: ssapi.shipstation.com
Authorization: __YOUR_AUTH_HERE__
Content-Type: application/json

{
  "orderId": 93348442,
  "carrierCode": "usps",
  "shipDate": "2014-04-01",
  "trackingNumber": "913492493294329421",
  "notifyCustomer": true,
  "notifySalesChannel": true
}

How would i build that in VBA? I dont see a simple way due to the way double quotes are handled.

Is it possible to have a TXT file with this as a template, and edit that TXT file before POST


Thanks in advance
