Viv,

Do you know a good example of using HttpClient ? I found this link

https://www.asp.net/web-api/overview/advanced/calling-a-web-api-from-a-net-client

but it does not recognize PostAsJsonAsync when I try to use that code.

UPDATE. Found this http://stackoverflow.com/questions/19158378/httpclient-not-supporting-postasjsonasync-method-c-sharp so I am going to add an extension as that thread suggests.

Also, I'm not clear how to set the properties I need.

The sample call which I need to use is the following:

POST /integrationapi//Attraction/Tickets/Validate HTTP/1.1
Host: hostsitehere
Content-Type: application/json
Authorization: Basic encodedstringhere
Cache-Control: no-cache
Postman-Token: encodedstringhere
 
{
  "TicketUsageRequests": [
    {
      "TicketBarcode": barcodehere",
      "TicketUsageDate": "2016-10-28T15:09:06.7021957-06:00",
      "UserID": "userNameHere"
}
  ]
}

Thanks a lot in advance.

I also found how to set Authorization. I'm not sure about Cache-Control and Postman-Token. Also, my function is going to pass number of tries. What exactly would it mean in terms of programmin.
