* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loRest = CreateObject('Chilkat.Rest')

* IMPORTANT: Make sure to change "myaccount" to your actual Azure Storage Account name.
* IMPORTANT: Also change "mytable" to the name of your Azure table.
* We're going to POST to this URL:  https://myaccount.table.core.windows.net/mytable
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1

IF (lnSuccess <> 1) THEN
    ? "ConnectFailReason: " + STR(loRest.ConnectFailReason)
    ? loRest.LastErrorText
    RELEASE loRest
    CANCEL
ENDIF

* Provide Azure Cloud credentials for the REST call.
loAzAuth = CreateObject('Chilkat.AuthAzureStorage')
loAzAuth.AccessKey = "AZURE_ACCESS_KEY"
* The account name used here should match the 1st part of the domain passed in the call to Connect (above).
loAzAuth.Account = "myaccount"
loAzAuth.Scheme = "SharedKey"
loAzAuth.Service = "Table"

* This causes the "x-ms-version: 2019-07-07" header to be automatically added.
loAzAuth.XMsVersion = "2019-07-07"
lnSuccess = loRest.SetAuthAzureStorage(loAzAuth)

* Note: The application does not need to explicitly set the following
* headers: Content-Length, x-ms-date, Authorization.  These headers
* are automatically set by Chilkat.

* Note: The above code does not need to be repeatedly called for each REST request.
* The rest object can be setup once, and then many requests can be sent.  Chilkat will automatically
* reconnect within a FullRequest* method as needed.  It is only the very first connection that is explicitly
* made via the Connect method.

* Use this online tool to generate code from sample JSON:
* Generate Code to Create JSON

* The following JSON is sent in the request body.

* {  
*    "PartitionKey":"mypartitionkey",  
*    "RowKey":"myrowkey",  
*    "Timestamp":"2013-08-22T01:12:06.2608595Z",  
*    "Address":"Mountain View",  
*    "Age":23,  
*    "AmountDue":200.23,  
*    "CustomerCode":"c9da6455-213d-42c9-9a79-3e9149a57833",  
*    "CustomerSince":"2008-07-10T00:00:00",  
*    "IsActive":true,  
*    "NumberOfOrders":"255"
