* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')

* Implements the following CURL command:

* curl -X POST https://dynamodb.us-west-2.amazonaws.com/ \
*   -H "Accept-Encoding: identity" \
*   -H "Content-Type: application/x-amz-json-1.0" \
*   -H "Authorization: AWS4-HMAC-SHA256 Credential=<Credential>, SignedHeaders=<Headers>, Signature=<Signature>" \
*   -H "X-Amz-Date: <Date>" \
*   -H "X-Amz-Target: DynamoDB_20120810.ListTables" \
*   -d '{
*     "Limit": 100
* }'

* Use the following online tool to generate REST code from a CURL command
* Convert a cURL Command to REST Source Code

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.AuthAws')
loAuthAws = CreateObject('Chilkat.AuthAws')
loAuthAws.AccessKey = "AWS_ACCESS_KEY"

* Don't forget to change the region to your particular region. (Also make the same change in the call to Connect below.)
loAuthAws.Region = "us-west-2"
loAuthAws.ServiceName = "dynamodb"

* SetAuthAws causes Chilkat to automatically add the following headers: Authorization, X-Amz-Date
loRest.SetAuthAws(loAuthAws)

* URL: https://dynamodb.us-west-2.amazonaws.com/
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
* Don't forget to change the region domain (us-west-2.amazonaws.com) to your particular region.

* 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.
