' Demonstrates how to do OAuth1 authentication for a Wordpress site using Woo Commerce.

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

' Prepare an OAuth 1.0 object for use with the Chilkat REST API.
Dim oauth1 As Chilkat.OAuth1
Set oauth1 = Chilkat.NewOAuth1
oauth1.ConsumerKey = "WOO_COMMERCE_CONSUMER_KEY"
oauth1.ConsumerSecret = "WOO_COMMERCE_CONSUMER_SECRET"

' The signature method can be HMAC-SHA1 or HMAC-SHA256
oauth1.SignatureMethod = "HMAC-SHA256"

' The OauthUrl property will need to be updated each time a request is sent.
' The domain here must match the domain passed to the Connect method (below).
' The domain must be exact.  For example, "www.your-wordpress-site.com" vs. "your-wordpress-site.com".
' One might work while the other does not..
oauth1.OauthUrl = "http://your-wordpress-site.com/wc-api/v3/orders"

' The OAuthMethod property will be set automatically when the REST request is sent.
' Setting it here is not actually necessary.
oauth1.OauthMethod = "GET"

' Generate an initial nonce so that Chilkat knows the desired size of the nonce.

success = oauth1.GenNonce(32)

Dim rest As Chilkat.Rest
Set rest = Chilkat.NewRest

' Tell the REST object to use the OAuth1 object for authentication.
' Also, indicate that the OAuth authentication parameters should be query parameters
' and not located within the Authorization header.

bUseQueryParams = True
success = rest.SetAuthOAuth1(oauth1,bUseQueryParams)

' Make the initial connection (without sending a request yet) to the WooCommerce endpoint at your Wordpress blog.

bTls = False

port = 80

bAutoReconnect = True
success = rest.Connect("your-wordpress-site.com",port,bTls,bAutoReconnect)
If (success <> True) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

' Send a GET request to list orders.

' When the request is sent, the OAuth1 object's Timestamp and Nonce properties are automatically
' regenerated.  Also, the OAuth1 object's OauthMethod property is automatically set to the HTTP method
' used for the request (in this case it is "GET").

responseJson = rest.FullRequestNoBody("GET","/wc-api/v3/orders")
If (rest.LastMethodSuccess <> True) Then
    Debug.Print rest.LastErrorText
    Exit Sub
End If

' When successful, the response status code will equal 200.
