// 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.
CkoOAuth1 *oauth1 = [[CkoOAuth1 alloc] init];

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.
BOOL success = [oauth1 GenNonce: [NSNumber numberWithInt: 32]];

CkoRest *rest = [[CkoRest alloc] init];

// 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.
BOOL bUseQueryParams = YES;
success = [rest SetAuthOAuth1: oauth1 useQueryParams: bUseQueryParams];

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

if (success != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

// 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").
NSString *responseJson = [rest FullRequestNoBody: @"GET" uriPath: @"/wc-api/v3/orders"];
