// 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.

$oauth1->put_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..

// Setting it here is not actually necessary.

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

// 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").
