Below issue was posted by me on https://github.com/XiaoFaye/WooCommerce.NET/issues/414 but since this may not be related at all to WooCommerce.Net but on a lowerlevel to Apache/Word/WooCommerc itself I am posting the same question here
I am really stuck with the famous error:
WebException: {"code":"woocommerce_rest_authentication_error","message":"Invalid signature - provided signature does not match.","data":{"status":401}}
FYI:
I am running WAMP on both machines to run Apache and host Wordpress on port 80
The error ONLY occurs when trying to call the Rest api on the remote server. Connecting to the local rest api, the Rest Api/WooCommerceNet is working like a charm :-)
On the remote server I have defined WP_SITEURL as 'http://[ip address]/webshop/ and WP_HOME as 'http://[ip address]/webshopin wp-config.php
Calling the api url (http://[ip address]/webshop/wp-json/wc/v3/) from my local browser works OK. I get the normal JSON response
Is there anybody that can point me into the direction of a solution?
Your help will be much appreciated!
In my case, the problem was in my url adress. The URL Adress had two // begin wp-json
Url Before the solution: http://localhost:8080/wordpress//wp-json/wc/v3/
URL Now, and works ok: http://localhost:8080/wordpress/wp-json/wc/v3/
I use with this sentence.
RestAPI rest = new RestAPI(cUrlApi, Funciones.CK, Funciones.CS,false);
WCObject wc = new WCObject(rest);
var lstWooCategorias = await wc.Category.GetAll();
I hope my answer helps you.
