Magento RestApi for C#

Question

I get an error on Initialize method.

The provided consumer secret was rejected by the server at url 'http://localhost/oauth/initiate' for consumer key 'mycosumerkey'.

I get this error when the method is called.

Here is my call:

var client = new MagentoApi()
                    .Initialize("http://localhost",
                    "myconsumerkey",
                    "myconsumersecret")
                    .AuthenticateAdmin("adminUsername", "adminPassword");

Fiddler

Header:

Answer 1

It worked fine for me. The problem is the port number.

I learned you can't include the port number of a URL for an Oauth Request. The port number gets stripped, so when the keys are compared, they don't match. Changing the port to 80 (so that it doesn't have to be included in the url) solved the problem.
