I'm not sure what I'm doing wrong. Part 1 works for me with no problem I take my "he-PIN-obtained-from-Step1" and plug it in on part 2 and I get a 401 error. I'm using the ActiveX version. I don't know if it has anything to do with Twitter changing it's api or not.

Here's the code and the lasterrortext with my codes removed

Dim http As New ChilkatHttp
Dim success As Long
'  Any string unlocks the component for the 1st 30 days.
success = http.UnlockComponent("Anything for 30-day trial")
If (success <> 1) Then
    Text1.Text = Text1.Text & http.LastErrorText & vbCrLf
    Exit Sub
End If

http.OAuth1 = 1 http.OAuthConsumerKey = "my-consumer-key" http.OAuthConsumerSecret = ""my-consumer-secret" http.OAuthVerifier = "the-PIN-obtained-from-Step1"

Dim req As New ChilkatHttpRequest Dim resp As ChilkatHttpResponse Set resp = http.PostUrlEncoded("https://api.twitter.com/oauth/access_token", req)

If (resp Is Nothing) Then Text1.Text = Text1.Text & http.LastErrorText & vbCrLf Exit Sub End If

If (resp.StatusCode = 200) Then 'this is where I get a 401 error

'  Get the access token and secret:

Dim oauthToken As String
oauthToken = resp.UrlEncParamValue(resp.bodyStr, "oauth_token")
Text1.Text = Text1.Text & "Access token = " _
     & oauthToken & vbCrLf

Dim oauthTokenSecret As String
oauthTokenSecret = resp.UrlEncParamValue(resp.bodyStr, "oauth_token_secret")
Text1.Text = Text1.Text & "Token secret = " _
     & oauthTokenSecret & vbCrLf

'  Your application may now perform operations on the
'  Twitter account for whatever has been authorized.
'  To do so, prior to sending the HTTP request,
'  set the OAuthToken and OAuthTokenSecret
'  properties, and also make sure to clear OAuthVerifier property:
http.oauthToken = oauthToken
http.oauthTokenSecret = oauthTokenSecret
http.OAuthVerifier = ""

'  Now that the http object has valid property values
'  for OAuthConsumerKey, OAuthConsumerSecret,
'   OAuthToken, and OAuthTokenSecret, it can send authenticated
'  Twitter requests to the user's Twitter account.

Else Text1.Text = Text1.Text & http.LastErrorText & vbCrLf End If

gives me the following ChilkatLog: PostUrlEncoded: DllDate: Dec 12 2012 UnlockPrefix: Anything for 30-day trial Username: TIMC-VISTA:timc Architecture: Little Endian; 32-bit Language: ActiveX VerboseLogging: 0 url: https://api.twitter.com/oauth/access_token RequestData: HttpVersion: 1.1 Verb: GET Path: / Charset: windows-1252 SendCharset: 0 MimeHeader: --RequestData hcCurDate: Thu, 06 Jun 2013 13:12:29 -0400 hcExpire: 11/2012 httpConnect: hostname: api.twitter.com port: 443 ssl: 1 Need to establish connection to the HTTP server...

I have the same problem. Part 1 of the example code works fine but Part 2 throws a 401 error. Any solution?

It works only when the second step also the token and the token secret is passed:

CkHttp_putOAuth1(http,True); CkHttp_putOAuthVerifier(http,''); CkHttp_putOAuthConsumerKey(http,pwidechar(fxSocial[i].OAuthConsumerKey)); CkHttp_putOAuthConsumerSecret(http,pwidechar(fxSocial[i].OAuthConsumerSecret)); CkHttp_putOAuthToken(http,pwidechar(fxSocial[i].OAuthAccessToken)); CkHttp_putOAuthTokenSecret(http,pwidechar(fxSocial[i].OAuthTokenSecret));
