Hello Das, That does not sound like an error that would occur due to an invalid developer token, but yes, in general you should try to make sure that you are using the appropriate credentials. I'd also recommend checking your ~/adwords.properties file to make sure you're not accidentally requesting v11 or the API or using the Sandbox URL in there.
Also, you mention that you built the source code yourself after downloading it. Are you referring to the libraries or the sample code? If you built your own copy of the libraries JAR, could you try using the pre-compiled version that comes with the client library instead? Basically, could you try following the steps in the first paragraph of "How do I start?" in the README? http://google-api-adwords-java.googlecode.com/svn/trunk/README Cheers, -Jeff Posnick, AdWords API Team On Sep 23, 8:38 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > Do I need to use proper developer token to avoid this error? > > Thanks, > > On Sep 23, 1:47 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> > wrote: > > > Hi, > > > I'm new user to Adword API, I just ran AccountServiceDemo, and got > > following error.
