AdWords API AuthTokenException: Login failed

[SW]

Hi,

We have a process where we replicate google adwords account to
multiple client accounts(could be 20+) to copy over ads. We started
getting the login failed error recently.

We are using v200909 version with version 7 client library. Please
shed some light in resolving this or suggest a work around.

here is the error log:

Error occured in Run: com.google.api.adwords.lib.AuthTokenException:
Login failed ---> System.Net.WebException: The remote server returned
an error: (403) Forbidden.
at System.Net.HttpWebRequest.GetResponse()
at com.google.api.adwords.lib.AuthToken.GetToken()

Have you migrated to v200909 yet?
The v13 sunset is on April 22, 2010.

Hi,

This likely indicates that you are making too many requests to the
ClientLogin API in a short period of time. Are you reusing services
and/or authTokens in your application?

Best,

Reusing authentication seemed to have helped. Surprisingly,
documentation doesn't state this.

Thank you Eric

From: http://code.google.com/apis/adwords/v2009/docs/headers.html

"An authentication token is valid for about a week after you acquire it;
when it expires, use ClientLogin to retrieve a new one."

Which implies you can cache it and reuse it.
