My question is similar to the one posted recently
here<https://groups.google.com/forum/#!searchin/adwords-api/AdsCommon$3A$3AErrors$3A$3AAuthError/adwords-api/1J8n4bUnyh4/5-hanTeeBVwJ>
.
I am having a omniauth based rails application that uses the
google-adwords-api gem to access the adwords api gem. Until recently, the
application was working fine but suddenly, (for no apparent reason so far)
it refused to authorize with the adwords server. I have followed various
steps given on
stackoverflow<http://stackoverflow.com/questions/9241213/how-to-refresh-token-with-google-api-client>
and
searched the internet for some help, but to no avail.
What is more baffling is that the sample rails client runs without an error
which is using the similar configuration for the api access. Here's the
error message:
Authorization error occured: Authorization failed. Server message: {
"error" : "invalid_grant"
}
Here's the code responsible for the error:
...
api = get_adwords_api()
begin
session[:token] = api.authorize(
{
:oauth2_callback => login_callback_url,
:oauth2_verification_code =>params[:code]
} )
rescue AdsCommon::Errors::AuthError => e
session[:token] = api.authorize({:oauth2_callback =>
login_callback_url})
end
...
The same error occurs for both the authorize calls.
Note that I am on ruby 2.0/rails 4 application and using the v201306
version of the api.
