HI. It's few years I'm using Google Adwords to download reports. The last download was on 1 October 2015.
>From 2 October 2015 I receive the exception: AdsOAuthException: Failed to refresh access token. { "error" : "invalid_grant" } at Google.Api.Ads.Common.Lib.... I think I've lost some permission but I'm not able to understand what I have to do to do regain them. Why the OAuth2 credentials I've used till now are no longer valid? The Email I'm using right now is a fine MCC Account to create a new OAuth2 credentials? This are the data I'm using right now and that worked fine till 1 October (I've masked some data) AdWordsApiServer "https://adwords.google.com" ClientCustomerId "395-340-7542" DeveloperToken "i_GJ0-YCKy2xvB3pXXXXXX" EnableGzipCompression True MaskCredentials True OAuth2AccessToken "" OAuth2CertificatePassword Nothing OAuth2CertificatePath Nothing OAuth2ClientId "837615326351-k5c4fq9bisbvg6ap4m7mqXXXXXXXXXX.apps.googleusercontent.com" OAuth2ClientSecret "XXXXXXXXXXXXXXXXX" OAuth2Mode APPLICATION {0} OAuth2RefreshToken "1/EvQcEAWFMupf3EEseOyAwtW7izrjPygnHHXXXXXXXX" OAuth2Scope "https://www.googleapis.com/auth/adwords" RetryCount 3 Signature "AwApi-DotNet/18.17.0, Common-Dotnet/3.9.0, .NET CLR/4.0.30319.34209" Timeout 100000 UnixTimestamp 1446116265 UserAgent "Performedia Srl - PerformDB" AUTH_ENDPOINT "https://accounts.google.com/o/oauth2/auth" I'm using the Google AdWords .NET client library (used the 2015.06 and now the 2015.09 with the some results) https://github.com/googleads/googleads-dotnet-lib Thanks for the help -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
