RE: Failed to refresh access token.

['Google Ads API Forum Advisor' via AdWords API and Google Ads API Forum]

Hi Frank,

Thank you for providing further details to your concern.

Since the issue was encountered in the code, then I would suggest to raise this 
issue instead to the author of the client library as they are more equipped 
here. Since it appears that you are using PHP client library, then I would 
suggest posting your concern here. Also, you may use this ready to use sample 
code instead for uploading conversions.

Let me know if you have further questions.

Regards,

RE: Failed to refresh access token.

[Frank Boateng]

Hi Ernie,

I have been facing conversion time issues. The documentation provides me with 
the date time format in the code image below -mm-dd hh:mm:ss+|-hh:mm
My country is south Africa as indicated with the currency code ZAR . The error 
message am getting is the string date format. I can see there is a time range 
and am finding it difficult to fix this

The older adwords has this date time format  //string conversionTime = 
DateTime.Now.ToString("MMdd HHmmss zzz");

I will be grateful for your help…

Thanks

Hi Frank,

Thank you for raising your concern.

Please note that the implementation of the Google Ads API is not the same with 
the implementation of the AdWords API. I would suggest referring to this 
document<https://developers.google.com/google-ads/api/docs/migration/services> 
to know the equivalent service of the OfflineConversionFeedService and inspect 
the fields that you need to set in uploading conversions using Google Ads API. 
Furthermore, the API service to upload conversions using Google Ads API is no 
longer asking for the conversion action name, but is now requiring the resource 
name of the conversion action instead.

To know more information on uploading conversions using Google Ads API such as 
sample implementation, then I would suggest referring to the following guides 
below:
https://developers.google.com/google-ads/api/docs/conversions/upload-clicks
https://developers.google.com/google-ads/api/docs/conversions/upload-calls

Let me know if you have further questions.

RE: Failed to refresh access token.

[Frank Boateng]

Good day,

I have Google Adwords .net application that upload offline GCLID data. I have 
to convert that to Google Ads but the parameter. In the Adwords, there was a 
conversion name in the offline conversion feed method but there is no 
conversion name in Ads. There is couple of changes that  I can’t figure out but 
I will attach screenshots and highlight the difference

If you can help me with the difference and what to use in place of the 
conversion name and what values are required for customer ID and conversion 
action ID
The customer ID I have is used as the AdWordsUser of the GoogleAdsClient


Adwords API code

Hi Frank,

Thank you for reaching out. 
Here<https://developers.google.com/identity/protocols/oauth2#expiration> are 
some common causes for the refresh token expiration. One of them is that “A 
Google Cloud Platform project with an OAuth consent screen configured for an 
external user type and a publishing status of "Testing" is issued a refresh 
token expiring in 7 days.” You could change the publishing status to production 
to avoid this issue.

Thanks and regards,

Failed to refresh access token.

[Frank Boateng]

Hello everyone,

I have an app that uses refresh token to communicate but it expires after 
some days. This is the message {Error:"invalid_grant", Description:"Token 
has been expired or revoked.", Uri:""}

I would like to have one fresh token that does not expires or enable my app 
to generate and use new refresh token every time the token expires

Thanks

I had to fill both OAuth2RefreshToken and OAuth2AccessToken in the 
AdWordsAppConfig.

Hi,
I am sorry, I have no permission to reply to the author only. The option is 
disabled and I see this tooltip: "You do not have permission to reply to 
author in this group".

Anyway, I cannot see an actual API call, this exception is thrown from the 
Google.AdWords NuGet before actually make any API call.
I think that I miss "access token" parameter 
,
 
I have "refresh token" only (which is different).  Is it necessary?

Failed to refresh access token - invalid_grant error

[Gal Talmor]

Hello,
I try to call TargetingIdeaService using the SDK (Google.AdWords NuGet, 
version 24.1.0 <https://www.nuget.org/packages/Google.AdWords/24.1.0>).
First I received a "CUSTOMER_NOT_ACTIVE" error. I created new credentials 
and generated a refresh token in console.developers.google.com 
<https://console.developers.google.com/apis/credentials?authuser=1&project=molten-team-517&supportedpurview=project>,
 
and the error changed to "Failed to refresh access token". I receive this 
error in the official tests project 
<https://developers.google.com/adwords/api/docs/samples/csharp/advanced-operations>
 I 
downloaded, so I guess that it's something in the credentials and not in 
the code.
Could you please help? Why does the token suppose to be refreshed if I just 
created it?

*The request code:*
 string accountId = "ACCOUNT_ID"; 

AdWordsUser user = 
GoogleHelper.GetUserForTargetingIdeaService(accountId);

using (var srv = 
user.GetService(AdWordsService.v201809.TargetingIdeaService) as 
TargetingIdeaService)
{
var pl = new List
{
   // ...
};
var selector = new TargetingIdeaSelector
{
requestType = RequestType.STATS,
ideaType = IdeaType.KEYWORD,
paging = Paging.Default,
searchParameters = pl.ToArray(),
requestedAttributeTypes = new AttributeType[]
{
AttributeType.SEARCH_VOLUME, 
AttributeType.KEYWORD_TEXT,
AttributeType.AVERAGE_CPC, 
AttributeType.TARGETED_MONTHLY_SEARCHES, AttributeType.COMPETITION
}
};
   
   TargetingIdeaPage page = await srv.getAsync(selector);
   // ...
  }

*The response:*
Google.Api.Ads.Common.Lib.AdsOAuthException: Failed to refresh access 
token. ---> System.AggregateException: One or more errors occurred. ---> 
Google.Apis.Auth.OAuth2.Responses.TokenResponseException: 
Error:"invalid_grant", Description:"Bad Request", Uri:""   at 
Google.Apis.Auth.OAuth2.Requests.TokenRequestExtenstions.d__0.MoveNext()
...

Thanks,
Gal

RE: I am getting error Failed to refresh Access Token .Net C#

[Google Ads API Forum Advisor Prod]

Hi Jordan,

Thank you for reaching out. The error "Failed to refresh access token" 
indicates that your refresh token is probably expired. There is likely an issue 
with your OAuth Credentials. Can you please try to generate a new set of 
credentials by following this guide and see if that fixes the issue? If you are 
still having an issue, please provide the complete detailed request and 
response logs and the email address used to generate the credentials via Reply 
privately to author so that I can further investigate the issue.

Failed to Refresh Access Token - on server

[Jordan Liberman]

I have a background/scheduled process to extract data from the AdWords API, 
and I've started receiving a message on the server that it failed to 
refresh access token.  The only info I can find on here seems to center 
around the refresh token having expired, but I use the same refresh token 
on another server with similar scheduled processes, and it is still working 
on that server.  I only have ssh access to the server, so I need the token 
access to be offline since I cannot open a web browser for OAuth 
confirmation.  This was all working correctly until I had to restart the 
server earlier today.  Please advise!

Hi Mike,

Thank you for reaching out. The error "Failed to refresh access token" 
indicates that your refresh token is probably expired. There might be an issue 
with your OAuth Credentials. Could you please try to regenerate a new set of 
credentials by following this guide and try making a call against API. If the 
issue persists, could you please provide the complete logs and the email 
address using which the credentials are generated for me to investigate this 
further? Please use Reply privately to author option while sharing the details.

I actually just found the problem 5 minutes ago and was about to update
this thread.   dependentAssembly entries had been removed from the web
app's web.config.  Once I added them back, everything ran fine.

Hello,

As your same set of credentials are working with console app, could you
please confirm that if your web app is pointing to the right property file?
Also, you can try the CURL request provided below and see if you are able
to generate the access token. If your credentials are correct, you should
be able to generate an access token for the below CURL request.

curl https://www.googleapis.com/oauth2/v4/token \
-d refresh_token=your-refresh_token \
-d client_id=your-client-id \
-d client_secret=your-client-secret \
-d grant_type=refresh_token

Re: Failed to refresh access token. See inner exception for details.

[Bob Bowles]

UPDATE: The errors are happening when a user performs a function in our 
admin web app that makes calls to the AdWords API.  We also have a console 
app that runs automated updates on a daily basis.  The console app is not 
having any problems.  Just the web app.  Both apps have always used the 
identical code and credentials.

Re: Failed to refresh access token: invalid_client

['Luis Xander Talag (AdWords API Team)' via AdWords API and Google Ads API Forum]

Hi,

Could you confirm if you are using the latest .Net client library 
<https://github.com/googleads/googleads-dotnet-lib>? Could you try to 
generate again an OAuth2 credentials by following this guide 
<https://developers.google.com/adwords/api/docs/guides/authentication#generate_oauth2_credentials>?
 
Then, try making request again. If the issue persist, could you provide the 
complete logs so I could further investigate? 

Also, I would suggest to use Google Chrome using incognito mode to make 
sure that you are using the same email address in the whole process.

Thanks and regards,
Luis

Re: Failed to refresh access token. See inner exception for details.

['Nadine Sundquist (AdWords API Team)' via AdWords API and Google Ads API Forum]

Hello KDJ,

This was sent over to me since I've worked quite a bit with more complex 
configurations. You mentioned in your last message that you're using a 
different config file with the same credentials. Can we just for a sanity 
check make sure that all those credentials are working properly?

>From the command line, try this with your refresh token and client 
information to get an access token back, where you substitute your values 
from your config file:

curl --data 
"refresh_token=&client_id=&client_secret=&grant_type=refresh_token"
 
-X POST "https://www.googleapis.com/oauth2/v3/token";

With that access token, get the debug information for me, just in case 
something does go wrong later by putting this in your browser:

https:
//www.googleapis.com/oauth2/v3/tokeninfo?access_token=

Save off that information for me in case something goes wrong in this next 
command line. 
With that access token, try this:

curl --header "Authorization: Bearer " --header 
"developerToken: 
" --header "clientCustomerId: 
" --header "clientSecret: 
" 
https://adwords.google.com/api/adwords/reportdownload/v201806 
--data "__rdquery=SELECT CampaignName, Impressions FROM 
CAMPAIGN_PERFORMANCE_REPORT DURING LAST_MONTH&__fmt=CSV"

If anything does not work, then please, in the forum, click on the drop 
down in this message and say* Reply privately to author *with this 
information. If you're only working in Windows, there are alternatives to 
curl that you can use on Windows.

If everything is working in these commands, and you're still having issues, 
then please send me the request ID of the request that failed. If you don't 
have that, then please send me the customer ID by replying privately to the 
author on the forum. I can try to look up your request on our servers to 
see if I have more information here on what exactly failed.

Best,

Sai,

I have verified that my windows service is using a separate config file.  I 
have also verified that the web application and the windows service are 
using the same credentials.  The web application and the windows service 
call the same dll which makes the call to the Adwords API.  Do you have any 
other suggestions?

['Teja Makani' via AdWords API and Google Ads API Forum]

Hello,

Thanks for the details, since the API call is working good for web 
application, you might need to check how the windows service is pulling the 
credentials and passing it to client libraries. Ideally, the same 
credentials should work provided everything else (user making the call, 
account etc.,) is same in both the applications. Could you please verify if 
there is a separate config file for windows service? Please give it a try 
and let me know if the problem still persists.

Re: Failed to refresh access token. See inner exception for details.

[rentcafedev1]

Sai Teja,

We are you VB.net library to make this call.  

As I mention in my previous email the call work fine with I'm making it 
through a web application, it just does not work when I make the call from 
a windows service.  Please note:  Both web application and the windows 
service hit the same code to make the call.  I should not need to generate 
a new refresh token since it works from my web application.

Please advise!

Re: Failed to refresh access token. See inner exception for details.

['Teja Makani' via AdWords API and Google Ads API Forum]

Hello,

Could you please confirm whether you are using AdWords .NET client library 
<https://github.com/googleads/google-ads-dotnet> for this call? If not 
could you please share the code snippet that is making the call? You could 
also cross verify that you are following the steps required to make API 
call from here 
<https://github.com/googleads/google-ads-dotnet#how-do-i-make-api-calls>.

Also, to verify that your credentials are correct, you could try the CURL 
request provided below and see if you are able to generate the access 
token. If your credentials are correct, you should be able to generate an 
access token for the below CURL request.

curl https://www.googleapis.com/oauth2/v4/token \
-d refresh_token=your-refresh_token \
-d client_id=your-client-id \
-d client_secret=your-client-secret \
-d grant_type=refresh_token

If your credentials are incorrect or still facing issue then you could try 
generating a new refresh token with the help of this guide 
<https://developers.google.com/adwords/api/docs/guides/first-api-call#get_an_oauth2_refresh_token_and_configure_your_client>
 and 
retry your request.

Hi,

I'm getting error "Failed to refresh access token. See inner exception for 
details." when I try to get campaign information.  The line of code is page 
= campaignService.get(selector) where page = "CampaignPage".  This process 
works when I use it in a web application but not when I use it in a windows 
service.  Below is some information that I hope will be helpful in figuring

service.

Re: Error: Google.Api.Ads.Common.Lib.AdsOAuthException: Failed to refresh access token

['Dannison Yao (AdWords API Team)' via AdWords API and Google Ads API Forum]

Hi,

The error *Failed to refresh access token* appears when you did not refresh 
your access token. Could you confirm if you have followed the steps in getting 
your refresh token 
<https://developers.google.com/adwords/api/docs/guides/first-api-call#get_an_oauth2_refresh_token_and_configure_your_client>?
 
If not, could you follow the guide and add the refresh token in your 
properties file? 

Let me know how this goes.

Re: Failed to refresh access token error after updating Google Adwords library version from v201708 to v201802

[Shafeena Kabir]

Hi Vincent,
Thank you very much for your help!

I was able to figure out that the property file contained duplicate keys 
for OAuth2 client ID, client secret , refresh token , developer token etc 
after API version migration. The issue got resolved after the duplicate 
keys with blank values where removed.

Thanks,
Shafeena

Re: Failed to refresh access token error after updating Google Adwords library version from v201708 to v201802

['Vincent Racaza (AdWords API Team)' via AdWords API Forum]

Hi Shafeena,

Could you confirm if after your migration, you did not change the values of 
your OAuth2 credentials in your property file? If you did not change anything 
in your property file and if the user still exists in your AdWords account, 
then it should have worked in v201802 API version.

Based on the error description "The OAUth client was not found", it seems 
that the API user is not existing (or it has been removed) in your manager 
or client account, or the client ID was deleted in the Google API Console 
Credential  page. 
So I can further investigate this, can you provide to me your complete 
error logs, clientCustomerId and the email address of your API user via *Reply 
privately to author* option?

Thanks,
Vincent

Re: Failed to refresh access token

['Peter Oliquino' via AdWords API Forum]

Hi Ran,

The error you experienced was a temporary issue and is very unusual to 
occur. Even so, catching the error is possible once implemented at your 
end, however, automatically recreating the refresh token is currently not 
possible as it is only generated manually. Additionally, could you confirm 
as well if as you said, you experience this issue once every month? If yes, 
I would recommend that you create a new forum thread and we'll continue our 
discussion from there.

Thanks and regards,
Peter

Re: Failed to refresh access token

[ran]

Hello Peter,

We recreated the RefreshToken again using the guide and it did work.
Meanwhile, this problem started reproducing about once a month.
Recreating the token works every time.

However, we didn't see in the guide a way to do the whole process of 
recreacting a refresh token automatically.
We can't seem to bypass the manual Google authentication through the 
browser (this is a web application client).

Did we miss something or there's simply no way to catch that error and 
automatically recreate the refresh token?

Thanks,
Ran.

Failed to refresh access token

[guy]

Hi,
we sometimes get this error:
Failed to refresh access token.
{
  "error" : "invalid_grant"
}

It first happened after more than a year with our token and second we 
recreated a token and it happened again after about 1.5 months.

Does anybody know why it happens? How can we prevent it?
Thanks,
Guy

Re: Failed to refresh access token, getting "Unable to connect to the remote server"

['Yin Niu' via AdWords API Forum]

Hi Pravin, 

Are you able to generate token using the OAuth 2.0 playground? If not, then 
it's probably your networking settings are not correct. 

Thanks,
Yin, AdWords API Team.

Failed to refresh access token

[AdWords API User]

We are starting to see "Failed to refresh access token" errors for our 
client accounts.  

There have been no recent changes to our application.  We have tried to 
refresh the token using OAuthTokenGenerator.exe, but the token generator 
itself returns the error message: "500. That’s an error. There was an 
error. Please try again later. That’s all we know."  A similar query has 
recently been posted on StackOverflow: 
http://stackoverflow.com/questions/36720282/since-today-google-500-error

Can you confirm whether there are any current issues with the OAuth service?

Regards,


John

Re: Failed to refresh access token: invalid_client

[Umesh Dengale]

Hello,

Could you verify that you followed all steps given in the OAuth2.0 guide 
 for 
.NET library?  Please recreate the client id and client secret and generate 
refresh token using new client id and client secret key and update the 
web.config file. Please check out the OAuth2.0 guide 
 for 
.NET library for more details. If still issue is not resolved then provide 
the steps you followed and error message.

Thanks,
Umesh, AdWords API Team.

I am using Adwords API .NET library, MCC account is linked with company's 
account, developer token has basic access. 
The OAuth client worked correctly for 14-15 days till this Monday morning

Failed to refresh access token.
{
  "error" : "invalid_client",

}
I've changed OAuth credentials, generated new refresh token, but still

+1. We're seeing a huge number of these errors - on about 2% of our calls. 
Retrying seems to help. We moved to the latest .NET release recently.

Re: Failed to refresh access token. { "error" : "invalid_client" } on perfectly good client

[Zweitze]

In my case: I use .NET 16.7.

Call stack:
 Google.Api.Ads.AdWords.v201402.FeedMappingService.get (Selector selector)
Google.Api.Ads.Common.Lib.AdsSoapClient.Invoke (String methodName, Object[] 
parameters)
 Google.Api.Ads.Common.Lib.AdsSoapClient.MakeApiCall (String methodName, 
Object[] parameters)
 Google.Api.Ads.AdWords.Lib.AdWordsSoapClient.InitForCall (String 
methodName, Object[] parameters)
 Google.Api.Ads.Common.Lib.OAuth2ProviderBase.GetAuthHeader ()
 Google.Api.Ads.Common.Lib.OAuth2ProviderBase.RefreshAccessTokenIfExpiring 
()
 Google.Api.Ads.Common.Lib.OAuth2ProviderForApplications.RefreshAccessToken 
()
 
Google.Api.Ads.Common.Lib.OAuth2ProviderForApplications.RefreshAccessTokenInOfflineMode
 
()

The call went this morning OK for (probably) a dozen or so times, and 
failed eight times. Every time the same RefreshToken, ClientId and 
ClientSecret were passed. It didn't happen on previous days / weeks / 
months.

We're experiencing the same issue, but the errors are transient. They 
happen sometimes for some accounts and are not reproducible.

It started approx. 11 hours ago.

Hello,


Did you update the client libraries recently or are they the same you've 
used before?

Same here with the PHP library:

Fatal error: Uncaught exception 'OAuth2Exception' with message '{
  "error" : "invalid_client"
}' in AdWords/Google/Api/Ads/Common/Util/SimpleOAuth2Handler.php:121

Failed to refresh access token. { "error" : "invalid_client" } on perfectly good client

[Zweitze]

Hi,

This morning a Google.Api.Ads.Common.Lib.AdsOAuthException occurred:
Failed to refresh access token.
{
"error" : "invalid_client"
}

Unfortunately the .NET library destroyed all extra information, so I don't 
have response headers, HTTP status code etc.
Anyway, the error occurred a eight times in total, between 05.25h and 
07.41h (CEST), but in that period we also did manage to retrieve access 
tokens. Before that, or after that, we had no problems.

So, what does the error mean? Obviously it doesn't mean that the supplied 
clientid and clientsecret do not exist.
And how does one handle this error? Can one retry the call?

Thanks in advance!
