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

[rentca...@gmail.com]

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 out the problem.  I was not able to get the logging working in the windows service.

Hello,

Could you please confirm whether you are using AdWords .NET client library 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.

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 and retry your request. 

Regards,
Sai Teja, AdWords API Team.

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!

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.

Regards,

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?

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=<INSERT_REFRESH_TOKEN>&client_id=<INSERT_CLIENT_ID>&client_secret=<INSERT_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=<INSERT_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 <INSERT_ACCESS_TOKEN>" --header "developerToken: <INSERT_DEVELOPER_TOKEN>" --header "clientCustomerId: <INSERT_CLIENT_CUSTOMER_ID_WITH_DASHES>" --header "clientSecret: <INSERT_CLIENT_SECRET>" 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,
