Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential.

[Sajal Pal]

Hi,

I am trying to migrate Adwords API(sunset on 27th April, 2022) to Google Ads api. Using Asp.Net Core(5.0) and c#.

Exception:
Google.Ads.GoogleAds.V10.Errors.GoogleAdsException
  HResult=0x80131500
  Message=Status(StatusCode="Unauthenticated", Detail="Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",

I want to use "keywordPlanIdeaService"
Can anyone have any suggestions.

Hi  Nirmita,

Currently,  we are sending request like below 

                            GoogleAdsConfig config = new GoogleAdsConfig() {
                             DeveloperToken = AdwordsModel.DeveloperToken,
                             OAuth2Mode = OAuth2Flow.APPLICATION,
                             OAuth2ClientId = AdwordsModel.OAuth2ClientId,
                             OAuth2ClientSecret = AdwordsModel.OAuth2ClientSecret,
                             OAuth2RefreshToken = AdwordsModel.OAuth2RefreshToken
                            };
                            GoogleAdsClient = new GoogleAdsClient(config);

For One Account We are able to generate Access token, But for Other App we are not able to generate the Access token..

Hi Sajal, 

Thank you for the replies. I work with Nirmita and allow me to assist you here.

With regard to your concern "For One Account We are able to generate Access token, But for Other App we are not able to generate the Access token..", could you please elaborate on this concern and please provide more context of details so that we can address this. In addition to our clarification are you referring to specific authentication or Google Ads account? 

Best regards,
