Hi Google Ads API Team,
We’re seeing intermittent authentication failures when calling *KeywordPlanIdeaService.GenerateKeywordIdeas*. The issue affects *some* Google Ads accounts but not others using the same app credentials. *Endpoint* POST https://googleads.googleapis.com/v19/customers/{CUSTOMER_ID}:generateKeywordIdeas *Request body* { "keywordAndUrlSeed": { "keywords": [""], "url": "" }, "pageSize": 100 } *Observed error (from our logs)* statusCode: 503 message: "Google Ads Error: 2 UNKNOWN: Getting metadata from plugin failed with error: invalid_grant" error: "ServiceUnavailableException" *Symptoms* - Only some customer accounts fail; others succeed with the same setup. - Always using the same *developer token* and *login-customer-id* (MCC level). - Endpoint and request payload are identical across working/failing cases. - Rotating to a newly re-consented refresh token sometimes resolves the issue for a given account. -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog: https://googleadsdeveloper.blogspot.com/ =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API and Google Ads API Forum" group.
