Hi, Thank you for contacting the Google Ads API support team.
After reviewing your concern, I understand that you are encountering the "INTERNAL_ERROR" when trying to use KeywordPlanIdeaService.GenerateKeywordHistoricalMetrics method. Please note that the INTERNAL_ERROR occurs when something unexpected happens while processing the request. The common cause could be the API isn't functioning correctly. However, this is transient in nature and the API request will work again when retrying it after 30 seconds or some time. You may also retry any requests that failed with this error, using an exponential backoff schedule for the retries. Here is a code example demonstrating how to implement an exponential back off strategy. If the issue still persists, then provide us with the below information, so that we can investigate this issue further. Date of this issue started How much time did you wait before retry of a request Updated complete API request and response logs with request-id and request header generated at your end without redacting any information. If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag. You can send the details via Reply privately to the author option, or direct private reply to this email. Thanks, Google Ads API Team Feedback How was our support today?
