Hi, Thank you for reaching out to the Google Ads API support team.
The UNPARSEABLE_GCLID error means that the imported gclid could not be decoded. Make sure you have not modified the click IDs. The possible reason for this is that you are uploading GCLID that does not exist. Your GCLID shouldn’t be altered/modified when importing via Google Ads API. Note that Enhanced Conversions for Leads can't be used with either WBRAID or GBRAID identifiers. If you do you will encounter the VALUE_MUST_BE_UNSET error. You can determine which of the following issues led to the error. The ClickConversion has a value set for gclid as well as at least one of gbraid or wbraid. Update the conversion to use only one click ID, and make sure you are not combining multiple clicks into the same conversion. Each click has only one click ID. The ClickConversion has a value set for either gbraid or wbraid and has a value for custom_variables. Google Ads does not support custom variables for a conversion with a gbraid or wbraid click ID. Unset the custom_variables field of the conversion. >From the provided API logs, it seems that you're currently using version v18 >of the Google Ads API. Note that 'v18' was deprecated in June 2025, and will >sunset by the end of August 2025. After this date, all v18 API requests will >fail. If you face any other issues while uploading the conversions, please share the latest complete API logs (request and response with request-id and request header) generated at your end. 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?
