Hi Google Ads Team

We would like to upload offline conversions via the Google Ads API, but the API returned an error message " The conversion action specified in the upload request cannot be found. Make sure it's available in this account". I am writing to enquire if u could help to solve this issue.

our customer id : 1712034044

conversion action id：7280109839

Please let me know if u need the complete API logs.

Best wishes

Hi Derek,

Thank you for reaching out to the Google Ads API support team.

The ' NO_CONVERSION_ACTION_FOUND ' error while uploading offline click conversions via Google Ads API means that the specified conversion action is either not enabled or cannot be found within the uploading of customer_id. But I could see that the conversion action: 7280109839 is enabled and is owned by the customer: 1712034044. What I have found in the past is that even though the uploading account owns the target conversion action, the GCLID may belong to a serving account that doesn't have access to the conversion action. If I could analyze the GCLIDs then I can determine whether that's the problem here.

To investigate further, please provide us with the complete API logs ( request and response with request-id and request header ) generated on your end while uploading the conversions.

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.

Additionally, checking the UI, I could see that the conversion tracking status is displayed as "Needs attention" for the conversion action: 7280109839. A “Needs attention” conversion action overview status is highlighted in yellow and indicates there are action items to address. I recommend that you kindly refer to this help center article, " Conversion Tracking: Troubleshooting conversion tracking status ," to troubleshoot your conversions based on your conversion tracking status. The offline_conversion_upload_conversion_action_summary is available starting in v17, which aggregates upload diagnostics at the conversion action level. So, I would suggest you refer to the Monitor offline data diagnostics , as it helps to find the overall health of the conversion upload processes. I have executed the conversion action level diagnostics for this conversion action and I could see that the imported data quality is 'NEEDS_ATTENTION' with few upload errors. I recommend you refer to this guide for more information about these errors and how to avoid them.

Thanks,

Google Ads API Team
