Question about offline conversions

[DEREK MATTIE]

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,
