Deduplication of conversion data (OCI)

[Ash Tiwari]

To whom this may concern:

We have had to make some corrections to conversion records in our database, and need to re-upload conversions data for the past 90 days. We will use our existing Google Ads API integration for this.

The primary change is that we did not have hashed PII for the past 90 days, and now we do, and we want to make sure to send Google the enhanced conversions. Will such an upload be successful? Will it overwrite the previous conversions and replace those with enhanced conversions? Or will both records exist side by side?

Thanks

Hi Ash,

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

Regarding your interest in sending enhanced conversions using the Google Ads API, please find the answers to your questions below:

1. Will the upload be successful ?

Yes, the upload should be successful, provided that the PII such as email, phone number, and name/address, is properly hashed before sending. Additionally, ensure that the other parameters, like 'conversion_action' and 'conversion_date_time' etc are correctly implemented.

2. Will it overwrite previous conversions?

No, enhanced conversions do not overwrite the previously uploaded conversions but rather supplement them with more accurate data. 

3. Do both records exist side by side?

Both records (original and enhanced) will exist side by side, providing a richer picture of conversion performance.  

Also, note that the Google Ads API allows for uploading two types of enhanced conversions:

• Enhanced conversions for leads
• Enhanced conversions for web 

To help you further, could you specify which type of enhanced conversion you are planning to implement?  

Thanks,
 

Google Ads API Team
