Hello,
Thank you for the response.
I’m currently implementing Enhanced Conversions for Leads on my website
using the Google tag (`gtag.js`). I have followed the documentation and am
setting `user_data` with a normalized (but unhashed) email address.
When a lead is submitted, the lead data is stored in our CRM, and we then
upload the normalized and hashed email addresses using the Google Ads API
(`UploadClickConversions` endpoint).
Could you please confirm if this flow is required and sufficient for
Enhanced Conversions for Leads to function correctly?
Also, on the client side, this is how we are triggering the event:
```javascript
gtag('set', 'user_data', {
email: userEmailVariable
});
gtag('event', 'form_submit', {
'send_to': 'AW-1234567890'
});
I noticed that most documentation examples use ' form_submit' as the event
name instead of 'conversion'.
Could you please clarify:
Is it required to use 'conversion' as the event name in order for Enhanced
Conversions for Leads to properly match data?
Will using an event name like 'form_submit' prevent the enhanced conversion
data from being correctly registered in Google Ads?
I’d appreciate your confirmation, as we are currently seeing the message:
"No user-provided data matches" in the Google Ads.
Thanks again for your support.
Best regards,
Muhammad Adnan
