Question

Data being sent, but not showing up on Google Ads customer list


I created a zap connecting Calendly and Google Ads. The event is triggered whenever someone books a meeting and an invitee is created. The action part of the zap was supposed to send the name, email of the client and the time the event was created to a customer list on Google Ads.

But for some reason, when I tested the zap, the testing feature says the data was sent, but I don't see the data on Google ads. This was after 12 hours had passed. What could be the problem?

Did this topic help you find an answer to your question?

Hey ​@Cel_Man, welcome to the Community! 👋

If you are using "Add Contact to Customer List" or "Add Contact to Customer List With Email" as the action in your Google Ads step, you won't see any details due to privacy purposes if you have less than 1000 users in your contact list. You can review an official response by the Google team regarding this matter here: https://groups.google.com/g/adwords-api/c/Sqs-2ztupx8/m/eDoSETbTAgAJ.

Further references of this can be found in the Google Ads API documentation here: https://developers.google.com/google-ads/api/docs/remarketing/audience-segments/customer-match/get-started#expandable-3.

Even after this threshold is reached, the data shown in the dashboard is very general, showing only a broad estimate of the number of users and their match rates.

Do you have an estimate of how many users you’ve added to your account so far?

So even if I just send email address, I still wouldn’t be able to see that in the list within Audience Manager of Google Ads?

Nice added somewhere around 2 users to the list

Hi ​@Cel_Man!

According to Google, yes. You’d need at least 1000 users added to the list to be able to see some information.
