Meta Ads conversion data is missing or partial

Hi there, 

I’ve set up Meta Ads integration and it has been working for some time. In Meta Ads, I’m now looking to create a new campaign with a performance goal rather than an install goal. When trying to select the event to set as the goal, both the standard events ‘Start trial’ and ‘Subscribe’ are disabled with an error 

Your app can't use Aggregated Event Measurement because conversion data is missing or partial. Usually, the easiest solution is to set up the Facebook SDK for iOS.

Do you think I’m missing any steps in the Meta Ads integration set up? I’ve added details about my setup and review I’ve just completed. Appreciate your help with this. 

 

Here is my Meta Ads set up 

In app 

  • `collectDeviceIdentifiers()` call 
  • `setFBAnonymousId()` call
  • Both of these set up after Purchases SDK is configured
  • When ATT prompt is authorized, set `isAdvertiserIDCollectionEnabled` and call `collectDeviceIdentifiers`.

Next, I have integrated with Conversions API. 

Is the Datasource ID (mentioned in Conversions API set up page in RC) and the Dataset ID in Event Manager > Datasets, the same thing?

Hi ​@prasanna,

Thanks for reaching out. I took a look at your projects Meta Ads integration and everything seems to be configured correctly. The appropriate identifiers are being populated for customers, and events are being successfully delivered to Meta. I believe in this case Meta just hasn’t received events of sufficient matching quality.

I’d recommend going inside Events Manager in Meta, opening your dataset and reviewing AEM eligibility. Usually there are some troubleshooting steps listed there which you can follow. I’d also recommend contacting Meta support as they might be able to provide some context on the situation that we might be missing from our end.

Hope this helps, let me know if you have any other questions, I’m happy to help.

Best,

Hussain

Thanks for that information, ​@hussain. 

I've reached out to Meta. Can I validate something as I wait for the Meta staff to come back to me?

Is what I'm trying to do achievable and has been done in the past? one app which has revenue cat SDK and meta SDK integrated and running an install goal campaign and I'm trying to set up a events goal campaign. 

The meta agent I was working with today seemed to suggest that's not possible but I wanted to validate this information as I've heard conflicting information from meta folks on this.

Hi ​@prasanna. This should be possible, but whether Meta will let you optimize for these events (given the AEM eligibility of these events and whether they’re satisfied with the matching quality/source consistency) is up to logic on their end. I assume the Meta agent was talking more about data quality / sourcing requirements rather than if it’s possible at all. Do you have any additional information from Meta?
