Definition: API errors refer to ads that our system was not able to process due to the Ad Platforms API compatibility errors with specific campaigns, ad sets/ad groups, or ads in your ad account. These typically occur due to legacy campaigns, ad set or ad settings.
Can this be fixed by the user: No
How to fix these ads: Unfortunately, these errors are caused by the Ad Platforms API and no fix can be applied. To tag these ads you will have to apply UTMs manually. You can access all of your UTM tags via the CSV Download in the dashboard or you can download a list directly from the CSV link in the Data Connector Email Update.
