Hi, Thanks for reaching out to Google Ads API Support.
With regards to your concern, it seems that you encounter the CREATION_NOT_SUPPORTED error. This error means that the creation of this conversion action type, which is of type “ConversionActionType.GoogleAnalytics4Custom”, isn't supported by Google Ads API. As mentioned in our documentation, the Additional Conversion Action Types are additional types of conversion actions available in reports, but may limit or prohibit creation or modification of those actions. GOOGLE_ANALYTICS_4_CUSTOM is an additional type of conversion action type. This is why you’re seeing an error message saying Creation of this conversion action type isn't supported by Google Ads API when you tried to create via Google Ads API. I hope this clarifies. Let us know if you have any further questions.
