Hello,
please add ‘optimization_goal’ to the facebook ads fields. It’s a further breakdown of campaign objective and integral to my campaign analysis. It’s a common API field. I’ll attach a screen shot and link below! Thanks.

optimization_goal appears to have been added, but incorrectly. It’s showing data for adset_destination type https://windsor.ai/data-field/facebook/#adset_destination_type
Please fix.

https://windsor.ai/data-field/facebook/#adsset_optimization_goal does that work as expected?
