Looking at the code example for driving mobile app downloads
the code uses the bidding strategy configuration of CONVERSION_OPTIMIZER. Yet in the UI, I use TARGET_CPA or MAX_CPA which seems to be a sub category of conversion optimizer. What is the difference between CONVERSION_OPTIMIZER and TARGET_CPA in code for a bidding strategy?
Reading the documentation for the UI
It seems I should use TARGET_CPA since the campaigns I'm creating won't have any previous data to be used for CONVERSION_OPTIMIZER?
