Unable to switch to Manual CPC BS when using view through conversions

[paul....@adspert.de]

Hello,

While attempting to switch a campaign from Target CPA to Manual CPC through the Adwords API this error is returned:

BiddingErrors.NOT_COMPATIBLE_WITH_VIEW_THROUGH_CONVERSION_OPTIMIZATION (campaign_set_bidding_strategy) 

Firstly, why would this be the case? It seems perfectly reasonable to make manual bids on campaigns that implement analytics trackers. Is this an arbitrary restriction or simply an (small) push to have everyone use the automation provided by Google Ads?

Secondly, turning off 'Use view through conversions' in the Dashboard allows the campaigns to be bid on manually, but doesn't appear to be to be set via API (unless I missed it). Is it at all possible?
