Hi,
Thank you for raising this concern to the Google Ads API Forum.
Upon checking the Google Ads UI, it says that
"To let Google Ads automatically set bids to maximize your clicks, leave this field blank.". This behaviour is also applicable in the Google Ads API when I tried the simple API transaction without setting value to the target_spend.cpc_bid_ceiling_micros. Let me know if you have further questions.
Best regrads,
