Hi Anthony,
Sure, hope this helps
The screenshow below is taken from AdWords UI. I would like to set enhanced CPC. along with either manual bids (1) or maximise clicks to target budget (2).
According to the API, the bidding strategy type and scheme for these 3 bid types are:
TARGET_SPEND & ENHANCED_CPC are both shared bidding strategies, so therefore to create this I first need to create a shared bidding strategy -> mutate and then get the newly created bidding ID. Upon campaign creation I set the bidding strategy ID. This works fine, however this makes a flexible bid strategy which I am trying to avoid. You can see in the screenshot below it is possible to set these values without creating a flexible bid strategy. The screenshot below is from AdWords web UI. I am also able to select enhanced CPC bidding via AdWords Editor. When I set enhanced CPC via editor it also does not create a flexible bid strategy. If AdWords editor is using the same API then surely there must be a way to set this without having explicitly create a shared budget?

AdWords Editor:

Many Thanks
