`billing_event_type`	string or SelectableOption	Yes	-	Bid / billing event type. Must match the parent campaign’s objective: ‘impression’ for an impressions campaign, ‘click’ for both clicks and conversions campaigns (for a conversions/oCPC campaign the bid amount is the target CPA).
`strategy`	string or SelectableOption	No	-	Bidding strategy: ‘fixed_bid’ (the default if omitted) bids the bid_amount; ‘maximize_clicks’ / ‘maximize_conversions’ bid automatically, making bid_amount optional.
`bid_amount`	number	No	-	Maximum bid in account currency, not micros. This value is converted to micros automatically before sending to the API. Required unless strategy is ‘maximize_clicks’ or ‘maximize_conversions’. For a conversions (oCPC) campaign this is the target CPA per conversion.
`custom_audience_bid_multipliers`	array of OpenAIAdsAudienceBidMultiplier	No	-	Audience bid adjustments as objects or JSON. Omit to preserve existing adjustments; pass [] to clear, including when switching to Maximize strategies.
