| Name | Type | Description | Notes |
|---|---|---|---|
| cost_type | string | Campaign cost model (billing event). Defaults to `CPM`. Required when `unitCost` is set so the manual bid applies to an explicit cost model. | [optional] |
| unit_cost | float | Manual bid in WHOLE account-currency units (e.g. 2.5 = $2.50). Requires `costType`. Omit for LinkedIn's automated (max delivery) bidding. LinkedIn enforces its own per-audience min/max bid bounds. | [optional] |
| optimization_target_type | string | Campaign `optimizationTargetType` (e.g. `MAX_CLICK`, `TARGET_COST_PER_CLICK`, `MAX_IMPRESSION`). Forwarded verbatim, LinkedIn validates compatibility with the objective and `costType`. Omit for the objective-derived default: `awareness` gets `MAX_IMPRESSION`, `video_views` gets `MAX_VIDEO_VIEW`, and every other goal gets `MAX_CLICK`. `lead_generation` and `conversions` also get `MAX_CLICK`, because `MAX_LEAD` and `MAX_CONVERSION` need a lead gen form or a conversion rule that neither creation flow attaches. The default applies only to `SPONSORED_UPDATES` campaigns (every boost, and the image, video and carousel standalone ads), never to the `TEXT_AD`, `DYNAMIC` and `SPONSORED_INMAILS` campaigns the other creative formats produce. It is also skipped when `unitCost` or a non-`CPM` `costType` is set, since those select manual bidding and the bid is then yours to choose. | [optional] |
| creative_selection | string | How LinkedIn rotates creatives within the campaign. Defaults to `OPTIMIZED`. | [optional] |
| audience_expansion_enabled | bool | Enable LinkedIn audience expansion. Defaults to false. | [optional] |
| offsite_delivery_enabled | bool | Deliver on the LinkedIn Audience Network. Defaults to false. | [optional] |
| connected_television_only | bool | Restrict delivery to Connected TV inventory. | [optional] |
| carousel | \Zernio\Model\LinkedInAdsPlatformDataCarousel | [optional] | |
| document | \Zernio\Model\LinkedInAdsPlatformDataDocument | [optional] | |
| spotlight | \Zernio\Model\LinkedInAdsPlatformDataSpotlight | [optional] | |
| follower | \Zernio\Model\LinkedInAdsPlatformDataFollower | [optional] | |
| jobs | \Zernio\Model\LinkedInAdsPlatformDataJobs | [optional] | |
| text_ad | \Zernio\Model\LinkedInAdsPlatformDataTextAd | [optional] | |
| conversation | \Zernio\Model\LinkedInAdsPlatformDataConversation | [optional] | |
| event | \Zernio\Model\LinkedInAdsPlatformDataEvent | [optional] | |
| thought_leader | \Zernio\Model\LinkedInAdsPlatformDataThoughtLeader | [optional] | |
| bid_strategy | \Zernio\Model\BidStrategy | [optional] | |
| bid_amount | float | Whole currency units (USD: 5 = $5.00). Required when bidStrategy is LOWEST_COST_WITH_BID_CAP or COST_CAP. May also be sent alone, WITHOUT bidStrategy, to set the cap on an ad set joining a COST_CAP / LOWEST_COST_WITH_BID_CAP campaign (the strategy is inherited from the campaign). On POST /v1/ads/create that shape requires existingCampaignId and is a 400 otherwise; on POST /v1/ads/boost it is promoted to LOWEST_COST_WITH_BID_CAP. | [optional] |
| roas_average_floor | float | Decimal ROAS multiplier (2.0 = 2.0x). Required when bidStrategy is LOWEST_COST_WITH_MIN_ROAS; sending it without bidStrategy is a 400. | [optional] |
