Advertiser ID.

Fixed campaign budget or initial campaign budget. When `budget_auto_adjust_strategy=UNSET`, this is the fixed campaign budget. When `budget_auto_adjust_strategy=AUTO_BUDGET_INCREASE`, this is the initial campaign budget; to retrieve the current campaign budget, check the returned `current_budget`.

Campaign budget strategy for automatic daily campaign budget. Valid only when all of the following are true: `budget_optimize_on=true`, `budget_mode=BUDGET_MODE_DYNAMIC_DAILY_BUDGET`, and `app_promotion_type` is not `MINIS`. When set to `AUTO_BUDGET_INCREASE`, Goal-based budget increase is enabled; the specified `budget` becomes the initial daily budget, and the daily budget can automatically increase by 20%, up to 10 times per day, when budget utilization reaches 90% or more. The daily budget resets to the original daily budget each day. `UNSET` disables Goal-based budget increase. This feature is allowlist-only; contact your TikTok representative for access.
