update_bid_strategy

POST https://api.adspirer.ai/api/v1/tools/update_bid_strategy/execute

Change campaign bidding strategy. **Available Strategies:** - MAXIMIZE_CLICKS: Get as many clicks as possible within budget (optional cpc_bid_ceiling = max CPC cap) - MAXIMIZE_CONVERSIONS: Get as many conversions as possible - TARGET_CPA: Set a target cost per acquisition (requires target_cpa) - TARGET_ROAS: Set a target return on ad spend (requires target_roas) - TARGET_IMPRESSION_SHARE: Bid to appear for a target share of auctions at a chosen page position (requires impression_share_location + impression_share_target_percent) **Parameters:** - campaign_id: The campaign ID (REQUIRED) - strategy: one of the strategies above (REQUIRED) - target_cpa: Required if strategy is TARGET_CPA. In dollars, e.g., 25.00 for $25 CPA - target_roas: Required if strategy is TARGET_ROAS. Multiplier, e.g., 4.0 for 400% ROAS - impression_share_location: Required if strategy is TARGET_IMPRESSION_SHARE. ABSOLUTE_TOP_OF_PAGE, TOP_OF_PAGE, or ANYWHERE_ON_PAGE - impression_share_target_percent: Required if strategy is TARGET_IMPRESSION_SHARE. 1-100, e.g., 80 for 80% - cpc_bid_ceiling: Max CPC cap. Used with MAXIMIZE_CLICKS or TARGET_IMPRESSION_SHARE. In the ACCOUNT'S currency (not cents, not USD; for 8.00 send 8). Optional — omit to keep an existing ceiling; STRONGLY recommended on TARGET_IMPRESSION_SHARE. Not accepted on other strategies - customer_id: Optional (uses connected account if omitted) **IMPORTANT:** - TARGET_CPA requires conversion tracking to be set up - TARGET_ROAS requires conversion value tracking - TARGET_IMPRESSION_SHARE is for visibility goals (Search/Display); set cpc_bid_ceiling so bids don't run away chasing the target - This changes the bidding on a LIVE campaign immediately — review the values (especially the CPC ceiling and target %) before moving on - The response shows the ceiling READ BACK from Google ("Max CPC ceiling: …"); if it says "not set", the cap did not save — do not tell the user it did. `list_campaigns` / `get_campaign_structure` also report the ceiling - Changing strategy may take 1-2 weeks to stabilize performance - Confirm with user before changing **Execution time:** 2-4 seconds **Examples:** User: "I want to target $30 CPA" Agent: Uses update_bid_strategy with strategy=TARGET_CPA, target_cpa=30.00 User: "Target absolute top of page, 80% impression share, max CPC $4" Agent: Uses update_bid_strategy with strategy=TARGET_IMPRESSION_SHARE, impression_share_location=ABSOLUTE_TOP_OF_PAGE, impression_share_target_percent=80, cpc_bid_ceiling=4.00 User: "Maximize clicks but never pay more than CA$8 a click" Agent: Uses update_bid_strategy with strategy=MAXIMIZE_CLICKS, cpc_bid_ceiling=8 (account currency is CAD, so 8 means CA$8.00)
