Obtain an access token via the TikTok for Business OAuth 2.0 flow and note your advertiser_id.
POST to https://business-api.tiktok.com/open_api/v1.3/campaign/create/ with advertiser_id, campaign_name, objective_type (e.g. TRAFFIC, CONVERSIONS, APP_PROMOTION), and budget_mode (BUDGET_MODE_DAY or BUDGET_MODE_TOTAL).
Capture the campaign_id from the response and create an ad group by POSTing to /adgroup/create/ with campaign_id, placement_type, targeting fields, budget, schedule_type, and optimization_goal.
Create an ad creative via /ad/create/ supplying the adgroup_id, creative material (image or video material_id), ad text, and call-to-action.
Set operation_status to ENABLE on each entity only when ready to serve; create entities as DISABLE during setup.
Verify the campaign hierarchy with GET /campaign/get/ passing the campaign_id.
Known gotchas
TikTok's API versioning is in the URL path (v1.3 as of mid-2025); always check the latest stable version in the developer portal as endpoints evolve.
The Access-Token header must accompany every request — unlike some platforms, TikTok does not support query-parameter token passing on most endpoints.
Budget minimums vary by market and objective; requests with budgets below the minimum are rejected with a specific budget error code.
