# Add campaign

> Creates a campaign. `name` and the `Button` array are required; everything else is optional and configures scheduling (`has_schedule_date`, `schedule_start_date`, `schedule_start_time`), dialing behaviour (`answer_wait_time`, `after_call_dialing_auto`, `after_call_time`, `attempts`, `attempts_interval`), predictive mode (`is_predictive`, `calls_percentage`), call recording, and which contacts, agents and groups the campaign covers. Returns `201`.

Note the core API creates with `PUT`, not `POST`.
