Create Panel
Provision a panel survey for a Panel-type study (is_panel=true), recruiting respondents that match the study’s screener questions. A BYOP study (is_panel=false) returns 400.
Set dry_run=true to preview the full cost — per-response credits and the participant reward-hold authorized on the card — without provisioning, placing the hold, or charging.
Authorizations
Authenticate with an API key (prefixed ui_sk_) or a JWT token from the dashboard.
