Get Discovery Prefill

The ServiceTitan lists an org picks its install scope from.

Names, not ids: Pilot's warranty pipeline scopes by name (DISCOVERY_PROFILES), so a picker keyed by id would not match what the config expects.

The org's own contact details, as every portal registration carries them.

Read off one active business unit — the fullest, since divisions disagree on address and phone. A starting point the form asks them to correct, not an answer.
