Create Folder
Create a drive folder (team-visible; nested when parent_folder_id is set).
Name conflicts are a 409 folder_name_conflict whose details carry
existing_folder_id when the caller can see the conflicting folder — an
agent re-running “create the project folder” should adopt that id rather
than invent a suffixed name.

Headers
Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.

Body
Folder display name (unique per location).
1 - 255Prefixed fld_ wire ID (Crockford base32 body) — the canonical, recommended form. For back-compat, a bare UUID string is also accepted in both path parameters and JSON request bodies (older integrations that stored raw UUIDs keep working). Both are permanent, supported inputs.

A retried create with the same key replays the stored result instead of failing on the name-conflict of its own earlier success. Use a fresh random key per intended create.
