Register Upload

storage_key returned by a prior POST /v1/uploads/url after the PUT completed.

Filename to record on the File row. Defaults to the basename embedded in storage_key.

MIME type to record on the File row. Defaults to the type the signed URL was originally bound to (inferred from the filename when not supplied).

Prefixed 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), as is the prefix over a UUID body (fld_00000000-0000-4000-8000-000000000000). All three are permanent, supported inputs; only the canonical form is ever emitted.

voice_source marks a transient recording: the seed of POST /v1/voices/similar or the source_audio of a speech-to-speech take. It always gets its own file (never a duplicate of one you already have, and never handed to another upload of the same bytes), stays out of My Media, and Moda deletes it 24 hours later (expires_at) unless a canvas, brand kit or other surface references it by then. Delete it yourself with DELETE /v1/drive/items/{id} once used. Omit for an ordinary, permanent upload.

Unique file identifier (prefixed file_...).

Stable proxy URL for the uploaded file. Use this in attachment URLs.

Filename of the uploaded file.

MIME type of the file.

File size in bytes.

True if an identical file already existed (deduplicated).

Prefixed 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), as is the prefix over a UUID body (fld_00000000-0000-4000-8000-000000000000). All three are permanent, supported inputs; only the canonical form is ever emitted.

ISO 8601 UTC time after which Moda deletes this transient upload (purpose voice_source), or null for a file that never expires.
