Use this instead of Upload Media for large files and browser uploads — the bytes go directly to storage and never pass through the Dreep API. The flow is three steps:

POST /api/v1/upload/presign → returns an id and an uploadUrl.
PUT the raw file bytes to uploadUrl, with a Content-Type matching the contentType you declared.
POST /api/v1/upload/{id}/confirm to finalize the asset.

Until step 3 the asset stays pending and is excluded from media listings.

Destination

The destination folder is named exactly as it is for a direct upload — with folder, key, or folderId — and missing folders are created for you. When you pass a key, its last segment supplies the filename, so filename becomes optional. See Folders & Paths.

Skipping the upload for content Dreep already has

Send contentHash (the SHA-256 of the file). If it matches content already in storage, the response has "alreadyExists": true and no uploadUrl — skip the PUT and go straight to confirm.

The uploadUrl is short-lived and single-purpose. Generate it server-side and hand it to the client immediately; don’t cache or reuse it.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

contentType

string

required

Example:

"image/webp"

sizeBytes

integer

required

Example:

filename

string

Name to store the file under. Optional if key is given (its last segment supplies it), or if omitted entirely a name is generated for you.

Example:

"me.webp"

Available options:

true,

false
