Assets

Finalize an uploaded Asset

Completes a reserved Asset from the object that actually landed, and promotes it to ready.

This is the only real validation point: a presigned PUT carries no policy document, so nothing could have stopped the client sending a different type — or far more bytes — than it declared. A refused upload is deleted rather than left to bill as an orphan.

Pass advertiserId to place the file in the same call. That starts the same Registration as POST /assets/{id}/registrations, and it starts one only — the Registration settles later. The answer is the Asset either way. A registration that could not start does not fail this call, because the file is stored and only the registration needs retrying — read GET /assets/{id} for the Registration and its state.

post/assets/{id}/finalize

Request

  • Base URL: https://api.adcrunch.dev
  • URL: https://api.adcrunch.dev/assets/{id}/finalize
  • Auth: HTTP bearer

Path parameters

idstring required

The Asset the reservation made.

Request body

advertiserIdstring

Place the file in this advertiser’s library in the same call. Optional — send no body to store the file alone.

Example request

{
  "advertiserId": "acc_1203456789012345"
}

Response

The stored Asset, now ready. sizeBytes is read off the stored object. mimeType and kind are the declared type, verified against the stored bytes. width, height and durationMs are read from the header of the file. It carries no Registration, whether or not you asked for one.

contentHashstring required

AdCrunch’s own hash of the stored bytes. A hint for de-duplication, never an identity, and never a provider’s hash. Empty when the store reports none.

createdAtnumber required

Milliseconds since the Unix epoch, UTC.

createdBystring required

The user who reserved the upload.

deletedAtnumber nullable required

Always null here. A deleted Asset is not answered.

durationMsnumber nullable required

How long the video runs, in milliseconds, read from the header of the file at finalize. null for an image. For a video, null when the file does not state it, or for an Asset uploaded before AdCrunch read it.

filenamestring required

The name the file was uploaded under. Never a lookup key.

heightnumber nullable required

The height in pixels as the file is displayed, with its rotation applied, read from the header of the file at finalize. null when the file does not state it, or for an Asset uploaded before AdCrunch read it.

idstring required

The id of the Asset, ast_….

keystring required

Where the bytes are held. Read-only, and never sent by you.

kind'image' | 'video' required

Follows from mimeType, so the stored bytes verify it at finalize. It selects how a provider takes the file.

mimeTypestring required

The Content-Type the file was uploaded with, verified against the stored bytes at finalize.

namestring nullable required

The name a person gave this Asset, and what a provider receives at a future registration. null until somebody renames it, and the filename is the fallback.

organizationIdstring required

The organization that owns the Asset.

sizeBytesnumber required

Read from the stored object at finalize.

status'pending' | 'ready' required

ready once the bytes have been inspected. A pending Asset is a reservation whose bytes have not arrived, and no operation here answers one.

updatedAtnumber nullable required

When the Asset last changed, in milliseconds since the Unix epoch, UTC: at finalize, or at the last rename.

widthnumber nullable required

The width in pixels as the file is displayed, with its rotation applied, read from the header of the file at finalize. null when the file does not state it, or for an Asset uploaded before AdCrunch read it.
