## Complete upload

**post** `/uploads/{upload_id}/complete`

Completes the [Upload](/api/reference/resources/uploads).

Within the returned Upload object, there is a nested [File](/api/reference/resources/files) object that is ready to use in the rest of the platform.

You can specify the order of the Parts by passing in an ordered list of the Part IDs.

The number of bytes uploaded upon completion must match the number of bytes initially specified when creating the Upload object. No Parts may be added after an Upload is completed.
Returns the Upload object with status `completed`, including an additional `file` property containing the created usable File object.

### Path Parameters

### Body Parameters

- `part_ids: array of string`

- `md5: optional string`

  The optional md5 checksum for the file contents to verify if the bytes uploaded matches what you expect.

### Returns

- `Upload object { id, bytes, created_at, 6 more }`

  The Upload object can accept byte chunks in the form of Parts.

  - `id: string`

    The Upload unique identifier, which can be referenced in API endpoints.

  - `bytes: number`

  - `created_at: number`
