Batch Complete Upload

POST 
/v1/:slug/assets/batch_upload_complete

Final Step of Batch Asset Upload Process

Completes a batch upload by creating Asset records for all uploaded files. Each asset is created individually — a failure mid-batch does not roll back previously created assets.

{
  "batch": {
    "batch_id": "uuid-from-batch_upload_prepare",
    "collection_token": "optional-collection-token",
    "assets": [
      {
        "uuid": "client-uuid-1",
        "signed_gcs_id": "value-from-prepare",
        "title": "photo.jpg",
        "media_type": "image/jpeg",
        "width": 1920,
        "height": 1080
      }
    ]
  }
}

Important​

  • signed_gcs_id must be the exact value from batch_upload_prepare
  • batch_id is optional but recommended — it releases the upload reservation
  • For Backblaze multipart uploads, include multipart_upload_id
  • Maximum 100 assets per batch
