get-assets

Get names, tags, types, and thumbnails for images and videos used in a design.

Use get-assets to look up the images or videos on a page, for example to work out which one the user means before changing it. Asset IDs come from the fills returned by start-editing-transaction.

Example prompt

"Which of the photos on slide 3 is the team photo? Swap that one out."

Pass asset_ids, an array of image or video IDs.

Example response

IDs, URLs, and tokens below are placeholders; field names and structure are exactly as returned.

The result is a list of content blocks rather than one JSON value. For each requested ID, in the order you supplied them, there's a text block holding that asset's JSON, followed by an image block with the asset itself when the lookup succeeded. A request for two IDs where the second can't be found returns three blocks:

  1. A text block for the first ID:

    {
    "asset": {
    "type": "image",
    "id": "ASSET_EXAMPLE_1",
    "name": "Team photo",
    "tags": ["team", "offsite"],
    "created_at": 1758000000,
    "updated_at": 1758000000,
    "owner": { "user_id": "USER_EXAMPLE", "team_id": "TEAM_EXAMPLE" },
    "thumbnail": {
    "width": 595,
    "height": 335,
    "url": "https://document-export.canva.com/EXAMPLE_THUMBNAIL"
    },
    "import_status": { "state": "success" },
    "metadata": { "type": "image", "width": 1920, "height": 1080, "smart_tags": ["people", "outdoors"] }
    }
    }
    JSON
  2. An image block containing the first asset's image data.

  3. A text block for the second ID:

    { "error": { "code": "asset_not_found", "message": "<human-readable description>" } }
    JSON

asset.type is image or video, and metadata carries the dimensions (and duration for videos) when available. The call succeeds as a whole even if individual assets fail, so check each text block.

Thumbnail URLs expire after 15 minutes. Use them immediately, and don't store or share them.
