# onMultiArtworkCreate

Registers a callback that runs when a user finishes proofing their design.

**Tip:** The Partnership SDK refers to a proofed design as an *artwork*.

## Usage

```js
(async () => {
  const api = await Canva.Partnership.initialize({
    apiKey: "<partner_api_key>",
    autoAuthToken: "<auto_auth_token>",
    container: document.getElementById("container"),
  });

  const onMultiArtworkCreate = (opts) => {
    opts.artworks.forEach((artwork) => {
      console.log(artwork);
    });
  };

  const onProductSelect = (opts) => {
    api.createDesign({
      ...opts,
      onMultiArtworkCreate,
    });
  };

  api.showCatalog({
    onProductSelect,
  });
})();
```

| `previewImages`                | Array\<string> |    Yes   |    Yes   | A list of URLs for previewing a low-resolution version of the artwork.

The URL is in the form `https://partnership-artwork.canva.com/<export_file>`. If you're using the China version of the SDK, the TLD is `.cn` instead of `.com`. You can take the necessary security measures to protect the URL from any malicious attacks.                                                        |

| `partnerProductId`             | string         |    Yes   |    No    | The ID of a product in Canva's back-end.

A partner may provide a partner product ID to Canva beforehand. This may match with a product ID in a partner's back-end, such as SKU or internal system identifier. If partner doesn't provide a partner product ID, Canva assigns one for each product. |
