# Save

> You can save a product state to Asset Storage by using the `POST ~/api/product/save` endpoint. This endpoint accepts a product object, `userId`, and `stateId`, and returns an array of origin file URLs and the `stateId`.

## Request Payload

To save a product, pass the product data, `userId`, and `stateId` in the request body:

```json
{
    "product": {
        "surfaces": [
            {
                "printAreas": [
                    {
                        "design": {
                            "file": "425a3537-2e59-450d-bbc2-484fcd3d63bd.pdf"
                        }
                    }
                ]
            }
        ]
    },
    "userId": "user@example.com",
    "stateId": "4afcbe97-b51d-4f6f-b9db-70c55536b80a"
}
```

```javascript
const saveProduct = async () => {
    const response = await fetch(appUrl + "api/product/save", {
        method: "POST",
        body: JSON.stringify({
            product: {
                surfaces: [
                    {
                        printAreas: [
                            {
                                design: {
                                    file: "425a3537-2e59-450d-bbc2-484fcd3d63bd.pdf"
                                }
