Making Requests

This guide assumes you've worked through our Getting Started guide and are set up to make authorized requests.

After you've set everything up, you can send requests to the Google Content API for Shopping. The following code samples demonstrate how to send a few simple requests:

  • Create a product.
  • Get a list of products.
  • Retrieve a specific product from the list.
  • Update a product's price.

For a full list of methods, see the reference documentation.

For more information, see the Best Practices page, which explains how to best use the API. This page also explains why batch requests are recommended.

Create a product

You can find full details of all the attributes that a product can have in the Products Feed Specification. To create a product, use the following code:

Protocol

POST /content/v2/YOUR_MERCHANT_ID/products

{
  "offerId": "book123",
  "title": "A Tale of Two Cities",
  "description": "A classic novel about the French Revolution",
  "link": "http://my-book-shop.com/tale-of-two-cities.html",
  "imageLink": "http://my-book-shop.com/tale-of-two-cities.jpg",
  "contentLanguage": "en",
  "targetCountry": "GB",
  "channel": "online",
  "availability": "in stock",
  "condition": "new",
  "googleProductCategory": "Media > Books",
  "gtin": "9780007350896",
  "price": {
    "value": "2.50",
    "currency": "GBP"
  },
  "shipping": [{
    "country": "GB",
    "service": "Standard shipping",
    "price": {
      "value": "0.99",
      "currency": "GBP"
    }
  }],
  "shippingWeight": {
    "value": "200",
    "unit": "grams"
  }
}

Java

Product product = new Product();

product.setOfferId("book123");
product.setTitle("A Tale of Two Cities");
product.setDescription("A classic novel about the French Revolution");
product.setLink("http://my-book-shop.com/tale-of-two-cities.html");
product.setImageLink("http://my-book-shop.com/tale-of-two-cities.jpg");
product.setContentLanguage("en");
product.setTargetCountry("GB");
product.setChannel("online");
product.setAvailability("in stock");
product.setCondition("new");
product.setGoogleProductCategory("Media > Books");
product.setGtin("9780007350896");

Price price = new Price();
price.setValue("2.50");
price.setCurrency("GBP");
product.setPrice(price);

Price shippingPrice = new Price();
shippingPrice.setValue("0.99");
shippingPrice.setCurrency("GBP");

ProductShipping shipping = new ProductShipping();
shipping.setPrice(shippingPrice);
shipping.setCountry("GB");
shipping.setService("Standard shipping");

ArrayList shippingList = new ArrayList();
shippingList.add(shipping);
product.setShipping(shippingList);

Product result = service.products().insert(merchantId, product).execute();

PHP

$product = new Google_Service_ShoppingContent_Product();
$product->setOfferId('book123');
$product->setTitle('A Tale of Two Cities');
$product->setDescription('A classic novel about the French Revolution');
$product->setLink('http://my-book-shop.com/tale-of-two-cities.html');
$product->setImageLink('http://my-book-shop.com/tale-of-two-cities.jpg');
$product->setContentLanguage('en');
$product->setTargetCountry('GB');
$product->setChannel('online');
$product->setAvailability('in stock');
$product->setCondition('new');
$product->setGoogleProductCategory('Media > Books');
$product->setGtin('9780007350896');

$price = new Google_Service_ShoppingContent_Price();
$price->setValue('2.50');
$price->setCurrency('GBP');

$shipping_price = new Google_Service_ShoppingContent_Price();
$shipping_price->setValue('0.99');
$shipping_price->setCurrency('GBP');

$shipping = new Google_Service_ShoppingContent_ProductShipping();
$shipping->setPrice($shipping_price);
$shipping->setCountry('GB');
$shipping->setService('Standard shipping');

$shipping_weight = new Google_Service_ShoppingContent_ProductShippingWeight();
$shipping_weight->setValue(200);
$shipping_weight->setUnit('grams');

$product->setPrice($price);
$product->setShipping(array($shipping));
$product->setShippingWeight($shipping_weight);

$result = $service->products->insert($merchant_id, $product);

Get a list of products

To get a list of products, use the following code:

Protocol

GET /content/v2/YOUR_MERCHANT_ID/products

Java

List productsList = service.products().list(merchantId);

ProductsListResponse page = productsList.execute();
while ((page.getResources() != null) && !page.getResources().isEmpty()) {
  for (Product product : page.getResources()) {
    System.out.printf("%s %s%n", product.getId(), product.getTitle());
  }

  if (page.getNextPageToken() == null) {
    break;
  }

  productsList.setPageToken(page.getNextPageToken());
  page = productsList.execute();
}

PHP

$products = $service->products->listProducts($merchantId);
$parameters = array();
while (!empty($products->getResources()) {
  foreach ($products->getResources() as $product) {
    printf("%s %s\n", $product->getId(), $product->getTitle());
  }
  if (!empty($products->getNextPageToken()) {
    break;
  }
  $parameters['pageToken'] = $products->nextPageToken;
  $products = $service->products->listProducts($merchantId, $parameters);
}

Retrieve a specific product

To retrieve a specific product from the list, use the following code:

Protocol

GET /content/v2/YOUR_MERCHANT_ID/products/online:en:GB:book123

Java

Product product = service.products()
    .get(merchantId, "online:en:GB:book123")
    .execute();
System.out.printf("%s %s\n", product.getId(), product.getTitle());

PHP

$product = $service->products->get($merchant_id, 'online:en:GB:book123');
printf("%s %s\n", $product->getId(), $product->getTitle());

Update product price

You can use the Inventory service to update price and availability with the following code:

Protocol

POST /content/v2/YOUR_MERCHANT_ID/inventory/online/products/online:en:GB:book123

{
  "price": {
    "value": "3.99",
    "currency": "USD"
  }
}

Java

InventorySetRequest inventory = new InventorySetRequest();

Price price = new Price();
price.setValue('3.99');
price.setCurrency('USD');

inventory.setPrice(price);

service.inventory()
    .set(merchantId, "online", "online:en:US:book1", inventory)
    .execute();

PHP

$inventory = new Google_Service_ShoppingContent_InventorySetRequest();

$price = new Google_Service_ShoppingContent_Price();
$price->setValue('3.99');
$price->setCurrency('USD');

$inventory->setPrice($price);

$service->inventory->set(merchant_id, 'online', 'online:en:US:book1', $inventory);
