Merchant API
– der offizielle Nachfolger der Content API for Shopping.
add_alert
Hinweis: Die Content API for Shopping wird am 18. August 2026 eingestellt.
Anfragen stellen
Mit Sammlungen den Überblick behalten
Sie können Inhalte basierend auf Ihren Einstellungen speichern und kategorisieren.
In diesem Leitfaden wird davon ausgegangen, dass Sie unseren Startleitfaden durchgearbeitet haben und autorisierte Anfragen stellen können.
Nachdem Sie alles eingerichtet haben, können Sie Anfragen an die Google Content API for Shopping senden. Die folgenden Codebeispiele zeigen, wie Sie einige einfache Anfragen senden:
- Erstellen Sie ein Produkt.
- Eine Liste der Produkte abrufen
- Ein bestimmtes Produkt aus der Liste abrufen
- Aktualisieren Sie den Preis eines Produkts.
Eine vollständige Liste der Methoden finden Sie in der
Referenzdokumentation.
Weitere Informationen finden Sie auf der Seite Best Practices, auf der die optimale Verwendung der API beschrieben wird.
Auf dieser Seite wird auch erläutert, warum Batchanfragen empfohlen werden.
Wenn Sie Probleme mit der Content API haben, sehen Sie im
Merchant Center-Status-Dashboard nach, ob es Ausfälle gibt, und rufen Sie die Supportseite auf.
Produkt erstellen
Eine vollständige Liste aller Attribute, die ein Produkt haben kann, finden Sie in der Produktfeedspezifikation.
Verwenden Sie den folgenden Code, um ein Produkt zu erstellen

$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);

"channel": "online",
"availability": "out of stock"
}
Java
Product product = new Product();
// Mandatory Fields
product.setOfferId("book123");
product.setContentLanguage("en");
product.setTargetCountry("GB");
product.setChannel("online");
// Optional Fields to Update
product.setAvailability("out of stock");
// Your unique supplemental feedId
feedId=123456789
Product result = service.products().insert(merchantId, product, feedId).execute();
PHP
$product = new Google_Service_ShoppingContent_Product();
// Mandatory Fields
$product->setOfferId('book123');
$product->setContentLanguage('en');
