Merchant API Service

The Merchant API service lets you use the Merchant API in Apps Script, to upload products and manage Merchant Center accounts.

For detailed information about the Merchant API, see the reference documentation. Like all advanced services in Apps Script, the Merchant API service uses the same objects,methods, and parameters as the public API.

The Merchant API is a collection of sub-APIs, which are groups of related services and resources. Here's the list of sub-APIs.

To use the Merchant API service in Apps Script, follow these steps:

  1. Make sure that your Apps Script project is linked to a standard Google Cloud project.

  2. Enable the Apps Script Advanced service, as described in this document:

    • Enable appsscript.json for new projects.
    • Enable Apps Script for existing projects.

  3. Register your standard Google Cloud project with your Merchant Center account, as described in the Merchant API quickstart.

Enable Apps Script Advanced service

You can enable the Apps Script service using either of the following two methods:

Enable APIs in appsscript.json

The following example shows an appsscript.json file that enables the Products, Accounts, Reports, and Data sources sub-APIs.

  1. In the Apps Script editor, select Project Settings .

  2. Enable the Show "appsscript.json" manifest file in editor option.

  3. In the editor, select the appsscript.json file.

  4. Replace the contents of your appsscript.json file with the following:

    {
  "dependencies": {
    "enabledAdvancedServices": [
      {
        "userSymbol": "MerchantApiAccounts",
        "version": "accounts_v1beta",
        "serviceId": "merchantapi"
      },
      {
        "userSymbol": "MerchantApiDataSources",
        "version": "datasources_v1beta",
        "serviceId": "merchantapi"
      },
      {
        "userSymbol": "MerchantApiProducts",
        "version": "products_v1beta",
        "serviceId": "merchantapi"
      },
      {
        "userSymbol": "MerchantApiReports",
        "version": "reports_v1beta",
        "serviceId": "merchantapi"
      }
    ]
  },
  "exceptionLogging": "STACKDRIVER",
  "runtimeVersion": "V8"
}
    appsscript.json

  5. Click Save.

  6. You can now refer to the following sub-APIs within your code as:

    a. MerchantApiAccounts

    b. MerchantApiDataSources

    c. MerchantApiProducts

    d. MerchantApiReports

Enable Apps Script for additional sub-APIs or existing projects

To enable sub-APIs in existing projects, do the following:

  1. Open your Apps Script project.

  2. At the left, click Editor < >.

  3. At the left, next to Services, click Add a service +.

  4. Select the sub-API you want to enable within the version selector.

  5. Append the identifier with name of your sub-API. For example, to enable the Inventories sub-API, select version inventories_v1beta and change the identifier to MerchantApiInventories.

  6. You can now refer to Inventories sub-API within your code as MerchantApiInventories.

Sample code

This section explains how to use Merchant API for selected features.

List the products

This example demonstrates how to list the products for a given Merchant Center account.


/**
 * Lists all products for a given Merchant Center account.
 */
function productList() {
  // IMPORTANT:
  // Enable the Merchant API Products Bundle Advanced Service and call it
  // "MerchantApiProducts"

  // Replace this with your Merchant Center ID.
  const accountId = '<MERCHANT_CENTER_ID>';

  // Construct the parent name
  const parent = 'accounts/' + accountId;

  try {
    console.log('Sending list Products request');
    let pageToken;
    // Set the page size to 1000. This is the maximum allowed page size.
    let pageSize = 1000;

    console.log('Retrieved products below:');
    // Call the Products.list API method. Use the pageToken to iterate through
    // all pages of results.
    do {
      response = MerchantApiProducts.Accounts.Products.list(parent, {pageToken, pageSize});
      console.log(response);
      pageToken = response.nextPageToken;
    } while (pageToken); // Exits when there is no next page token.
  } catch (e) {
    console.log('ERROR!');
    console.log(e);
  }
}

Filter disapproved products

This example demonstrates how to filter disapproved products in a Merchant Center account.


/**
 * Demonstrates how to filter disapproved products using the Merchant API Reports service.
 */
function filterDisapprovedProducts() {
  // IMPORTANT:
  // Enable the Merchant API Reports Bundle Advanced Service and call it
  // "MerchantApiReports"
  // Enable the Merchant API Products Bundle Advanced Service and call it
  // "MerchantApiProducts"

  // Replace this with your Merchant Center ID.
  const accountId = '<INSERT_MERCHANT_CENTER_ID>';

  // Construct the parent name
  const parent = 'accounts/' + accountId;

  try {
    console.log('Sending search Report request');
    // Set pageSize to the maximum value (default: 1000)
    let pageSize = 1000;
    let pageToken;
    // The query below is an example of a query for the productView that gets product informations
    // for all disapproved products.
    let query = 'SELECT offer_id,' +
        'id,' +
        'price,' +
        'title' +
        ' FROM product_view' +
        ' WHERE aggregated_reporting_context_status = "NOT_ELIGIBLE_OR_DISAPPROVED"';


    // Call the Reports.search API method. Use the pageToken to iterate through
    // all pages of results.
    do {
      response =
          MerchantApiReports.Accounts.Reports.search({query, pageSize, pageToken}, parent);
      for (const reportRow of response.results) {
        console.log("Printing data from Product View:");
        console.log(reportRow);

        // OPTIONALLY, you can get the full product details by calling the GetProduct method.
        let productName = parent + "/products/" + reportRow.getProductView().getId();
        product = MerchantApiProducts.Accounts.Products.get(productName);
        console.log(product);
      }
      pageToken = response.nextPageToken;
    } while (pageToken);  // Exits when there is no next page token.

  } catch (e) {
    console.log('ERROR!');
    console.log('Error message:' + e.message);
  }
}
