Send your feed to Google Merchant Center

Get your Shopify products into Google Merchant Center, either through a direct API connection or through a feed URL that Google fetches.


Use this when: you have a Merchant Center account and want your products in Google Shopping, free listings or Performance Max ads.


  1. Before you start
  2. Connect with the API
  3. Add an XML feed
  4. Limits


Before you start


  • You have a Google Merchant Center account, and your Google login has Admin or Standard access to it.
  • Your store's website is claimed and verified in Merchant Center. See Claim your website.
  • Pick a sync method. The API is recommended: you see each product's approval status and fix issues inside Omega Feed. An XML feed suits you if you prefer to manage the upload in Merchant Center yourself.


Connect with the API


  1. Go to Feeds and open the Google Shopping tab.
  2. Click Create new feed.
  3. In Create a new feed, under How to sync, choose Direct channel connection (API), then click Create.

  1. A Google sign-in window opens. Sign in with the Google account that has access to your Merchant Center.
  2. On the consent screen, keep every checkbox selected and finish the sign-in.


When you see Account connected, Omega Feed opens the new feed. If you already connected a Google account, step 4 is skipped.


If the sign-in fails, the app shows a Connection error window with an error code. Look up the code in Can't connect Google or Meta.


  1. In the Google account card, choose your Merchant Center in Merchant Center Account.
  2. In Choose data source, pick an existing data source or keep Create new source.

Google account card with Merchant Center Account and Choose data source

  1. If you create a new source, check Feed label. Use A–Z, 0–9, - and _, up to 20 characters.
  2. Enter a Feed name (up to 50 characters).
  3. Set up the rest of the feed (market, products, schedule) as described in Create a feed, then save.


Omega Feed starts pushing products to Merchant Center as soon as you save. New products wait for Google's review before they show in ads.


The feed label can't be changed after the feed is created. If another data source in the same Merchant Center sends a product with the same ID, feed label and language, Google keeps only one of them. Give each feed its own label.


If the Your GMC account is not verified banner appears, click Verify account now and finish verification in Merchant Center. Products won't be approved until the account is verified.


Add an XML feed


Create the feed in Omega Feed


  1. Go to Feeds and open the Google Shopping tab.
  2. Click Create new feed.
  3. Under How to sync, choose Export a data file, then click Create.
  4. Set up the feed as described in Create a feed and save. Google reads XML or TSV (tab-separated) files.


Copy the feed URL


  1. When the file is ready, a window titled Congratulations! Your first feed is live. shows the Feed URL. Click Copy.
  2. Later, copy it again from the feed's row: click Feed actions (the ⋯ button) and choose Copy feed URL.


While the file is being built, the app shows Generating feed URL.... Wait until a link appears.


Add the URL in Merchant Center


  1. Click Open Merchant Center in the same window, or open Merchant Center and go to the page for adding a product source.
  2. Choose Add products from a file (not Shopify).
  3. Choose to fetch the file from a link on a schedule, and paste the feed URL.
  4. Set the fetch frequency to daily, at a time after your feed's auto-sync.
  5. Leave the username and password empty, unless you turned on Require login details for this feed. See Protect your feed URL.
  6. Save the data source.

Each sync replaces the file at the same URL, so you paste it only once. After Google fetches the file, the feed's status in Omega Feed changes from Never fetched to Uploaded.


XML feed errors appear in Merchant Center, not in Omega Feed. Use the API if you want to see and fix issues inside the app.


Limits


  • Number of feeds and products per plan: see Plan limits.
  • Connecting more than one Google account needs the Advanced plan.
  • Real-time price and stock updates work with API feeds only, on Scale and Advanced.
  • Google reviews new products before they show. The app shows Pending approval until Google answers, which can take from a few minutes to a few days.
