How to Connect Google Merchant Center to ChatGPT (2 Steps, No Code)

You can connect Google Merchant Center to ChatGPT in two no-code steps using the Windsor.ai plugin: authorize your Merchant Center account once in Windsor.ai, then add the Windsor.ai plugin in ChatGPT. ChatGPT then pulls your product data when you ask. The Google Merchant Center to ChatGPT integration page gives the short version.

Google has no Merchant Center plugin of its own in ChatGPT. It documents a Merchant API MCP server (alpha) for AI agents and coding assistants; the section "Is there an official Google Merchant Center app for ChatGPT?" below lists the routes that work.

If you sell through Google Shopping and free listings, your Google Merchant Center account holds the impressions, clicks and status of each product.

Performance marketers want to know which products are winning, which have feed or availability problems, and where the next unit of Shopping budget should go.

Connecting Google Merchant Center to ChatGPT with the Windsor.ai plugin: 2 steps

The whole setup takes about a minute and needs no code. You connect your data to Windsor.ai, then add the Windsor.ai plugin in ChatGPT.

📚 Full documentation: How to integrate your data into ChatGPT.

Before you start

• A Google Merchant Center account with product data, and a Google sign-in that has access to it.
• A Windsor.ai account. The free forever plan covers 1 user, 1 data source and 1 account with the last 30 days of data, and needs no credit card. Paid plans start at $19/month for 3 sources, billed annually (pricing).
• A ChatGPT account. We used ChatGPT’s Free plan for the steps on this page. In a Business, Enterprise or Edu workspace, an admin can turn plugins on or off.

Step 1. Connect Google Merchant Center to Windsor.ai

Go to onboard.windsor.ai/app/google_merchant, sign in, and authorize access to your Merchant Center account. Select the account(s) you want to pull from. Tracking more than one account needs a paid plan. The free forever plan includes 1 account. Windsor.ai pulls and organizes the data, ready to analyze in ChatGPT.

Step 2. Add the Windsor.ai plugin in ChatGPT

Open the Windsor.ai plugin page in ChatGPT and click Connect, or Install plugin if that is the button you see. You can also click Plugins in the ChatGPT sidebar and search for Windsor.ai. Grant access when ChatGPT asks. To disconnect later, open Settings, then Plugins.

In a new chat, click + and choose Windsor.ai, or type @Windsor and pick it from the list. To check the connection, ask:

Which Google Merchant Center accounts am I connected to, and what were my total clicks and impressions for the last 7 days?

Windsor.ai also has four write actions for Google Merchant Center: insert_product, update_product, delete_product and create_data_source. You can ask ChatGPT to add, update or delete products in an API data source, pause a product, or create a new data source, from the same chat. Merchant Center changes products only in API data sources: for products from a file feed, the update goes to a supplemental API data source linked to that feed. See the full list of write actions.

Try this prompt: your products by impressions in ChatGPT

In a chat with the Windsor.ai plugin, ask:

For my Google Merchant Center account, list the 10 products with the most impressions in the last 30 days, with clicks and CTR for each, plus the totals for the account. Which product has the lowest CTR among them?

ChatGPT answers from product_title, product_impressions, product_clicks and product_ctr. A product with many impressions and a low CTR is the first one to check for its title, image and price.

Is there an official Google Merchant Center app for ChatGPT?

No. ChatGPT’s Plugins directory has no Merchant Center plugin from Google (checked 4 November 2026). Google documents a Merchant API MCP server, which is in alpha. These are the routes that work, and when each fits:

• Windsor.ai plugin: reads your product performance, product attributes, prices and product statuses when you ask, and can add, update, pause or delete products in an API data source after you confirm (write actions list). Use it for ongoing questions, or to ask about Merchant Center together with Google Ads, GA4 or Shopify in one chat. The Plugins directory also lists a dedicated Windsor.ai plugin, "W. Google Merchant Center" ("Analyze Google Merchant Center"); the steps on this page use the main Windsor.ai plugin.
• Google’s Merchant API MCP server: Google’s own server, in alpha, with read tools (including product statuses and the aggregated reasons for product disapprovals) and low-risk write tools such as creating a data source. It needs a Google Cloud project associated with your Merchant Center account and OAuth 2.0 or service account credentials. Google’s guide covers Antigravity, Claude’s command line tool and cURL with an access token; it does not cover ChatGPT (Google’s guide). In ChatGPT, full support for a custom MCP server, including tools that change data, is limited to Business, Enterprise and Edu workspaces; Pro gets read and fetch tools only. It fits teams that need the disapproval reasons and can set up a Google Cloud project.
• Other third-party plugins and MCP servers: other developers publish Merchant Center tools. Check which data and which write permissions each one asks for.
• Merchant Center reports: copy the figures from a Merchant Center report into a chat. It fits one question about a fixed period; the figures do not update.
• Google Sheets: send Merchant Center data to a sheet on a schedule with Windsor.ai (Google Merchant Center to Google Sheets), and point ChatGPT or a dashboard at that copy. It fits shared reports that keep their own history.

The metrics that matter for Google Merchant Center

Google Merchant Center has 150 fields through Windsor.ai, and you can browse the complete list on the Google Merchant Center data fields page. These are the ones most performance marketers reach for first:

• product_clicks: How many times shoppers clicked your products.
• product_impressions: How often your products were shown.
• product_ctr: Click-through rate (clicks divided by impressions), how compelling each listing is.
• product_conversions: Purchases or tracked actions credited to a product. Merchant Center reports them for free listings only.
• product_conversion_rate: Share of clicks that convert, a quick quality signal per product, for free listings only.
• product_id: The unique product (offer) ID from your feed, which joins to your catalog.
• product_title: Product title exactly as it appears in your feed.
• product_brand: Brand of the product, from your product attributes.
• product_type_l1: Your own top-level product category from the feed taxonomy.
• product_price: The listed price of the product in your feed.
• product_availability: Availability status, for example in stock or out of stock.
• product_benchmark_price and product_price_gap: Google’s latest price benchmark for the product in the benchmark country, and the percentage difference between your price and the benchmark.
• product_status_disapproved_count: How many products are disapproved for each destination (product_status_reporting_context, for example Shopping ads or free listings) and country, next to the active, pending and expiring counts.
• date: The day each metric belongs to, for trends and period-over-period comparisons.

What to ask ChatGPT about your Google Merchant Center data: prompt ideas

Find your winners and losers

Show me my Google Merchant Center product performance for the last 30 days, including clicks and impressions by product.

Which 10 products have the most impressions but the lowest conversion rate from free listings in the last 30 days? These are my biggest optimization opportunities.

Catch feed and availability problems

List my products that are currently out of stock, with their product name, link and availability.

How many of my products are currently in stock, out of stock, on preorder or on backorder?

Prioritize by category

Rank my product categories by conversions from free listings for the last 30 days, and show clicks and conversion rate for each.

Which product types (product_type_l1) got the most impressions but the lowest CTR in the last 30 days?

Show me the week-over-week change in clicks and conversions for my top 20 products by clicks.

Bonus: analyze Google Merchant Center alongside your full marketing stack

Windsor.ai brings 350+ data sources into one ChatGPT conversation, so you can ask about your products together with your other channels.

The same Windsor.ai connection reaches these sources too.

• Google Merchant Center + Google Ads: compare Shopping and Performance Max spend against product feed performance, to see where budget and product demand line up and where they do not.
• Google Merchant Center + GA4: see which products earn clicks in Shopping and then convert on site, and optimize the feed around on-site behavior.
• Google Merchant Center + Shopify: check feed health and availability against Shopify orders, to find out-of-stock or mispriced products that still get impressions.

Combining sources needs a paid plan. The free forever plan includes 1 data source.

If something does not work

• A Merchant Center account is missing: sign in to Windsor.ai with a Google account that has access to that Merchant Center account, then select it on the connect page. Tracking more than one account needs a paid plan. The free forever plan includes 1 account.
• ChatGPT says no Merchant Center accounts are configured, or the Google sign-in failed: Google’s access was revoked or expired. Open onboard.windsor.ai/app/google_merchant, sign in with Google again and select the account.
• ChatGPT answers without your Merchant Center data: choose Windsor.ai under + or type @Windsor in that chat, then ask again.
• Windsor.ai shows "Disabled by admin": your ChatGPT workspace admin has turned the plugin off. Ask them to enable it.
• Conversions are empty for products that sell through Shopping ads: Merchant Center reports conversions for free listings only. For ad conversions per product, ask about Google Ads in the same chat.
• ChatGPT cannot change a product from your file feed: write actions change products only in API data sources. Ask ChatGPT to create a supplemental API data source linked to the feed, then update the product there.

The Google Merchant Center to ChatGPT integration page gives the short answers and a second prompt, product statuses by destination and prices against Google’s benchmark. The same Windsor.ai connection also works in Claude, as described in how to sync Google Merchant Center to Claude.

Conclusion

With Google Merchant Center connected to ChatGPT through the Windsor.ai plugin, you can ask which products get impressions and clicks, which are out of stock, how many are disapproved for each destination, and how your prices compare with Google’s benchmark. Start with the check prompt in Step 2, then try the prompt above on your own account.

Setup is two steps and no code. Add Google Ads, GA4 or Shopify on a paid plan to ask about them in the same chat. For more ideas, see how to use Windsor.ai for e-commerce.
