Lists the Merchant Center accounts the authenticated user can access. Returns accounts[] (name, accountId, accountName, languageCode, timeZone, adultContent, testAccount) and nextPageToken. Use it first to discover the account ID the other tools need (or set GOOGLE_MERCHANTS_ACCOUNT_ID once). Optional filter uses the account filter syntax, e.g. accountName = "store".

Returns a single Merchant Center account: name (accounts/{id}), accountId, accountName, languageCode, timeZone, adultContent and testAccount. Useful to verify the configured account or inspect a sub-account.

Returns the store homepage of an account: uri and claimed (whether the homepage is verified and claimed by the merchant — a prerequisite for serving offers). An unclaimed homepage is a common reason for account-level problems; claiming/unclaiming is not exposed as a tool (use raw_request POST accounts/v1/accounts/{a}/homepage:claim if you really need it).

Returns the account-level shipping settings: services[] (delivery countries, delivery times, rate tables and carrier rates), warehouses[] and an etag. Read-only by design: the API's only write is shippingSettings:insert, a FULL REPLACE of every service — too dangerous for a tool; use raw_request if you really need it.

Lists the processed products of an account, as shown in Merchant Center. Each product has name (accounts/{a}/products/{contentLanguagefeedLabelofferId} — NO channel segment in v1), offerId, contentLanguage, feedLabel, dataSource, productAttributes (title, price, availability, ...), productStatus with itemLevelIssues, and base64EncodedName (use it when offerId contains URL-hostile characters like '/'). The list has no server-side filter — filter via search_reports on product_view. Recently inserted products appear only after async processing (minutes).

Returns one processed product including productStatus.itemLevelIssues (code, severity, resolution, description) — the place to see why a product is disapproved. Identify the product either with product ("contentLanguagefeedLabelofferId", e.g. "enUSsku123", or the base64url base64EncodedName; legacy local products use a local~ prefix) or with the three components content_language + feed_label + offer_id. A product inserted moments ago may 404 until async processing finishes (minutes).

Uploads (upserts) a product into an API data source: an existing input with the same contentLanguagefeedLabelofferId in that data source is fully replaced. Requires data_source (an API-type source — create one with create_data_source or in Merchant Center; file feeds cannot be written). Inserting with a different data source MOVES the product to it. Returns the ProductInput (name, product = the future processed name, base64EncodedProduct). Processing is async: the processed product shows up in get_product/list_products after several minutes, and data-quality problems surface later in productStatus.itemLevelIssues, not as API errors. Prices go in product_attributes as {"price": {"amountMicros": "9990000", "currencyCode": "USD"}} (1 unit = 1,000,000 micros).

Sparse-updates an existing product input — the cheap way to change price or availability without re-sending the whole product. data_source must be the source holding the input. update_mask is a comma-separated list of attribute paths (e.g. "productAttributes.price,productAttributes.availability"); when omitted, all populated fields of the request are applied. Returns the updated ProductInput; the processed product refreshes after async processing (minutes). To create a product or replace it wholesale use insert_product_input.

Deletes a product input from a specific data source (data_source is required — the same product can exist in several sources, and only the targeted input is removed). product_input is "contentLanguagefeedLabelofferId" or the base64url name. Returns an empty object on success; the processed product disappears after async processing (minutes).

Lists the data sources of an account. Each has name (accounts/{a}/dataSources/{id}), dataSourceId, displayName, input (API | FILE | UI | AUTOFEED), exactly one type object (primaryProductDataSource, supplementalProductDataSource, promotionDataSource, ...) and fileInput for file feeds. Use it to find the API-type data source that insert_product_input / insert_promotion require as data_source.

Returns one data source by its numeric ID (or full resource name): type, input (API/FILE/UI/AUTOFEED), feed configuration and fetch settings. Check input before calling fetch_data_source — only file-based feeds with fetch settings can be re-fetched.

Creates an API (generic) data source — the target that insert_product_input / update_product_input / insert_promotion need as data_source. Only API sources can be created through the API (file, UI and autofeed sources are set up in Merchant Center). For product sources content_language and feed_label must be both set or both omitted; countries applies to primary sources only. A promotions source requires target_country and content_language. Returns the created DataSource with its dataSourceId.

Triggers an immediate re-fetch (re-read) of a file-based feed outside its regular schedule. Works only for data sources with a file input and fetch settings (scheduled fetch or Google Sheets); calling it on an API-type source is an error. Returns an empty object on success — the fetch itself runs asynchronously on Google's side.

Creates or updates a promotion. Unlike product writes, the data source travels in the request BODY (the server assembles it). The promotion object requires promotionId, contentLanguage (ISO 639-1), targetCountry (CLDR, e.g. "US") and redemptionChannel (array with ONLINE and/or IN_STORE — at least one). Optional attributes carry longTitle, couponValueType, offerType, genericRedemptionCode, promotionEffectiveTimePeriod {startTime, endTime}, productApplicability, moneyOffAmount, percentOff, etc. Returns the Promotion incl. promotionStatus; approval happens asynchronously (check get_promotion later).

Lists the promotions of an account: promotions[] (name, promotionId, contentLanguage, targetCountry, redemptionChannel, attributes, promotionStatus with destination statuses and itemLevelIssues) and nextPageToken.

Returns one promotion including promotionStatus (per-destination approval and itemLevelIssues) — the place to check whether a freshly inserted promotion was approved.

Runs a Merchant Center Query Language (MCQL) query via reports:search. Tables: product_view, product_performance_view, price_competitiveness_product_view, price_insights_product_view, non_product_performance_view, best_sellers_product_cluster_view, best_sellers_brand_view, competitive_visibility_top_merchant_view, competitive_visibility_competitor_view, competitive_visibility_benchmark_view. Rules: field names are snake_case in the query but camelCase in the JSON response; no SELECT ; performance views require a WHERE date range, e.g. SELECT offer_id, clicks, impressions FROM product_performance_view WHERE date BETWEEN '2026-07-01' AND '2026-07-31' ORDER BY clicks DESC. price_ views require the Market Insights opt-in. Each result row has exactly one populated view object. This is also the way to FILTER products (product_view) — list_products has no filter.

Convenience wrapper over a canned MCQL query on price_competitiveness_product_view: for each product, your price vs the market benchmark_price (aggregated from comparable offers across merchants) with report_country_code. A product priced above the benchmark is losing clicks to cheaper rivals. Requires the account to be opted into Market Insights (free, in Merchant Center settings) — otherwise rows are empty. Price amounts are micros (1,000,000 = 1 unit) and may arrive as strings (int64). Optional country narrows to one report country.

Convenience wrapper over a canned MCQL query on price_insights_product_view: Google's suggested_price per product with the predicted change in impressions, clicks and conversions if you adopt it (predicted_*_change_fraction, e.g. 0.05 = +5%), plus an overall effectiveness bucket (LOW/MEDIUM/HIGH). Requires the Market Insights opt-in — otherwise rows are empty. Price amounts are micros and may arrive as strings (int64).

Lists aggregate product statuses per reporting context and country (issueresolution sub-API): stats {active, pending, disapproved, expiring counts} plus itemLevelIssues[] with how many products each issue affects — the fastest way to see what is wrong with a feed at a glance. Works only for sub-accounts and standalone accounts, NOT for advanced (parent) accounts. The filter supports only reporting_context and country, e.g. reporting_context = "SHOPPING_ADS" AND country = "US". For a single product's issues use get_product (productStatus.itemLevelIssues).

Shows the account's Merchant API usage vs limits per method group (quota sub-API): quotaGroups[] with name, quotaUsage, quotaLimit (per day), quotaMinuteLimit and methodDetails[] listing the methods in each group. Daily counters reset at 12:00 UTC — midday, not midnight. Use it to diagnose HTTP 429 RESOURCE_EXHAUSTED errors and to see how much headroom is left.

Escape hatch to call any Merchant API v1 path directly, for endpoints without a dedicated tool (e.g. "accounts/v1/accounts/123/issues" or the one-time "accounts/v1/accounts/123/developerRegistration:registerGcp"). The path must include the sub-API prefix (accounts/v1, products/v1, datasources/v1, promotions/v1, reports/v1, issueresolution/v1, quota/v1, inventories/v1, ...). query adds URL query parameters (e.g. dataSource for productInputs writes, updateMask for PATCH); body is sent as JSON. Can create, modify and delete data — use the dedicated tools when one exists.
