After you authorize a Connector, Marrow obtains **read-only** access, extracts data from the platform APIs, normalizes it into a consistent schema, and keeps it updated through scheduled syncs. See [Data Fetch Periods](./Data%20Fetch%20Periods.md) for how often refreshes run. The full list of tables and columns for your connections is in **Data Schema** (also reachable from Data Explorer). ## Which platforms does Marrow support? Marrow’s Integrations cover the store and ad platforms below. Some are **actively synced** into the Marrow data layer today; others are **available or expanding**—you can connect them in Integrations as coverage rolls out. Always check Data Schema for the tables currently available on your account. ### Actively synced into Marrow Data These platforms have ongoing ETL into Marrow tables: | Integration | Source APIs | Typical data coverage | | -------------------------- | -------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Amazon Seller** | [Amazon Selling Partner API (SP-API)](https://developer-docs.amazon.com/sp-api) | Marketplaces, orders & order items, listings & catalog, FBA inventory & logistics, returns, sales & traffic, Brand Analytics, promotions & coupons, seller performance & feedback, finance & settlements | | **Amazon Vendor** | [Amazon Selling Partner API (SP-API)](https://developer-docs.amazon.com/sp-api) | Listings & catalog, purchase orders & shipments, direct fulfillment, vendor sales, traffic, inventory, margin, and forecasting reports | | **Amazon Ads** | [Amazon Ads API](https://advertising.amazon.com/API/docs/en-us/reference/api-overview) | Profiles & portfolios; Sponsored Products, Brands, and Display entities; daily performance reports; AMC-related metadata where enabled | | **Google Ads** | Google Ads API | Customers, campaigns, ad groups, ads, keywords, and daily performance metrics (including search terms where available) | | **Google Analytics (GA4)** | Google Analytics Data API | Accounts, properties, data streams, and daily overview / traffic / page / event metrics | | **Google Search Console** | Search Console API | Sites and Search Analytics | | **Shoplazza** | Shoplazza Admin API | Shop, products & collections, customers, orders, transactions & refunds, discounts, and store analytics | ### Available or expanding These Integrations appear in Marrow’s product lineup. Connect them from **Integrations** when offered for your account; table-level sync coverage may still be rolling out. Use Data Schema to confirm what is stored for you—do not assume every UI connection already has a full daily table set. | Integration | Notes | | --------------------------- | ---------------------------------------------------------------------------- | | **Shopify** | Store commerce data for Shopify merchants; schema coverage expands over time | | **Facebook Ads (Meta Ads)** | Paid social performance for advertisers aggregating Meta with other channels | | **Amazon DSP** | Demand-side advertising coverage beyond Sponsored ads | | **Lingxing ERP** | ERP operational context alongside marketplace and ads data | ## What kinds of business data does Marrow include? Across actively synced platforms, Marrow focuses on operator-ready categories such as: * **Sales & traffic** — orders, ASIN- or product-level sales, sessions, conversion-oriented metrics * **Inventory & logistics** — FBA / warehouse health, shipments, returns where the platform provides them * **Advertising** — campaign structure and daily performance for Amazon Ads and Google Ads * **Finance** — settlements, fees, and related money movement on supported Amazon Seller flows * **Catalog & listings** — products, attributes, and listing state * **Web & search analytics** — GA4 daily metrics and Google Search Console performance * **Vendor operations** — POs, shipments, and vendor reports for Amazon Vendor Ultra-high-volume, low-signal slices (for example Google Ads hourly click or campaign hourly stats) are intentionally out of scope so schemas stay usable and row costs stay predictable. ## Why does Marrow curate endpoints and reports? Store and ad platforms expose hundreds of reports and endpoints. Many overlap, change often, or return shapes that are hard to use in analysis or AI tools. Marrow selects the sources that map to real seller and advertiser workflows, normalizes field names and keys, and stores them in PostgreSQL-backed tables you can query through MCP and AI platforms. Related concepts—orders and settlements, ads and sales, listings and inventory—are aligned so you spend less time cleaning data yourself. ## Request more data sources We keep adding platforms, reports, and tables. If you need a source or metric that is missing, contact Marrow support and tell us which platform, account type, and business question you are trying to answer. ## Related pages * [Data Fetch Periods](./Data%20Fetch%20Periods.md) — when data refreshes * [Timezones](./Timezones.md) — marketplace local dates vs UTC timestamps * [Managing Data Tables](./Managing%20Data%20Tables.md) — how tables make up your data layer
