It is built from Walmart Marketplace's documentation as read on 23 October 2026. 190 actions in 72 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Walmart Marketplace data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Walmart Marketplace credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like Walmart Marketplace Shares the most action names with - [ShipStation 16](https://actionlake.com/connectors/shipstation) - [ShipBob 15](https://actionlake.com/connectors/shipbob) - [Mintsoft 13](https://actionlake.com/connectors/mintsoft) - [ShipHero 12](https://actionlake.com/connectors/shiphero) - [Shippo 10](https://actionlake.com/connectors/shippo) - [Easyship 10](https://actionlake.com/connectors/easyship) Joins with, on shared entities - [SAP Business One 3](https://actionlake.com/connectors/sap-business-one) - [Odoo 3](https://actionlake.com/connectors/odoo) - [ERPNext (Frappe) 3](https://actionlake.com/connectors/erpnext-frappe) - [Square 3](https://actionlake.com/connectors/square) - [Cin7 Core 3](https://actionlake.com/connectors/cin7-core) - [eBay Sell APIs 3](https://actionlake.com/connectors/ebay-sell-apis) Browse - [All Commerce connectors](https://actionlake.com/connectors/category/commerce) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
