The Merchants API groups individual seller locations into larger organizations, allowing them to operate as a single entity. Each merchant represents one organization or business that sells with Square and all team members of that business can coordinate on behalf of the merchant.
When a Square seller connects to your application with OAuth or a personal access token, your application receives an access token that is scoped to that merchant group. Use the Merchants API to retrieve core information about the organization connecting to your application, such as the language preferences, business name, country, and account status.
Some API tasks, such as managing orders or taking payments, are associated with a specific seller location using a location_id. Use the Locations API to access information about these locations.
Note
- The application developer account and seller account are separate Square accounts. Developers cannot perform any actions, such as taking payments, on behalf of sellers before the seller has granted the application developer permissions through OAuth. For more information, see OAuth API Overview.
- The
idof a particular merchant is only accessible through the Merchants API. It's not visible on the Seller Dashboard or Developer Dashboard.
In the Square data model, the access token (OAuth or PAT) used to connect your application to a Square seller is associated with a single merchant. Use this merchant's ID in the request URL for the RetrieveMerchant endpoint to access information about the merchant.
