Hi!
We are integrating with a dropshipper called Kaerwell.
They need the Merchant ID for our account so that they can hook our Square website (not POS) with their Order Management System
Where can I find the Merchant ID?

The Merchant ID for your Square account is not directly visible on the Seller Dashboard or Developer Dashboard. However, you can retrieve it by using the Square Merchants API. 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. You can use the Merchants API to retrieve core information about the organization connecting to your application, such as the business name, country, and account status. The ID of a particular merchant is only accessible through the Merchants API. You can request the specific merchant associated with your account’s access tokens by calling RetrieveMerchant using ‘me’ in place of the merchant ID.
