Link a connected account to a customer
Links the customer to an account in an external system by recording the integration and the account’s identifier in that system. This records the mapping only: it does not create anything in the external system and does not trigger a sync of any data in either direction. The id path parameter accepts the Alguna account ID, a customer alias, or an existing connected-account external ID.
