+Calls to the Marketplace API must be authenticated using Mona’s external managed identity. For use in Logic Apps, Mona's external managed identity must be added so that it can be selected and used: Logic App->Settings->Identity->User assigned->mona-external-id-[...].
 
 To locate the managed identity:
 
 - Go to the Mona admin center.
 - Open the **This Mona deployment** tab.
 - Click **Managed external identity**.
 
-This will direct you to the Azure portal, where you can manage the identity. You can use this identity in [Logic Apps](https://learn.microsoft.com/azure/logic-apps/authenticate-with-managed-identity?tabs=consumption#authenticate-access-with-managed-identity), [Azure Functions](https://learn.microsoft.com/azure/azure-functions/functions-identity-based-connections-tutorial), or [other managed identity options](https://learn.microsoft.com/entra/identity/managed-identities-azure-resources/managed-identities-status). Use the managed identity to [obtain a token for the Marketplace API](https://learn.microsoft.com/partner-center/marketplace-offers/partner-center-portal/pc-saas-registration#how-to-get-the-publishers-authorization-token) and [activate the subscription](https://learn.microsoft.com/partner-center/marketplace-offers/partner-center-portal/pc-saas-fulfillment-subscription-api#activate-a-subscription).
