We are developing an app for our client and want to integrate App Pay in our app through auth.net account. The client is a multi-location restaurant and each location already has it's own auth.net account set up.
However, when we publish this app to the app store, it will be under our developer's account not the client's developer account (as they don't want to pay developer fee&it's hard for us to manage). Question is, can we apply the merchant ID for each location in our apple developer account and use that to integrate into our app? By doing so would the transaction still go through client's auth.net account?
