I support a web application that is a multi-tenant application.  My clients each maintain their own authorize.net account, and provide my application with their transaction keys, and I am able to collect payment information from my application's users and process them through their authorize.net accounts.

I'm looking at integrating my web application with ApplePay, and it looks like it's done on an account-by-account basis.  I have successfully tested this in the sandbox environment with a single authorize.net account.  However, when I went to test with a second authorize.net account, the apple developer area made me invalidate the initial Apple Pay Payment Processing certificate in order to work with the second.  Currently, the second account is working, but when I make requests to authorize.net to process a payment for the first account, I'm getting the following error: "There was an error processing the payment data. Invalid ownership."

I suppose this makes sense since I had to invalidate the first certificate in order to activate the second one.

But it leads me to ask: does authorize.net have a mechanism to support my situation?  I would like to set up Apple Pay for multiple customers.
