Handling hundreds of subdomains

I've got an issue and I can't get a hold of Apple through an official TSI. I am hoping someone can help me out here. We have a massive application where our customers have their own unique subdomain. We'd like to offer Apple Pay, but I can see handling certs for every subdomain, in 3 different environments, being a maintenance nightmare.


Does anyone know if Apple can do wildcard certs or if you can just have one cert for one domain and it handle ALL subdomains?

Did you ever figure this out? I'm wondering the same thing.
