OAuth Client redirect url for tenant specific subdomain applications

We are using the Zendesk OAuth client functionality for our SaaS application, which in the future we want to convert to a global OAuth client.

Our application has custom subdomains for different tenants, e.g.

Tenant A - https://tenantA.awesomeapp.com
Tenant B - https://tenantB.awesomeapp.com

Right now this gives me issues when specifying the Redirect URLs in the OAuth client settings.

I tried to specify to allow a wildcard subdomain, e.g. like this:
https://*.awesomeapp.com/zendesk/oauth/redirect

But that does not work.

My questions are:

• Would we still have this problem if we globalize our OAuth client to the marketplace?
• If yes, how would we solve this problem?
