Premiere UXP Plugin - Subscription for services?

I am creating a Premiere UXP Plugin.
It will be free for users to download, but require a subscription in or to purchase "credit packs" in order to use the plugin's features. A given feature will cost X amount of credits.

Can I charge subscriptions via Stripe, or does Adobe require me to use their own payment processor?
Are there any rev-shares with Adobe that need to be handled?

Any other advice around this topic would be helpful - thanks!
