Hi all, We've been using Express Checkout with Billing Agreements/Reference Transactions since 2016. I just noticed that the Express Checkout integration method has been deprecated for some time, so I started looking into newer ways to integrate. It turns out that the billing agreement RESTful API endpoints have also been deprecated, so I'm not sure what the best approach is to continue to support our current methods of billing. What would be the best approach in our situation. Upgrade our integration to use the RESTful API and knowingly use a deprecated endpoint, or does the new(er) Subscriptions API provide what we need? Thanks!
