Thank you for your reply. About limit on product creation, maybe I was doing some mistake. I sorted out using your frontend https://www.sandbox.paypal.com/billing/plans signing in using the default business account credentials I found in the sandbox dashboard. About deleting a product, I accept the answer even if I don't understand the reason why. About billing plans list, I see that /v1/payments/billing-plans endpoint is deprecated. In any case I was looking for the list of all subscriptions but I'm not able to find anything in the new api https://developer.paypal.com/docs/subscriptions/full-integration/subscription-management/ Thank you Luca
