API Paypal Rest vs Classic Sdk

Question

I am working with PayPal for the first time. I have a product and I want to integrate PayPal with it.

I want to perform the following tasks:

• A client comes to my site and selects a plan, which is a monthly recurring plan.
• Then the client is redirected to Paypal for payment.
• Customer makes payment.
• Return to the main page.

I have looked at the PayPal documentation and I have the following questions.

• That I should use the REST API or Classic Sdk, because I want to create a repeating profile, work with EXPRESS-CHECKOUT and REFERENCE TRANSACTIONS.
• I have clients all over the world, and the documentation states that for customers in Germany and China I must use the REFERENCE OPERATION.
• Some where the Merchant SDK documentation states that the classic API will be deprecated is a good approach to using the Classic SDK
• I also wanted to track the transactions (payments) made by the user so that I could show him the amount that is deducted every month in his profile.

Please offer a possible solution to my problem.

Thanks in advance.
