Integrating Paypal with .Net Core 3

I have a .Net Core 3 project and I want to integrate Paypal.

In past projects I was using Paypal package, but now I was reading their documentation and they recommend to use version 2 of their API. (Previously I was using version 1 with Paypal SDK). If I go to the nuget.com and check the Paypal package I see that version 2 of this package is still rc:

Version     Downloads   Last updated        
2.0.0-rc2   143,570     2018-04-12T18:17:40Z

Now it has been almost 2 years in this, so it doesn't look promising. If I check their docs again I find that they recommend using following package: PayPalCheckoutSdk. Link to their docs. If I try to copy-paste an exampe it doesn't even compile (mainly due to some properties renamed). This really doesn't give a lot of confidence in using this package at all. My last resort would be just to call paypal API directly without using their provided SDK.

What is the best way to integrate paypal with my server running on .Net Core 3.1?

Call the v2/orders API directly.

Server-side create: https://developer.paypal.com/docs/api/orders/v2/#orders_create

Server-side capture: https://developer.paypal.com/docs/api/orders/v2/#orders_capture

Follow the PayPal Checkout integration guide and make 2 routes on your server, one for the 'Create Order' and one for 'Capture Order' (see the optional step 5 in 'Add and modify the code'). Both of these routes should return only JSON data (no HTML or text). Inside the 2nd route, when the capture API is successful you should store its resulting payment details in your database (particularly purchase_units[0].payments.captures[0].id, which is the PayPal transaction ID) and perform any necessary business logic (such as sending confirmation emails or reserving product) immediately before forwarding your return JSON to the frontend caller.

Pair those 2 routes with the frontend approval flow: https://developer.paypal.com/demo/checkout/#/pattern/server
