Which domain registrar has a convenient reseller account?

Question

Domain name market

It is necessary to register domains for clients, give them a discount and allow domain renewal on my site. In general, I admit that my clients would renew the domain themselves on the registrar's website, but then they should still have a discount.
I tried r01, but the API is incomprehensible there help.r01.ru/partner/api.html and technical support is unrealistically disgusting.
What does he use for his clients?

Answer 1

To register ru/su/rf use Webnames. Many here will say Reg.ru, but before working with them, google topics about them with searchengines (they pull customers to you). I don't like Naunet, the RuCenter is also difficult.
