How use Payment Gateway in iran

I have a website with Iranian users.
I now have trouble selling my services to them and getting paid.
I do not know how to receive money from Iranian users.
PayPal is under sanctions in Iran.

Can we use a company like Ryan Pay to get a payment gateway?

What solution do you suggest?

Thankful

I just did a quick Google search, which found Yekpay, AllPays, BTTPay, Mahcard and others. I have no experience with any of these, so I wouldn’t know what to suggest.
