I want to sell some yearly and monthly accounts on my project, how can I integrate my back getaway?
Hi Masoud. I think what you are after are payment gateways. In the US these are people like Stripe, Square, and several others. I don’t know what they might be in your region, but a search for Payment Gateway or Merchant Services would get you some possibilities. Once you know some of the names you can search in here and on Git to see if anyone has written an integration for any of these services. After that the process gets easier. Set your Items up as a Subscription and you should be ready to go.
Sorry I can’t offer more help. Hopefully you have a direction to pursue.
