Does unity support payment gateways?

I am making a game in which the players have an ingame currency, for example gems, and I want to allow the players to redeem the gems for real money and the only way to do that, that au am aware of, is through payment gateways
Does unity support payment gateways?
Or does it have another solution to this problem?

 

Look into Unity In-App-Purchases (IAP): https://docs.unity3d.com/Manual/UnityIAP.html

 

Thank you so much but I did research on IAP purchase in unity and it doesn't exactly offer me what I'm looking for
Like IAP is for allowing players to pay for certain conveniences in the game (using real money) whereas I want to pay the players of the game in real money so money would have to be transferred from an account( mine ) to the players and that's why I though payment gateways would be best
Or are you suggesting that It can be done using IAP in unity?
Is it that I have to do some more research on how to achieve that
If so would you please be so kind as to point me to the places where I can begin my research, if you don't mind
Thank you for your time
