Default Payment back end setting - Admin

Hello All,
where is default payment shop back end setting in admin panel.

CoreShop or Pimcore Ecommerce Framework?

Pimcore E-commerce shop

there is no admin panel settings for that.

If no payment settings provided in shop backend then how to provide payment settings for the merchant information like (payapl-api-key, payapl-api-username,payapl-api-password).

We have need to integrate new payment module but I saw the admin panel settings, there is no payment relevant settings available in shop backend. How to enable / disable the payment in shop backend and integrate a new payment module. If any guide available for payment integration please suggest me…

I am waiting for your reply…

I don’t know how to do that with the e-commerce framework, but i am pretty sure there are docs for it somewhere
