Through Payment Service Providers
Use case
The solution can be integrated within some of the common PSPs (Payment Service Providers).
By Stripe Payment Element
Please refer to Stripe Payment Element.
This simplifies the user interface on merchant's web site, all the payment methods are displayed at the same place, in a similar way.
Merchant needs to add an externalPaymentMethodType.
