Third-party payments (MBway)

Hi community!

I’m a designer based in Portugal and I’m looking to create an ecommerce website for my client (I still haven’t started the project).

However one of the main payment methods used in Portugal (MBway) isn’t built-in on Webflow.

For example, Ifthenpay is one of the main providers for this service and they offer some documentation but from what I understand they say it needs to be developed from scratch if the platform doesn’t support this.

Does anyone know if there’s a way to add a third-party payment option like this one while keeping Webflow’s ecommerce and checkout features?

Would really appreciate if someone could help me out here.
Thanks!
