Integrate 3rd party payment system using their SDK


I need to use payment system ECOMMPAY (Stripe doesn't work in some countries) in my app with Xano backend.

They provide various SDK - PHP, Java, Javascript etc.

Is it possible to use SDK in Xano for the fastest integration? is it JavaScript as Lambda or PHP is better?

Or should I build Xano API with 3rd party only from scratch to use integration?
