Yes, this is the place for asking question about coding in Velo but in your last comment you mentioned you wanted a no-code solution.
If you are looking to interact with a 3rd party product you will need to do some research and see how they expose it to be integrated. For example, is there an API?
So, once you know how from the Stripe side they say to integrate you can look at the best way to accomplish that in Velo.
So, my first question is - how does Stripe state that you can integrate their product? The answer to that will drive how you can attempt this in Velo
