Hello again.
So there will be a few things you will need to research and this will start with the stripe documentation. You will need to look through how the say you can integrate the service. For example, is there an API?
After that we can look at how you would integrate into Wix through Velo. For example, if Stripe exposes an API that you can use then you can look through the documentation here (some linked above) for integrating 3rd party APIs
Finally, as far as integrating into a WixStore, that will depend on what you want to do and where. It may require a custom stores solution, but potentially not depending on where you are trying to put the functionality. With out of the box apps, there are some places you can extend the functionality and some that require a fully custom solution.
Again, I am definitely not an expert on that Stripe product but my general response here is yes, you can integrate 3rd party services. So it is potentially possible. Perhaps someone in the community here will have more insight/have worked with Stripe Connect.
