I was wondering what programming languages make applications like Ali Dropship work? I have a hunch it might be XML, JSON or REST but I wanted to attempt to make something similar as a web app.
I need my web app to:
- Send information like addresses to a third party website
- Process payments so that third-party website
- Send receipts and confirmations to customers using the third party website.
I am willing to accept APIs or software suggestions that will allow me to create something like this. However, I would prefer just knowing the coding languages.
