How can I pay for the application?

Question

I have been programming for many years, and I have also done several professional software projects. I recently asked a friend to ask about the creation of an e-commerce site, but I had to abandon it because I had never worked on a web application that could pay. I might also need to write a web service based on a subscription in the future. My question is, how do I even start with billing? I never found a guide about this, and I hardly know how bank accounts work, since I do not manage my own (I have an excuse for this, since I am only 16).

I don’t know if the language depends on the language, but if these are the languages ​​that interest me, these are Python, C / C ++ and Java.

Answer 1

There are many ways to create e-commerce sites;

If you don’t have any experience and don’t want to get involved in something “complicated,” I would suggest going with a customizable web “storefront” posted by someone else, pre-integrated with credit card processing, etc. d. There are many options for these online. Just search google for the “web store”. Yahoo! even has the following service:

Going beyond that, it's pretty easy to integrate with someone like PayPal. They have all sorts of options from the simplest (use the link to send someone to your site with query string parameters to let paypal know what the user wants to buy):

Answer 3

Usually you will interact with a third party to conduct banking transactions. One of them that I worked with in the past is Authorize.Net, but there are many (PayPal is another quite popular one with a decent API).

In principle, the best approach is to do as little as possible and allow a third party to handle all the “hard” things (such as security, managing credit card information, etc.).
