I want to integrate paypal in my java web application. I saw that they offer many methods for this. But I want my visitors to stay on my site. My friend told me that Paypal offers a web service. But I can not find any documentation on the Paypal website. If anyone could help me, I would be very grateful. Please offer me relevant links to Paypal, where I can read and do my thing.
Secondly, my friend also told me that we need to specify a place for PayPal where my visitors will be redirected after payment is completed in PayPal. But I am confused. I work on localhost. How does Paypal find out about my localhost?
I already created my test account for the sandbox. What should be my next step. Please explain to me in detail. I don't know anything about Paypal. As soon as I created the Express Checkout demo application, where they give a simple Pay Now button and when you click on it, a basket appears, etc. But now I want my visitors to stay on the same site.
Thanks in advance:)
