title: How to set up a PayPal sandbox "Seller" account, a "Buyer" account and an Application Tutorial
body: <p>I am trying to set up a Web site which is using PayPal. Unfortunately the PayPal developer site/concept is heavily changed, so all tutorials I found are seem to be useless. For example this (very good) <a href="http://www.youtube.com/watch?v=CEhUOGW9nLc">youtube tutorial</a> which is very clear is using not existing pages and functions...</p>
  
  <p>So please try to help me only with up to date information/tutorial.</p>
  
  <p>Please note my questions is not about using API, it is about how to set up an app, and a testing sandbox configuration from the ground.</p>
  
  <p>1) As far as I understand I must have a <em>real</em> PayPal account because dev site uses PayPal account for logon (new). Logged in with this account then I can create sandbox accounts. However I would like to create a "Seller" sandbox account and a "Buyer" sandbox account. (missed I something?) Using the new developer site it is not possible. I can create only one kind of sandbox account. In the referenced video there are two types of sandbox accounts: "seller" and "buyer" in the preconfigured accounts. Or "Seller" simply means Business account?</p>
  
  <p>2) I must have an application id to use the API. Note: I inherited a working legacy code which is using the classic API, so no REST please. In the video (old PayPal dev site) there is a left side menu "API and Payment Card credentials" In the new PayPal dev site no such thing. Instead there is a "My Apps". </p>
  
  <p>I've tried to set up an application. It approved automatically. In its metadata I see a live and a sandbox app id. </p>
  
  <p>What is not clear: To what account is associated this newly created app? I've created it logged in with my real paypal credentials. 
  More: ??? When filling the app creation form there was an input field titled: "Supply Test Account Name and Password". First of all how can I type the name <em>and</em> a password to <em>one</em> input field? Secondly What is it? Maybe if I use this app with its sandbox app id then this account will be the Seller (got the money) and if I change the app id to the live one associated this app, then my real PayPal account got the money? </p>
  
  <p>However my goal was to completely simulate the payment process so</p>
  
  <p>1) Create a Seller sandbox account (got API credentials)
  2) Associate an application to that Seller account, and get the app id.
  3) Create a buyer sandbox account</p>
  
  <p>4a) Configure my web site with Seller API credentials and sandbox app id
  4b) Orchestrate a buy process using my website, PayPal API and the 2 sandbox account</p>
  
  <p>5) Check the Seller and Buyer sandbox account's transactions.</p>
  
  <p>Thanks in advance</p>
