title: Shopify App - define url to redirect when app is selected form app list of a shop
body: <p>I'm new to shopify app development and trying to build a shopify app with node and followed this post <a href="https://help.shopify.com/api/tutorials/building-node-app" rel="nofollow noreferrer">here</a>. Everything worked as explained, but I have things to get clarified, may be very basic things.</p>
  
  <p>My question is where to specify the link that's directed when shop owner select my app from the installed apps list of the shop?</p>
  
  <p>As I understood from the post above <code>App URL</code> given in the App info section of the app is used for installation process and from there it's redirected to one of the <code>Whitelisted redirection URL(s)</code> as defined in the app for <code>HMAC</code> validation and exchanging a permanent access token to access the shops' admin API later.</p>
  
  <p>Now Once my test-app is installed to a shop and when the app is selected from the installed apps list, the request again goes to the <code>App URL</code> and get redirected to <code>callback URL</code> generating a new access token. If this is how it is supposed to be, why it's called a permanent access token and need to be stored? If this not how it should be how to specify a url to direct when the app is selected from the installed app list?</p>
  
  <p><strong>In Short</strong></p>
  
  <p>where to define the url to direct when a shop admin select the app from is installed apps section of the shop like shown below.</p>
