Trying to install test app to test store but doesn't generate a code in the url

Shopify Apps

Topic summary

A developer is encountering an issue while installing a test app to handle orders and client information via their API.

The Problem:

  • When clicking “Install App,” they are redirected to their Redirect URL instead of the App URL
  • The redirect includes parameters (hmac, host, shop, timestamp) but is missing the authorization code parameter needed to complete OAuth

Key Question:

  • The developer is unsure whether they need to create another redirect URL or if private apps work differently than public apps in the installation flow

Status: The issue remains unresolved with no responses yet. The missing authorization code prevents the app from completing the OAuth handshake required for API access.

So in my Redirect url i get the hmac, host, shop and timestamp but i have no code parameter, do i have to make another redirection url or how does this works? Because it seems that private apps works different than public apps

If i try to install the app via
[myurl…]?
