I've been stuck with this for a few days. I know that it's probably the most asked question about shopify Oauth.
To begin with, I got an shopify app to work with, the client asked me to make some modifications and I am facing issues with local environment setup.
I am using Ngrok for tunneling my connections.
Here is the redirect_uri parameter:
&redirect_uri=https%3A%2F%2Ff7311e59.ngrok.io%2Fauth
and full request url:
https://{shop.domain}.com/admin/oauth/authorize?client_id=eb5bba2f0a8474bad5fd687e055056af&scope=read_products,write_products,read_themes,write_themes&redirect_uri=https%3A%2F%2Ff7311e59.ngrok.io%2Fauth
and here are all whitelisted redirection URL's in app settings
https://f7311e59.ngrok.io/auth
https://f7311e59.ngrok.io/auth/
http://f7311e59.ngrok.io/auth
http://f7311e59.ngrok.io/auth/
Hopefully I'm not blind, because i don't see any mismatches in those urls
&redirect_uri=https%3A%2F%2Ff7311e59.ngrok.io%2Fauth
https://f7311e59.ngrok.io/auth
I am wondering if this could be some specific aplication architecture issue, also I am new at shopify app's developement so maybe there's something I've missed. Thanks
