I'm developing an app for Shopify. Currently under development stage. Until now, I have successfully managed to authorise the app and then redirect it back to admin page using the Embedded App SDK. However, when I return to the admin page, it gives me an error saying
Request origin cannot be verified.
The console shows
Failed to load resource: the server responded with a status of 403 (Forbidden) The URL in the console is something like this
fdfdfdfdfdfdfdfdfddfdfdfdfdf are just random characters that I've replaced instead of a hash.
I'm assuming it was you asking your question here as well where it was answered: https://stackoverflow.com/questions/47553382/request-origin-cannot-be-verified-shopify.
Let me know if you have your answer!
add your app url in allowed redirection urls or in the whitelisted url like this.
mine was also not working at first but then i tried like this at it worked.also check in your shopify store that you have already installed the app or not.if yes simply refresh your page and re-click on shopify app section then select your installed test app from there.
