Hello, Everyone! Sincerely hope everyone is healthy.
I have developed a custom app on my development store.
The custom app is hosted on my localhost.
I have installed the custom app on the development store successfully and got the access token too.
Then I have created new php file called as index.php.
I think the index.php file would be default entry point of any shopify app. Right?
Anyway, after creating index.php, I have clicked the custom app in the Apps list of development store dashboard.
Then the web page shows "403 Forbidden"
Attached is the screenshot of the error page.
I have found the solution for one week by googling and analyzing code, but they were not helpful.
Please help me to solve this problem.
