Bigcommerce应用程序 - 如何更改Auth回调URL

I am new to Bigcommerce app

From the sample github, https://github.com/bigcommerce/hello-world-app-php-silex

How to give the

Auth Callback URL: https://<app hostname>/bigcommerce/callback

Load Callback URL: https://<app hostname>/bigcommerce/load

Uninstall Callback URL: https://<app hostname>/bigcommerce/uninstall

where, <app hostname> represent http://localhost/repo/hello-world-app-php-silex (or)

http://XXX.mybigcommerce.com/hello-world-app-php-silex

In the point 5, they mentioned as "Restart the software or the entire host as needed to set the environment variables." How to restart ?

When you add the Auth Call back URL's to your .env file as per the example. You need to restart the web server. That is the point mentioned on the GitHub page.

 BC_AUTH_SERVICE=https://login.bigcommerce.com
 BC_CLIENT_ID=<contents of Client ID field>
 BC_CLIENT_SECRET=<contents of Client Secret field>
 BC_CALLBACK_URL=<URL TO YOUR AUTH CALLBACK ENDPOINT>

Also, note that the BC_CALLBACK_URL has to be the same you setup in developer portal when you configure the app.
