I have followed and done all the steps to setting webhook in local system using the bigcommerce documentation https://developer.bigcommerce.com/api-docs/getting-started/webhooks/setting-up-webhooks
It's working fine with local environment ngrok (It will work for only 8 hours)
But I need to know how to set the webhook in the server?
Do I need to purchase a separate server or can I set it in my theme directory? If so how to set it up? Please help.
