I have got a website using the facebook api.
I have got my test environment, where my web application is deployed, with url : preprod.mycompany.test (this is the url of my company)
I have got a current version of the web application already running on www.clienturl.test (this is the client url)
Can I ask facebook to review on my test url, and then once I deploy the new version on the client site, update the url of my facebook application ?
Does the review process start again if I change the web application url on the facebook application settings page?
Your question has been answered here: Facebook app review - Change platform URL
You can use a staging URL for the review and change to production post-review without the need to submit for again.
