Hi,I had done the integration earlier with facebook. But now those pages
are not opening because of some security updates done by Facebook.I
think you need to give the Terms and conditions, Private policy URLs in
the respective fields which are mandatory, and you need to give
permissions in the developers account page. And you need to add the
products to your page.And in the Advanced settings add the valid
callback uri's. The following links may help
you.https://stackoverflow.com/questions/37255...
