Messenger Bot Webview not closing on IOS

Question

I have a webview in my bot. I have the following JS code to close it:

complete: function (data) {
                    MessengerExtensions.requestCloseBrowser(function success() {
                        }, function error(err) {
                            window.close()
                        });
                    console.log("post success");
                }

The webview is being closed on ANDROID and WEB But NOT on IOS.

Any help would be appreciated.

Answer 1

So apparently my problem was a mistake which led to a misunderstanding of the problem.

I didn't add messenger_extensions: true and didn't whitelist my domain. Due to that the MessengerExtensions call failed, and always got to the fallback which was window.close() - which works on WEB and Android, but not on IOS - hence I thought that all works but IOS.

After adding messenger_extensions: true and whitelisting the domain all worked out.
