If your application is available at a standard http:// URL, you should use the default http:// port 80 for your application. Custom port numbers, ie. a port number other than 80, may not properly with Mxit for http:// endpoints.

If your application is available at an encrypted https:// URL, you should use the default https:// port 443 for your app. Again, a custom port number (ie. other than 443) may not properly with Mxit for https://endpoints.
