Facebook Login error

https://api.backendless.com safari cannot open page because the address is invalid

This URL is used only by Backendless API clients - for Backendless site you should use http://backendless.com

After changing i get this

Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App’s settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App’s domains.


Using Backendless UserService loginWithFacebookSDK: method needs the additional setting in Info.plist file of your project (see for my app):

I check the info plist everything look the same

Is this correct url input ?

It works fine for me, and you?

No, it should be https://api.backendless.com as described here:


Same problem here guys. Im using https://api.backendless.com . Everything goes well, I get to the FB window asking me if I give my app to access my info, then Safari goes to https://api.backendless.com and I get a pop up saying :“safari cannot open page because the address is invalid”

Could you please attach screenshots of the facebook app configuration page and one from backendless console (Manage > Social Settings). For security purposes you are welcome to email the screenshots to support@backendless.com.


See this comment. Hope it will be helpful for you.

Also you can investigate a whole this thread.


I’m facing the exact same issues. User is registered in DB but that window still appears. Setting the App id in the Plist also didnt work.
