Enhance the Facebook Login popup with personalized settings

When a user clicks, a popup is triggered:

FB.login(function () {
           // My CallBack
        }, { scope: 'email,user_birthday,user_location,user_hometown' });

This generates a Facebook login link with multiple parameters.

I desire to include an additional parameter of my own like UserHasClicked=1. However, when I attempted to add it to the scope 

{ scope: 'email,user_birthday,user_location,UserHasClicked=1' }

a message stating Scope Invalid was displayed.

What is the method to append my custom parameter to the generated FB link through the login() function?

Answer №1

Have you considered utilizing the callback function within the login method to achieve the desired behavior instead? It would be a more effective approach, allowing you to incorporate the necessary logic for when the userHasClicked.

FB.login(function () {
           userHasClicked = true
}, { scope: 'email,user_birthday,user_location,user_hometown' });

Answer №2

I'm unsure if this is what you're looking for, but it seems like you're interested in knowing whether or not a user has opened the login popup. To achieve that, you may consider implementing the following code within the callback function of your button/link/any relevant element:

document.getElementById('loginBtn').addEventListener('click', () => {
    const someNewParm = 1;

    FB.login(() => {
        //this particular section will execute when the user either cancels or authorizes the login
        console.log(someNewParam); //proceed with whatever action you intend to perform using this parameter after authentication
    }, {scope: 'email,user_birthday,...'});
});
