Get long live access token from Facebook

There is a way to extend this to 60 days. described here: https://developers.facebook.com/docs/roadmap/completed-changes/offline-access-removal/ under Scenario 4: Client-side OAuth and Extending Access_Token Expiration Time through New Endpoint

Edit: In order to extend the access token you need to make the following request with your short lived access token:

https://graph.facebook.com/oauth/access_token?             
    client_id=APP_ID&
    client_secret=APP_SECRET&
    grant_type=fb_exchange_token&
    fb_exchange_token=EXISTING_ACCESS_TOKEN 

Due to a bug in Facebook, some users will have to unauthorize the app before Facebook will issue the long-lived tokens.

I just made a Facebook Graph API call using 'axios'. You can find the client_id and client_secret from your App Dashboard.

getLongLiveToken = () => {
    window.FB.getLoginStatus(function(response) {
        if (response.status === 'connected') {
            let userAccessToken = response.authResponse.accessToken;
            axios.get(`https://graph.facebook.com/oauth/access_token?client_id=${clientId}&client_secret=${clientSecret}&grant_type=fb_exchange_token&fb_exchange_token=${userAccessToken}`)
            .then((response) => {
                console.log("Long Live Access Token");
                console.log(response.data.access_token);
             });
           }
       });
    }
<button onClick={ () => this.getLongLiveToken() } >Long Live Token</button>

add function to the javascript with following details: i hope it's works for you.

function getLongLiveToken(data){

        FB.api('oauth/access_token', {
            client_id: data.client_id, // FB_APP_ID
            client_secret: data.secret, // FB_APP_SECRET
            grant_type: 'fb_exchange_token',
            fb_exchange_token: data.access_token // USER_TOKEN
        }, function (res) {
            if(!res || res.error) {
                console.log(!res ? 'error occurred' : res.error);
            }else{
                var accessToken = res.access_token;
                if(typeof accessToken != 'undefined'){
                }
            }
        });
    }
