    private String accessToken;
    public BitlyIntegration() {
        this.accessToken = getAccessToken();
    }
    //Method for create shorten URL from Bitly
    public String createShortenURL(String url) {
        HttpRequest req = new HttpRequest();
        //'callout' is NamedCredential Label.
        req.setEndpoint('callout:Bitly/v3/shorten' + '?access_token=' + this.accessToken + '&longUrl=' + EncodingUtil.urlEncode(url, 'UTF-8') + '&format=txt');
        req.setMethod('GET');
        Http http = new Http();
        HttpResponse res = http.send(req);
        return res.getBody();
    }
    //Method for get access token from Bitly 
    private String getAccessToken() {
        HttpRequest req = new HttpRequest();
        //'callout' is NamedCredential Label.
        req.setEndpoint('callout:Bitly/oauth/access_token');
        req.setMethod('POST');
        req.setHeader('Content-Length', '0');
        Http http = new Http();
        HttpResponse res = http.send(req);
        return res.getBody();
    }
}
