Good Morning,

I'm integrating Salesforce and Twitter. I'm getting an error {"errors":[{"code":215,"message":"Bad Authentication data."}]}

https://developer.twitter.com/en/docs/twitter-api/v1/tweets/post-and-engage/api-reference/post-favorites-create

Please check code once

public class TwitterController {    
    
    public static String generateOathNonce(){
        Blob blobKey = crypto.generateAesKey(256);
        String key = EncodingUtil.convertToHex(blobKey);
        String oathNonce = EncodingUtil.base64Encode(Blob.valueOf(key));
        oathNonce = oathNonce.replaceAll('[^a-zA-Z0-9]+',''+integer.valueOf(math.random() * 10));
        oathNonce = oathNonce.substring(0,42);
        return oathNonce;
    }
    
    public static long generateTimeStamp(){
        long timestamp = datetime.now().getTime(); 
        timestamp = timestamp / 1000;
        return timestamp;
    }
}

============================================

public class TwitterTweetsCtrl {
public Static void createFavorites(){
        String accessToken = TwitterController.retrieveAccessToken();
        Twitter_API_Settings__c twitter = [SELECT Id, API_Key__c, API_Secret_Key__c, Access_Token__c, Access_Token_Secret__c

        HttpRequest req = new HttpRequest();

    }
}

please help me,
