Hi Rohit,

You can use the new feature provided by Salesforce for the same which is known as Files Connect.
Please refer to the documentation for the same. Hope this helps.

Please mark this as solved if it's resolved.

Hi Rohit,

You need to first authenticate the credentials from the link https://console.developers.google.com/project
Follow the link for the step to create the project and credentials -- credentials https://help.salesforce.com/articleView?id=000239696&type=1

The second Step you need to create one visual force page, I have added the VF page 
<apex:page controller="GoogleDriveController">
    .error {
    font-style: italic;
    font-size: 15px;
    font-weight: bold;
    text-align: center;
    color: green;
    .myClass {
    color: black !important;
    background: #87ceeb !important;
    width: 300px;
    font-size: 20px !important;
    height: 35px;
        <apex:form style="margin-top:5%;margin-left:5%;width:60%">
        <apex:pageblock >
            <apex:commandbutton styleClass="myClass" onclick="this.value = 'Authenticating....'" action="{!DriveAuth}" value="Google Drive Authentication">
            <apex:inputfile value="{!file}" contentType="{!filetype}" filename="{!filename}" />
            <apex:commandButton styleClass="myClass" onclick="this.value = 'Uploading...'" value="Upload file" action="{!UploadFile}" />
            <apex:messages styleClass="error" />

The third step is you need to create the apex-class and assign the client id and client secret which you will get from google API credentials,
I have attached the apex-class also after following this step you will be authenticated and your file will be uploaded from salesforce to google drive.
public class GoogleDriveController {
    private String code;
    public boolean val {get;set;}
    public blob file { get;set;}
    public String filetype { get;set;}
    public String filename {get;set;}
    private string key = 'Client_id';
    private string secret = 'Client_secret';
    private string redirect_uri = 'https://teqtrailhead-dev-ed--c.ap5.visual.force.com/apex/GoogleDrivePage';
    private String accesstoken;
    private Integer expiresIn;
    private String tokentype;
    public GoogleDriveController() {
        code = ApexPages.currentPage().getParameters().get('code');
        //Get the access token once we have code
        if (code != '' && code != null) {
            System.debug(' code__ ' + code);

    public PageReference DriveAuth() {
        PageReference pg = new PageReference(GoogleDriveAuthUri(key, redirect_uri));
        return pg;

    public String GoogleDriveAuthUri(String Clientkey, String redirect_uri) {
        String key = EncodingUtil.urlEncode(Clientkey, 'UTF-8');
        String uri = EncodingUtil.urlEncode(redirect_uri, 'UTF-8');
        String authuri = '';
        authuri = 'https://accounts.google.com/o/oauth2/v2/auth?'+
        'redirect_uri=' +uri+ 
        return authuri;
    public void UploadFile() {
        String boundary = '----------9889464542212';
        String delimiter = '\r\n--' + boundary + '\r\n';
        String close_delim = '\r\n--' + boundary + '--';
        String bodyEncoded = EncodingUtil.base64Encode(file);
        String body = delimiter + 'Content-Type: application/json\r\n\r\n' + '{ "title" : "' + filename + '",' + ' "mimeType" : "' + filetype + '" }' + delimiter + 'Content-Type: ' + filetype + '\r\n' + 'Content-Transfer-Encoding: base64\r\n' + '\r\n' + bodyEncoded + close_delim;
        Http http = new Http();
        HttpRequest req = new HttpRequest();
        req.setHeader('Authorization', 'Bearer ' + accessToken);
        req.setHeader('Content-Type', 'multipart/mixed; boundary="' + boundary + '"');
        req.setHeader('Content-length', String.valueOf(body.length()));
        req.setTimeout(60 * 1000);
        HttpResponse resp = http.send(req);
        file = null;
        filetype = '';
        filename = '';

    public void AccessToken() {
        //Getting access token from google
        HttpRequest req = new HttpRequest();
        req.setHeader('content-type', 'application/x-www-form-urlencoded');
        String messageBody = 'code=' + code + '&client_id=' + key + '&client_secret=' + secret + '&redirect_uri=' + redirect_uri + '&grant_type=authorization_code';

        req.setHeader('Content-length', String.valueOf(messageBody.length()));
        req.setTimeout(60 * 1000);

        Http h = new Http();
        String resp;
        HttpResponse res = h.send(req);
        resp = res.getBody();
        JSONParser parser = JSON.createParser(resp);
        while (parser.nextToken() != null) {
            if ((parser.getCurrentToken() == JSONToken.FIELD_NAME)) {
                String fieldName = parser.getText();
                if (fieldName == 'access_token') {
                    accesstoken = parser.getText();
                } else if (fieldName == 'expires_in') {
                    expiresIn = parser.getIntegerValue();
                } else if (fieldname == 'token_type') {
                    tokentype = parser.getText();
        System.debug(' You can parse the response to get the access token ::: ' + resp);

Feel free to ask if you need further clarification.

Mark, it as best answers if you like it.
