Please help me regarding integration between dropbox and salesforce ,

This Below link very useful to me : http://forceguru.blogspot.in/2014/05/dropbox-authentication-in-salesforce.html

I want to get user details from dropbox and display it in salesforce.

Another requirement is, upload files from salesforce and upload it in dropbox . and get the files or images from dropbox and display it in salesforce....

I have access token ,api key, api secret all things , but I don't know how pass request and how to get response as user details.

In below Code ... in system debug I m getting

{ access_token":"krCeDZGxqoAAAAAAAAAg9ejz6i3bsgPfCmvpvZF1pR0cRH_u-NhQ_IjtVeR9Gwa", "token_type": "bearer", "uid": "328256643"}

But in system.debug of Account Information, I m getting following error- Account Information ::

{"error": "OAuth 2 \"Authorization\" header is not well-formed."}

Below is Apex Class:

public class DropboxController

    //Fetched from URL
    String code ;
    String accesstoken;
    public DropboxController()
        code = ApexPages.currentPage().getParameters().get('code') ;
        //Get the access token once we have code
        if(code != '' && code != null)
           AccessToken() ;


    public PageReference DropAuth()
        PageReference pg = new PageReference('https://www.dropbox.com/1/oauth2/authorize?response_type=code&client_id=nw7mfi19tfaxak8&redirect_uri=https://c.ap2.visual.force.com/apex/Dropbox&state=Mytesting') ;
        return pg ;

    public void AccessToken()
        //Getting access token from dropbox
        String tokenuri = 'https://api.dropbox.com/1/oauth2/token?grant_type=authorization_code&code='+code+'&redirect_uri=https://c.ap2.visual.force.com/apex/Dropbox'; 
        HttpRequest req = new HttpRequest();

        Blob headerValue = Blob.valueOf('nw7mfi19tfaxak8' + ':' + '9ek5zgp4hbxkjjq');
        String authorizationHeader = 'BASIC ' + EncodingUtil.base64Encode(headerValue);
        req.setHeader('Authorization', authorizationHeader);
        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();
        system.debug('accessToken==>'+accessToken );
        System.debug(' You can parse the response to get the access token ::: ' + resp);

        string token = 'https://api.dropbox.com/1/account/info';
        HttpRequest r = new HttpRequest();
        r.setHeader('Authorization','Bearer' +accesstoken);
        Http h1 = new Http();
        HttpResponse res1 = h1.send(r);
        string resp1 = res1.getBody();

        System.debug(' Account Information :: ' + resp1);

As I am new to integration any help will be grateful...


  • You're missing a space after Bearer on this line: r.setHeader('Authorization','Bearer' +accesstoken);

I see two problems regarding authorization.

  1. For basic level authorization, the keyword is Basic not BASIC. Its case sensitive.

  2. For any type of authorization a space is required between keyword and param. So a space is required after Bearer.

Hope it helps.
