Thanks for reply . But i am using api funtion already to get files and folder by api functions of a particular account by api acess token. But now the issue is that i want to get all the files and folder of login user( not from a particular account on which app is created ) Is their any funtionallity that i can get this by user login id or some thing else

Richard P.

You need to get them to link your app to their Dropbox account, and then use the token that process gives you.

As I said, read the documentation and the example apps.

i am using oAuth1 to login a user. Now after login i am getting access token of a user. But when i am trying to fetch all files and folders using v2 version by https://api.dropboxapi.com/2/files/list_folder using this access_token its shows a error . my response after login is

Array
(
    [oauth_token_secret] => <redacted>
    [oauth_token] => 0z8UB9b6JHyfUqBc
    [access_token_secret] => <redacted>
    [access_token] => 2oez4dz7r9w4xmlf
)



Also can i use oauth 1 for v2 version

Greg-DB

API v2 only supports OAuth 2, not OAuth 1, so you won't be able to use an OAuth 1 access token with OAuth 2.

The OAuth 2 endpoints are documented here:

https://www.dropbox.com/developers/documentation/http/documentation#authorization

(If you need to, you can use existing OAuth 1 tokens to get OAuth 2 tokens using /1/oauth2/token_from_oauth1.)

Deepika G.1

can you please tell me the parameter for https://api.dropboxapi.com/1/oauth2/token_from_oauth1 url . how can i pass the above access token to this to convert oauth1 access token to oauth2 access token . i am using below code

$ch = curl_init();
                       $postData = array(access_token => "32uqesryirha3ubf");
                        curl_setopt_array($ch, array(
                            CURLOPT_URL => 'https://api.dropboxapi.com/1/oauth2/token_from_oauth1',
                            CURLOPT_RETURNTRANSFER => true,
                            CURLOPT_POST => true,
                            CURLOPT_CUSTOMREQUEST => "POST",
                            CURLOPT_POSTFIELDS => json_encode($postData),
                            CURLOPT_HTTPHEADER => array('Content-Type:application/json'),
                            CURLOPT_SSL_VERIFYPEER => false
                        ));
                        echo $output = curl_exec($ch);
                        curl_close($ch);

Greg-DB

That endpoint requires OAuth 1 signing. For example, see step 4 in this blog post:

Hey Gregory

I have a query regarding download api. I am trying to download files by curl thorugh api.https://content.dropboxapi.com/2/files/download. But when am trying to send a curl req by sending below code it return nothing.

$ch = curl_init();
        $postData = array('path' => $folder);
        $data = json_encode($postData);
        curl_setopt_array($ch, array(
            CURLOPT_URL => 'https://content.dropboxapi.com/2/files/download',
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_POST => true,
            CURLOPT_CUSTOMREQUEST => "POST",
            CURLOPT_HTTPHEADER => array('Content-Type: ', 'Authorization: Bearer ' . $key, 'Dropbox-API-Arg:' . $data),
            CURLOPT_SSL_VERIFYPEER => false
        ));
        echo $output = curl_exec($ch);
        curl_close($ch);

where $folder = /deepikag4@chetu.com/newTask.xlsx

Can you please help me out

Steve M.

What do you mean by "it returns nothing"?

This part looks wrong:

'Content-Type: ', 'Authorization: Bearer ' . $key

But in general, the API returns pretty clear error messages that tell you what is wrong with a request, so make sure you're able to read the HTTP response bodies even when an error occurs.

Deepika G.1

Now am using

CURLOPT_HTTPHEADER => array( 'Authorization: Bearer ' . $key, 'Dropbox-API-Arg:' . $data),

but it giving me below error.

Error in call to API function "files/download": You provided a non-empty HTTP "Content-Type" header ("application/x-www-form-urlencoded"). This API function requires that the header be missing or empty.

Can you please tell me what parameter should i pass to get response

Steve M.

Sorry, I think I steered you wrong. Your Content-Type header was fine... here's code that's working for me:

$accessToken = '<REDACTED>';

$ch = curl_init();
$data = json_encode(array('path' => '/test.txt'));
curl_setopt_array($ch, array(
    CURLOPT_URL => 'https://content.dropboxapi.com/2/files/download',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => array("Content-Type:", "Authorization: Bearer $accessToken", "Dropbox-API-Arg: $data"),
));
$output = curl_exec($ch);
curl_close($ch);
echo $output;

Steve M.

An alternative (drop both CURLOPT_POST and the Content-Type header):

curl_setopt_array($ch, array(
    CURLOPT_URL => 'https://content.dropboxapi.com/2/files/download',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_HTTPHEADER => array("Authorization: Bearer $accessToken", "Dropbox-API-Arg: $data"),
));

Deepika G.1

Now am using above code. Error is removed now but its not returning any response.

Greg-DB

If you're not getting an error, the response should be the file content. Is it possible the file is 0 bytes? You can check on the Dropbox web site.
