OAuth 2.0 - IOS API V 2.0

Yes, you can certainly use that endpoint to get an OAuth 2 access token and then use the HTTP interface for API v2.

ok, thanks Gregory, another question if possible, i have problem with parameters for API v2, for example :

NSString *urlWithParams = @"https://api.dropboxapi.com/2/sharing/get_shared_links";

    NSURL *url = [NSURL URLWithString:urlWithParams];

   NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];    

    [request setHTTPMethod:@"POST"];

    [request addValue:[appDelegate apiAuthorizationHeader] forHTTPHeaderField:@"Authorization"];

    NSDictionary *parameters = @{@"path": @"};

    NSMutableString *parameterString = [NSMutableString string];

    for (NSString *key in [parameters allKeys]) {

        if ([parameterString length]) {

            [parameterString appendString:@"&"];

        }

        [parameterString appendFormat:@"%@=%@", key, parameters[key]];

    }

    if (parameterString) [request setHTTPBody:[parameterString dataUsingEncoding:NSUTF8StringEncoding]];    

    NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data,

...

the problem is :

NSDictionary *parameters = @{@"path": @"};

NSMutableString *parameterString = [NSMutableString string];

    for (NSString *key in [parameters allKeys]) {

        if ([parameterString length]) {

            [parameterString appendString:@"&"];

        }

        [parameterString appendFormat:@"%@=%@", key, parameters[key]];

    }

    if (parameterString) [request setHTTPBody:[parameterString dataUsingEncoding:NSUTF8StringEncoding]];    

the format is incorrect ... where is the problem ??

thanks

It looks like you're form encoding the parameter(s) that you send in the body, but the API actually just expects JSON:

https://www.dropbox.com/developers/documentation/http#documentation-sharing-get_shared_links

For example, in this case, the data you send up should just be:

"{"path": "}"

yes, mmm please, if possible, write small example in object-c ... 

i have tested with :

...

 NSString *urlWithParams = @"https://api.dropboxapi.com/2/sharing/get_shared_links";

    NSURL *url = [NSURL URLWithString:urlWithParams];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];

    [request setHTTPMethod:@"POST"];

    [request addValue:[appDelegate apiAuthorizationHeader:2] forHTTPHeaderField:@"Authorization"];

NSDictionary *parameters = @{@"path" : @"};

    NSError *error;

    NSData *postdata = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:&error];

    [request setHTTPBody:postdata];

    NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {

but too error 400 ...

What's the body of the error response? It should contain some more useful information.

no this is httpResponse :

<NSHTTPURLResponse: 0x7fa7438723f0> { URL: https://api.dropboxapi.com/2/sharing/get_shared_links } { status code: 400, headers {

    Connection = "keep-alive";

    "Content-Type" = "text/plain; charset=utf-8";

    Date = "Tue, 24 Nov 2015 19:15:03 GMT";

    Server = nginx;

    "Transfer-Encoding" = Identity;

    "X-Dropbox-Request-Id" = 998c7ed7b7368bf59b7753ce5ae43308;

} }

That only seems to be showing the status code and headers. What is the body of the response?

Error in call to API function "sharing/get_shared_links": Bad HTTP "Content-Type" header: "application/x-www-form-urlencoded".  Expecting one of "application/json", "application/json; charset=utf-8", "text/plain; charset=dropbox-cors-hack".

That seems to be it then. The API expects a "Content-Type" header of "application/json", but your code apparently sends up "application/x-www-form-urlencoded". Change that to "application/json" and try again.

ok, 

add :

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

and now it's ok ....

good work.
