Dropbox - Error: StatusCode=400

[JorgeMC]

I have the following problem when trying to access the Dropbox API:

Error: StatusCode=400, This app does not have permission for this operation.

At first I gave the API error, fix it by changing 0 to 1, but this does not give or backwards.

Some solutions working please?

What permissions does your app have? Dropbox or Sandbox?
Also when did you register? You probably need to use API 1.
Thirdly, what is the request you send out?

 

[JorgeMC]

I am using the following example:

http://www.b4x.com/forum/basic4andr...android-dropbox-oauth-tutorial.html#post59994

And change the API level 1, but I do not understand is if I use Dropbox or Sandbox, I use Dropbox.

 

[thedesolatesoul]

Did you register your app at: https://www.dropbox.com/developers/apps ?
So you have your own AppKey and AppSecret?
And you Access Type on that page is 'Full Dropbox'

Yes :sign0027:

 

[thedesolatesoul]

Also remember, until you App status is 'In Development' or something like that, you can only login with you own login credentials.
You have to use API 1.
And when do you get this error? Can you tell us the url that is sent out?

I`m using this example:

And this is the App from DropBox:

That is what is wrong? I do not understand ... :sign0163:

 

[thedesolatesoul]

I dont understand.
I have been using a modified form of this example for the past 8 months!
I am using API 0, but even when I change it to API 1 it works for me.

I think you need to double check your developerkey and secret, make sure that zeros and 'o's dont get mixed up?
Do you get this error at authentication screen?

 

[vb1992]

I think you were grandfathered in with your older dropbox developer account. Have you tried making a new one TDS? and testing that one?

 

[thedesolatesoul]

I'm sorry you are correct.
I keep looking at the REST API page and it doesnt seem to have changed.

The authentication flow has changed and there are two options:
1. Either login through a webview and pass the token back (this will be similar to the OAuth/Google Webservices Erel posted)
2. Or Login through the Dropbox official app

We could either wrap the official Dropbox SDK (not too intent), or we could just extract the Intents required to perform the authentication (this looks easier).

 

[vb1992]

"we could just extract the Intents required to perform the authentication"


And build a small library?

or straight with b4a code...

 

[thedesolatesoul]

Remember if we DO use intents, then we REQUIRE the official Dropbox app to be installed.

I dont think a library is necessary.
I cannot 'quote post' the intent due to certains reasons but here is the breakdown of the intents.

Sending the authentication intent:

Dim localintent as Intent
localintent.Initialize(localintent.ACTION_VIEW,"")
Dim str1,str2 as String
str1 = "db-" + localAppKeyPair.key;
str2 = str1 + "://" + 1 + "/test";
localIntent.setData(Uri.parse(str2)) '?? Dont know how to do this?
localintent.putExtra("EXTRA_INTERNAL_CONSUMER_KEY", consumerkey)
localintent.putExtra("EXTRA_INTERNAL_CONSUMER_SECRET", consumersecret)
localintent.Flags=268435456
startActivity(localIntent)

Receiving the result:
I think we need to use Activity.GetStartingIntent?

localIntent = Activity.GetStartingIntent
if (localIntent = null) then
      'No authentication
else
    Dim str1, str2, str3 as String
    str1 = localIntent.getExtra("ACCESS_TOKEN");
    str2 = localIntent.getExtra("ACCESS_SECRET");
    str3 = localIntent.getExtra("UID");
    tokenkey = str1
    tokenpair = str2
    return str3;
End if

Any ideas?

 

[vb1992]

TDS we can figure this out this weekend....
I am sure we can make it work one way or another!

Dropbox - Error: StatusCode=400

Did you ever create the wrapper?
I have the same problem. I set up my DropBox today and am using V 1
I get the same error.
In checking the DropBox Forum I find:

It look like you're trying to use the /token call with a new API key. The /token call has been deprecated in the latest version of out API and all new applications must use OAuth for authentication. You're using a 3rd party PHP SDK that doesn't seem to be updated to reflect these changes in our API. Please see our documentation for more details.

You might try looking at this (Dropbox-PHP) 3rd party SDK that says its been updated to use v1 of our API.

It looks to me that the token "function" has been deprecated. Is Erel's example needing update?
In any case, is there a fix for this?
Thanks,

[Tegwin]

I am having the exact same problem. i have changed the API to use 1 and when I login I get the same error .. I have copied and pasted the keys to ensure I have them right but still have the same problem.

Any ideas how I can get this to work

Thanks
