Error in generating token file through DropBox Token Authorization Tool

What's the URL for the page you get a 404 on? Can you share the relevant code?

I got the same error today. This is the DropBox Token Authorization Tool, no code on my part is involved.

Can you share the specific steps to reproduce this problem so we can look into it? Thanks in advance!

1. I created my appkey and app secret today
2. I ran DropBoxTokenIssuer.exe (delivered with SharpBox installation) and filled out the key and secret, and specified c:\TestToken.txt as my output file. It says "PingTest would like access to its own folder, Apps › PingTest, inside your Dropbox". There are "Cancel" and "Allow" button below this message.
3. I clicked on "Allow" - got this error: The website cannot display the page HTTP 500
   Most likely causes: The website is under maintenance. The website has a programming error.

I do have a folder named "PingTest" in my dropbox account; I also have dropbox desktop client installed on my machine.

Thanks! That's helpful. I was able to reproduce this issue, and it looks like the 500 error is actually being returned by sharpox.codeplex.com (which is presumably a typo in the code which should be sharpbox.codeplex.com), after dropbox.com redirects there. That being the case, this is something the developer of DropBoxTokenIssuer.exe/sharpox.codeplex.com will need to fix:

Sorry I can't be of more help!

I am wondering: dropbox.com website itself does not provide this tool? It generated my appkey and secert for me, it seems a resonable request that it should also provide this tool to generate token file.

The token this tool generates is called an "access token", which is user-specific. Normally, a Dropbox API app is used for a large number of users (not just the developer/owner of the app). That being the case, the normal way to get a token is to send each user through an OAuth flow (as the tool does) and store the token. (The user normally doesn't need to see or handle the token themselves.)

If you do want to be able to quickly get an access token for an app on your own account though, the App Console does have a button for generating one. Note that it generates an OAuth 2 access token though, whereas the DropBoxTokenIssuer.exe tool retrieves an OAuth 1 access token.
