Hi. I send the following form data with the code I got from the authorization page. I use redirect_uri back to my app through localhost. However I get the following response (error code 400): "No...

Dropbox Community ModeratorThanks! That may have just been a transient issue on our side. Can you try once more now? Please share the X-Dropbox-Request-Id again if you still get a 500.
- Still get 500. X-Dropbox-Request-Id: 04f52af12d3fa4ab1f040ec979addd8b
- Greg-DBThanks for letting me know. We'll look into it.
Any chance you'd had the time to look into this? I got everything else working for next release of my app ;)
- Greg-DBThis is open with the team, but I don't have an update on it yet. I'll follow up here once I do.
Any news? I really need this to release next version of my app and dropbox backup is the number one requested feature from my costumers ;)
- Greg-DBThis is open with the team, but I don't have an update yet.
Can you check if you're still seeing this though? I don't know what the underlying cause was yet, but it may have just been a transient issue. I still get the same error. If you guys have Unity installed, I can send you a sample project that produces the error?
- Greg-DBSure, that may help us investigate. Thanks!
Hi. I have the sample code ready. Where can I mail it securely? For your convenience, it contains my app secret keys etc.

- Greg-DBThanks! You don't need to include the app secret, but in any case you can submit it in an API ticket here:
https://www.dropbox.com/developers/contact Thanks. Ive submitted instructions as wel as link to download (in my dropbox)
Just mail me if questions :)

- Hi sir,
I have encountered the same problem.
It bothered me a while.
Is this the problem solved?
Could you tell me how to do?
Thanks in advance!! Actually my problem was that I accidentially upper cased the request code, due to copy paste og some other code ;)
So I guess you need to make sure that the code you get from Dropbox API is not modified in any way, before you request the token

In my case I had this issue because I was using the wrong content type to post the data.
This endpoint is actually very confusing because unlike all the other endpoints (which accept application/json) it accepts application/x-www-form-urlencoded, and if you use the wrong format it will respond with this absurd error message "No auth function" even though there can't be an auth token at that point.In my tests other mistakes in the data format (like missing client ID or secret) also resulted in this error .
From the doc it's unclear whether client ID and secret are required or not (I have no idea what "If credentials are passed in
POSTparameters" means in this context) but they seem to be required anyway.So in my case I eventually got it working using this kind of request:
curl -v -F 'client_id=REMOVED' -F 'client_secret=REMOVED' -F 'code=REMOVED' -F 'grant_type=authorization_code' https://api.dropboxapi.com/oauth2/token
