401 unauthorized error

What language is this? What library? Are you using OAuth 1 (with HMAC signing or PLAINTEXT?) or OAuth 2?

Could you share some code?

Hi Steve,

Thanks for your reply.

I am consuming Dropbox REST API methods using C#.Net Web Request.

We are using OAuth 1 with HMACSHA1 signing.

If you required code I will share you the sample.

Thanks & Regards

Please do share your code. But I would strongly suggest switching to either PLAINTEXT signing or OAuth 2. HMAC signing is difficult to get right, and the issue likely relates to URL encoding.

Hello,

I'm getting the 401 error when trying to download a copy of my document to my computer from the online word. Any clue how to fix this??

Hi Dana, this thread is about an issue with the Dropbox API for developers. If you're not a developer programming an app, the Bugs & Troubleshooting forum would be a better place for help with your error.

Hi Sherry, it sounds like you’re experiencing an issue with a third party application. Please reach out to the support organization for that app for help. If the developers of this app are having any trouble with the Dropbox API itself, they can reach out to Dropbox developer support directly with the relevant technical details.
