DropBox API Invalid or missing signature

I'm trying to enable dropbox manipulation via API provided in DropBox series

Here is the url generated:

https://api.dropbox.com/1/metadata/sandbox/public/2WayServiceOverview.pdf?oauth_consumer_key=XXXXXX&oauth_nonce=5382801&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1354311566&oauth_token=XXXXXXXXXXXX&oauth_version=1.0&oauth_signature=5ooZ4PP5V85bi28aI6pKQfahWpY%3d

Of course some data I replaced to not share all :-)

Authorization passes, I get access code and then getting {"error": "Invalid or missing signature"}

File public/2WayServiceOverview.pdf exists for sure. What I am doing wrong? Is it maybe about oauth_signature_method?

Since you're using HTTPS, you can use the much simpler PLAINTEXT signature method. For you, this means:

  1. Set oauth_signature_method=PLAINTEXT
  2. Set oauth_signature=urlencode(app_secret + "&" access_token_secret)

It might be easier to pass OAuth credentials via an HTTP header instead of via URL query parameters. See point 4 of this article: https://www.dropbox.com/developers/blog/20
