Hi emretezisci,

Haha..😁 Ok, Yes, a little confusing message, maybe. Don't catch to the words. What grant type you are declaring in fact? 🧐 Nothing? 🤔 🙃 It's something required, cannot be nothing. 😉

Hope this gives direction.

    Oh I think it was deducted for some reason. 

    {
  "body": {
    "grant_type": "refresh_token",
    "refresh_token": "<token>"
  },
  "contentType": "application/json",
  "followRedirect": false,
  "headers": [
    {
      "key": "Authorization",
      "value": "Basic <key>"
    }
  ],
  "method": "POST",
  "timeoutSeconds": 5,
  "url": "https://api.dropbox.com/oauth2/token"
}

    I use refresh_token.

      In addition why are you using application/json encoding? It requires application/x-www-form-urlencoded POST parameters. 😉

        Thanks, for your prompt responses. I am making these requests from another integration that doesn't support application/x-www-form-urlencoded.

        Do you know any other way to make it work with an application/json encoding?
