"error_description": "missing required field \"grant_type\""
I am trying to get a sl access token with my refresh token but it gives this error. Any idea why? Input: {

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?
To be honest, I haven't tried (haven't need), but you may do it by "hands". Shouldn't be so difficult to join names and value using = and & (no additional encoding steps needed in particular - all value are URL compatible already). Right? 🙂

emretezisci The /oauth2/token endpoint does not support those parameters being passed as "application/json"; they'll need to be passed as "application/x-www-form-urlencoded".
While it is recommended to use some library or platform functionality to have that built automatically, as Здравко said you can otherwise try to build that directly.
Is there any other server-side authentication option that doesn't require "application/x-www-form-urlencoded"?
