... all needed, including refresh token. 😉

In the SDK for javascript that`s the "get access token from code"?, how could I use it to get the refresh token?

You cannot! Access token is generated from refresh token, not opposite!!! Didn't you read all posted till now? 🤷

Alex_Ch When using the OAuth app authorization flow, Dropbox gives an "authorization code" (sometimes also called "access code") that can be exchanged (once) for the access token and optional refresh token. As Здравко said, that resulting refresh token can then be used to retrieve further access tokens as needed. There's an example of that flow in this blog post. That's the same flow implemented by the JavaScript SDK, such as in this example.

Excuse me if I confuse with something, this topic is kinda new to me

I`ve been testing the auth flow, and when I tried to get the authorization code I got a login screen. Is there another way to get the authorization code without that login? The app only needs access to my own account

No, it's not.

Ok, so you need to perform OAuth (including receiving access code) once, as Greg said, and no more. Once you have refresh token you don't need to open any login screen. The refresh token, application key, and (optionally - becomes mandatory for no PKCE) application secret are enough for automatic access token regeneration without any further user interaction (including interaction to you).

Ok, I think I finally got it.

Just one more thing. In the SDK for javascript, I tried to use the command "refreshAccessToken", but it doesn´t read the scopes, I always get the "Scope must be an array of strings" error, even when I define the array in the property.

Where could I find an example of that command? I think I´m using the syntax wrong 

Alex_Ch You do not need call refreshAccessToken yourself, unless you need to retrieve a client with a sub-set of the authorized scopes. The SDK will automatically perform the refresh process for you automatically for the currently authorized scopes without you calling refreshAccessToken in your own code.

If you do want to call refreshAccessToken explicitly though, you could do so like this:

dbx.auth.refreshAccessToken()
  .then(function() {
    // ...
  })
  .catch(function(error) {
    console.error(error);
  });

To call refreshAccessToken with a specific set of scopes, pass in a list like this:

dbx.auth.refreshAccessToken(["account_info.read", "sharing.read"])
  .then(function() {
    // ...
  })
  .catch(function(error) {
    console.error(error);
  });
