Powershell Oauth2 Refresh Token
Hey all! Thanks in advanced. I am trying to write a powershell script to get an offline refresh token so I can do unattended uploads. The problem is that I have to authenticate for an author...
I'm not sure what you mean when you say you are "not getting any type of response from the curl command". For reference, if you need to debug something with curl, you can use the "-v" flag to enable verbose mode.
In any case, I haven't tested your new code, but the parameters look right. I also don't see where you retrieve the access token from the new /oauth2/token call, but assuming you do either manually or in code not shown, it seems right. Does it work for you when you run it?

Dropbox StaffI see you are requesting the refresh token, but you don't seem to actually be using it anywhere in the code you shared.
Whenever you need a new short-lived access token, you should call /oauth2/token with grant_type=refresh_token, as shown in step 5 of the offline example in this post.
So I used this code to upload files. I tried using the refresh token and it doesn't work...
$refresh_token = "hssEaww....REFRESHTOKENWENTHERE"
$headers = @{
Authorization = "Bearer $refresh_token"
"Content-Type" = "application/octet-stream"
}
# Read the file as a byte array and upload it to Dropbox
$file_bytes = [System.IO.File]::ReadAllBytes($file_path)
$outputFile = Split-Path "C:\FILEHERE.TXT" -leaf
$TargetFilePath = "/$outputFile"
$arg = '{ "path": "' + $TargetFilePath + '", "mode": "add", "autorename": true, "mute": false }'
$authorization = "Bearer " + $refresh_token
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", $authorization)
$headers.Add("Dropbox-API-Arg", $arg)
$headers.Add("Content-Type", 'application/octet-stream')
$response = Invoke-RestMethod -Uri https://content.dropboxapi.com/2/files/upload -Method Post -InFile $SourceFilePath -Headers $headers

Access tokens and refresh tokens are different objects and are not interchangeable, so you can't use a refresh token as an access token like that. Instead, whenever you need a new short-lived access token you should call /oauth2/token with grant_type=refresh_token and refresh_token set to the refresh token, like in step 5 of this example. That call will return a new short-lived access token which you can then use to make further API calls, such as /2/files/upload.
Is this correct? If so, I'm not getting any type of response from the curl command
$refreshToken = "REFRESHTOKENHERE"$appKey = "APPKEYHERE"$appSecret = "APPSECRETHERE"refresh_token = $refreshTokengrant_type = "refresh_token"client_id = $appKeyclient_secret = $appSecret}$response# Set up the URL to upload the file# Set up the request headers with the authorization and content-type$headers = @{Authorization = "Bearer $access_token""Content-Type" = "application/octet-stream"}- Greg-DB
