I am using VB Code, Here is code:

request = DirectCast(WebRequest.Create(" HTTP/1.1"), HttpWebRequest)

Dim Credidentials As String = "NF3Unhp_R4yBV2QoMNM0yw" & ":" & "3ONXJwFDS2akvz2CaPZX9AaGAzR8uPTUS1h4z80lGtcA"

Credidentials = Convert.ToBase64String(Encoding.Default.GetBytes(Credidentials))

' Add authentication to request

Dim Userdata As String = "grant_type=password&username=12143477228&extension=101&password=POR2008$"

request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8"

request.Method = "POST"

request.Host = ""

request.Headers("Authorization") = "Basic " & Credidentials & "&" & Userdata

request.Accept = "application/json"

ServicePointManager.ServerCertificateValidationCallback = AddressOf AcceptAllCertifications

return error : the remote server returned an error: (404) Not Found

I just want to get access token, then I can continue to do next api call.

Yes, need to take care the url part as documents are sometimes misleading.. like the case here where you were appending HTTP/1.1 in url which is wrong.

Things need to be noticed by developers while copying examples from documents

Could you provide the final HTTP POST request you used (minus your API keys) so we can compare and update our documentation (in case this fouls up any other developers)?

I got it work, I remove HTTP 1.1 in URL, In RingCentral Document, there is http 1.1 required, that's wrong. anyway, Thanks for help.

I did test in API console, and got Access_token, I used same Credidentials in HttpWebRequest, just did not work. (401) Unauthorized. it's weird.

thanks. I move UserData to body, get different error:  (401) Unauthorized.

I am using sandbox environment. and sand box account

This has been made private because app and user credentials have been included in the post. Please do not post your app secret or user passwords openly.

I'm not sure why you are receiving a 404 (is it confirmed to be sending to https?).

User data is supposed to be in the body, not in the Authorization header.
