Trouble getting Access token

Hi. I'm new to APIs. I know there are articles on how to obtain an Access token, but I'm still stuck. I'm using Rest Fox and trying to POST to https://secure.myob.com/oauth2/v1/authorize/ with the appropriate information, but I get a 502-Bad Gateway error. Being new, I'm not sure if it's the URL, or the credentials, or something else that is wrong. Could someone help please?

    Hi Mo_JM , you need to encode both the redirect URL and the authorization code itself.

     

    EG:
    code=Wvof%21IAA[[TRUNCATED_FOR_READABILITY]]luF&redirect_uri=http%3A%2F%2Flocalhost%2Fmyob_redirect%2F&client_id=[[MY_API_KEY]]&scope=CompanyFile&client_secret=[[MY_SECRET]]&grant_type=authorization_code

    Hi,

     

    I am trying to get access token but getting 400 bad request

    {

    "error": "invalid_grant",

    "error_description": "The provided authorization grant (e.g., authorization code, resource owner credentials) or refresh token is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client. The authorization code has already been used."

    }

    Need your help

    Any word on this at all. All my integrations have stopped. On the redirect, I'm getting 

    Can’t reach this page
    Make sure the web address http://desktop is correct

    I'm getting the same error. 

    This was working fine until Monday and it stopped since yesterday.

    Hi Mo_JM,

     

    I get that you're having a 502-Bad Gateway error. Hopefully another developer in the community can get you a response soon, otherwise feel free to reach out to the support team via developer.myob.com.

     

    Best regards,

    Doreen

      Hi Doreen. I can offer a little more now on my problem, but of course I still don't know why it's happening (I'm new). I'm POSTing via Rest Fox to   https://secure.myob.com/oauth2/v1/authorize

      Header: application/x-www-form-urlencoded

      Body: client_id my id

                client_secret  my secret

                Scope  CompanyFile

                redirect_uri  http://desktop (as per my login)

                Code   the code I got in the authorization step

               Grant_type   authorization_code

       

      When I POST this I get a 502 error. BUT, once when I accidentally had authorisation_code (the Australian spelling) I got a 400 code error. I only get a 400 code if I mistype in this spot. No other mistypes cause this.

      Does this shed any further light on my problem?
