Cannot get ouath/token to work - invalid_respose

[Troy]

I have tried to get the Authorization_code grant to work using the sample Node.js code provided.
I cannot get a valid access token back from the login.mypurecloud.com.au similar to another closed topic on the forum.

I have tried re-formatting the code to ensure the packet is as per the documentation as it appeared the sample code did not work.

I then tried Postman and using x-www-form-urlencoded and keep getting the same response.

The latest correlation Id is,
inin-correlation-id →7e3c899b-f027-4aca-7cb8-9d9af0a1b799 if that helps.

I have entered,
URL login.mypurecloud.com.au/oauth/token
grant-type = authorization_code
code = the Authcode we we got back from the Authvalidation.
redirect_uri = http://localhost:8086/oauth/callback

The Authorization is Basic Auth using the clientId:secret
Thanks for any help

can you share your code?

I noticed in your post you are using grant-type, not grant_type. That form param is supposed to use an underscore. If that's not the issue, as Kevin asked, please share your code for your login process.

Thanks for looking at this. At this stage I can't get this to work on Postman.
This was a typo in the, I am using grant_type in the request.

This is a version of code, modified from the provided example. I have tried a few approaches to try and get the request correctly formatted the form data and authorization. This was the latest version where I tried to force the headers and coding.

app.get("/oauth2/callback", function(req,res){
var authCode = req.query.code;
var tokenFormData = grant_type=authorization_code&code=${authCode}&redirect_uri=http://localhost:8086/oauth2/callback;

var postData = {
    url:'https://login.mypurecloud.com.au/oauth/token',
    headers: {
        "content-type" : "application/x-www-form-urlencoded",
        "Authorization":"Basic "+new Buffer.from(client_id+":"+client_secret).toString("base64")
    },
    body: tokenFormData
}

//post back to /oauth/token with the client id and secret as well as the auth code that was sent to us.
request.post(postData, function(err,httpResponse,body){
    console.log(body);

    var tokenResponse = JSON.parse(body);
    var sessionId = uuid.v4();

    sessionMap[sessionId] = tokenResponse.access_token;
    res.cookie('session', sessionId);
});

});

For the postman config, be sure you're using https in your URL; auth and the API only work over HTTPS. What is the error body you're getting? It should contain a message indicating what was wrong with the request.

For your code, what's the error body you're getting there?
