Invalid user credentials

I’m trying to send post request(as said in docs) to get access token but instead of token I’m getting this:

{"error":"invalid_client","error_description":"The client credentials are invalid"}

client_secret & client_id are right. I even tried to create a new keys but it didn’t make it work.



part of my code.

Code:
var params = "client_id=" + id + "&client_secret" + secret +"&grant_type=authorization_code&redirect_uri=https%3A%2F%2Fsnackimpact.mautic.net%2F&code=UNIQUE_CODE_STRING"; console.log('in...'); xhr.open("POST", combo1); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xhr.onreadystatechange = function() { console.log(xhr.responseText); if(xhr.readyState == 4 && xhr.status === 200) { var res = xhr.response; var parse = JSON.parse(res); } console.log(status); }; xhr.send(params);
I don't think that it is error on my side i.e. all credentials are right.
Cheers,
Ivan.
