OAuth2 authentication - "unsupported_grant_type" error at /access_token/ method

[Fandroide]

Hi,

I'm not sure if anyone using Freesound API has experienced this issue when trying to get an access token using a web client:

- Method: https://freesound.org/docs/api/authentication.html#step-3

- Error: {"error": "unsupported_grant_type"}

- Code:

var xhr = new XMLHttpRequest();

xhr.open("POST", 'https://freesound.org/apiv2/oauth2/access_token/', true);

xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

xhr.send(JSON.stringify({

   client_id: 'CLIENT_ID',

   client_secret: 'CLIENT_SECRET',

   code: 'AUTH_CODE ',

   grant_type: 'authorization_code'

}));

I tried with 'Content-Type': 'application/json' but still same result.

PS. In POSTMAN seems to be working fine for example.

Thanks in advance!

Hi again,

I found the way to make it work by this request:

fetch("https://freesound.org/apiv2/oauth2/access_token/?client_id="+CLIENT_ID+"&client_secret="+CLIENT_SECRET+"&grant_type=authorization_code&code="+AUTH_CODE+"", {

method: "POST"

}).then(response => response.json()).then(response => console.log(JSON.stringify(response)))

I hope it helps someone else.
