POST 401 Authorization Error on Revoke Endpoint

[clwalls]

Hey All and Gordon,

I am trying to revoke an access token following the recent header requirements post and the documentation. 

My TS function is

    var params = "token=" + this.fitbitToken; //grabs properly from firebase

    var xhr = new XMLHttpRequest();

    xhr.open('POST', 'https://api.fitbit.com/oauth2/revoke');

    xhr.setRequestHeader("Authorization", 'Basic [BASE64 Encoded (client_id):(client_secret)')];

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

    xhr.onload = function () {

        if (xhr.status === 200) {

            console.log("SUCCESS")

            console.log(xhr.responseText)

        }

    };

    xhr.send(params);

  }

I have not included the content length new header requirements as that will not be implemented till May, but am still receiving a 401 error.

Any advice on how to fix this error? Thanks!

Resolved!

Had to look into the HTML response (which I thought I had done previously) to see that I was sending a bad token.

I diagnosed this by getting the client access_token once again and manually pasting it into my code.
