I am trying to add a logout call into a front end app that i'm building, that uses SF for the auth features. When logging in, i successfully get the instance url, profile string and access token as expected.

However, when i try to call the logout string, it always throws an error and never kills the session in SF. Here is my express code:

      (req, res) => {
        console.log(`about to call this url: ${req.user.sfInstanceUrl}/services/oauth2/revoke?token=${req.user.sfAccessToken}`)
        // call the url to logout from Salesforce
          'Authorization': 'Bearer ' + req.user.sfAccessToken
        .then(result => {
          console.log(`was there any result from the axios call? ${JSON.stringify(result)}`);
        }).catch( err => {
          console.log(`we caught an error: ${JSON.stringify(err)}`);

Now, when this gets executed, i always end up in the error block with a status 400 error and little other information... The get URL that is logged out at the top looks correct. When i try this flow in postman, it works and the session gets killed and i get a status 200 back from salesforce...

Is there something i've missed in that GET request? The documentation still says that GET requests are supported for logout - but this one doesn't work..

    For one, you don't need the Authorization header. The error message is probably in the body of the response. If you can reproduce the issue with a command-line client such as curl and post the request/response, it would help. Postman does not count as a command-line client. Depending on its config, Postman auto-adds headers and messes with input/output. – identigral Sep 19 at 18:38

    the actual issue was in my postman handler. upon subsequent logins i wasn't updating the originally stored access token with the new one returned from the auth flow... code is hard :| thanks for the nudge in the right direction identigral :) This really helped.. – adam.sellers Sep 21 at 21:23
