Attempting to login using Oauth Implicit Grant, using docs: https://developers.digitalocean.com/documentation/oauth/

Sample auth request:

https://cloud.digitalocean.com/v1/oauth/authorize?scope=read&client_id=123&state=k3uWpyJb&redirect_uri=https://789.ngrok.io/auth&response_type=token

After entering credentials, the URL received at the callback contains no parameters.

Expected behaviour: should have a token parameter.

token data is returned in fragment/hash part of the url. You have to parse the url’s hash in order to read the token.
Sample code using with Javascript:

let result = window.location.hash.substr(1).split('&').reduce(function (result, item) {
            var parts = item.split('=');
            result[parts[0]] = parts[1];
            return result;
        }, {});
console.log(result);
