How I can connect my extension to the API? I tried to use this example code for connecting:

    clientId: 1,
    key: '?',
    channelUrl: '?',
    complete: function (data) { alert('connected') }
    success: function(data) { alert('ok') },
    error: function(data) { alert('error') },
    networkUsers: true

Which value I should put in channelUrl? And how I can register app and get token key, if it will work locally?

    If anyone still has this issue, comment @ reply to me here and I will write up an answer. (But current low view count suggests very little interest.) And anonymous feedback is not promising either. Commented Aug 23, 2018 at 21:45

I've built an extension that uses StackExchange API using OAuth2 flow. I did not use the JS SDK and did it manually instead.

Here is how I did it:

function auth(sendResponse) {
  const scope = 'read_inbox,no_expiry,private_info';
  const clientId = '12364';
  const redirectUrl = chrome.identity.getRedirectURL('oauth2');
  const url = `https://stackoverflow.com/oauth/dialog?client_id=${clientId}&scope=${scope}&redirect_uri=${redirectUrl}`;
    { url: url, interactive: true },
    redirect_url => {
      const token = redirect_url.match(/access_token=(.+)/)[1];
      sendResponse({ token });

    This code works perfectly. But make sure to add the redirectUrl for your app as chromiumapp.org in the OAuth Domain in your stackApp configuration - reference (stackoverflow.com/a/31169304/6908282)

  • can you confirm if the OAuth Domain needs to be stackexchange.com instead. Because firefox has a different domain allizom.org, due to which i'm not able to use the plugin in firefox.
