Zapier Code to auto invite users to slack

invite_to_slack.js

var slackTeam = "YOUR_SLACK_TEAM_NAME ";
var token = 'YOUR_ADMIN_TEST_TOKEN'; 
// A test token will suffice.
// You can generate one at https://api.slack.com/docs/oauth-test-tokens
// Just make sure that the user issuing the test token is an admin.

var url = 'https://'+ slackTeam + '.slack.com/api/users.admin.invite';
fetch(url, { 
  method: 'POST',
  headers: {'Content-Type': 'application/x-www-form-urlencoded'},
  body: "token="+ token + "&email=" + input.email
})
.then(function(res) {
  return res.text();
})
.then(function(body) {
  var output = {rawHTML: body};
  callback(null, output);
})
.catch(callback);

Wow! It worked! Thanks for sharing your work.

Perfect solution... much better than others I have been trying. Thank you!

Works! Thank you! Suggested tweaks to invite as a single channel guest to a specified channel?

This worked perfectly! Thank you so much!

@pluthena I need the same thing!

How to use this code in Zapier?

@EvgenSchastnyy Add the step named "Code", it is a built-in app by Zapier. Select JS, create the input data variable named email and map it to the email address from your trigger step.

Then paste the above JS code, but it seems the email variable should be named inputData.email to match how the current version of Zapier Code input data is named.

Many thanks for the solution!

Hey @dommmel any chance you have an updated script since Slack deprecated workspace tokens and now requires OAuth authentication flow?

Did anyone find out how to do this since the legacy tokens are now disabled?

Any update guys?
