Setting up OAuth

You'll need to set up OAuth if you're building an integration with Intercom that accesses other peoples' Intercom data. This can be done in a few simple steps:

Setting up OAuth

After you complete these steps, you'll be able to use your access token to execute the actions authorized by an Intercom customer.

Accessing your own data only

If you just want to access your own Intercom data, you can use Access Tokens.

If you're unsure what you need, click here to get more context on the two options.

Provide the initial information

Each development workspace automatically gives you the option to use OAuth. To start, tick the Use OAuth option on your Authentication page in the Developer Hub.

OAuth_blurred

You'll now have two sections to fill out:

Redirect URLs

This is the URL which we POST to when your user has authorized your app to access their information. In other words, it's the URL that Intercom will use to send the authorization code for your user.

❗️ Redirect URLs must use HTTPS
The redirect will need to communicate over a TLS/SSL connection, so the URL will need to be over HTTPS.

Callback blurred

Multiple Redirect URLs

You can provide multiple URLs by selecting the Add redirect URL option after specifying your initial one. The first will always be the default.

After approval, you can choose which URL to use when you're initiating the OAuth flow via the redirect_uri parameter. This means you can include testing as well as production URLs here.

Permissions

Permissions let you specify exactly how your application needs to access an Intercom user's account.

You should only specify the scopes you definitely need for your use case. It's best practice as these will go up for review when you submit your app for review.

🚧 Scopes automatically being selected
If your app utilizes Canvas Kit, certain permissions are required by default due to the data your app will have access to. The following scopes will be automatically selected and cannot be deselected:
Read and list users and companies
Read conversations
Read admins
Gather App data

The following permissions can be selected via checkboxes on your Authorization page:

People & conversation data

Standard scopes	Description
Read and list users and companies	List and view all segments, users and companies
Read and write users	List all users and execute bulk actions
Write users and companies	Create and update users and companies

Selecting webhook topics

Webhook topics are related to corresponding permission scopes. For example, if you need to setup a webhook to trigger when a user/lead is created then you will need to select the "Read and write users" permission scopes. You will then be able to setup the webhook topics for your app which will fire for each workspace it is installed on. Checkout our docs on setting up webhooks for more detailed information on how to enable webhooks for your app.

Get the authorization code

You'll first need your client_id and client_secret. These can be found on the Basic Information page for your app in the Developer Hub.

Basic information

To get the Authorization Code, you will need to redirect your user to the following URL:

https://app.intercom.com/oauth?client_id=___&state=___

client_id: Your app's Client ID (see above)
state: A random session specific string which we will return in the callback to allow you to identify the session and mitigate CSRF attacks

Your user will be presented with the permissions that your app is requesting. Once the user approves this request, they are redirected back via the Redirect URLs which you provided earlier.

The request to your Redirect URL will have 2 URL parameters: code and state. For example:

https://yourapp.com/callback?code=___&state=___

code: This is the Authorization Code you will use to retrieve an Access Token
state: This should be the same as the state string you passed to the Authorization Code endpoint above

Trade your authorization code for an Access Token

We can now exchange the code for the Access Token with a POST request to:

https://api.intercom.io/auth/eagle/token

with the following parameters in the body:

code: The Authorization Code received above
client_id: Your app's Client ID from the Developer Hub (see above)
client_secret: Your app's Client secret from the Developer Hub (see above)

A successful request will receive a response with the following parameters in the body of the response:

token_type: Always 'Bearer'
token: The Access Token
access_token: A duplicate of the Access Token above

{
  "token_type": "Bearer",
  "token": "dG9rOjBiM...",
  "access_token": "dG9rOjBiM..."
}

Use your token

Now that we have the authorized token, we can use this to execute some action on behalf of our user.

For example, to retrieve the admin and app information associated with the Access Token:

curl --request GET \
     --url 'https://api.intercom.io/me' \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <ACCESS_TOKEN>'

// npm install api --save

const sdk = require('api')('@intercom-api-reference/v2.8#132bo2vleh7syud');

sdk.auth('<ACCESS_TOKEN>');
sdk.identifyAdmin({'intercom-version': '2.8'})
  .then(({ data }) => console.log(data))
  .catch(err => console.error(err));

import requests

url = "https://api.intercom.io/me"

headers = {
    "accept": "application/json",
    "authorization": "Bearer <ACCESS_TOKEN>"
}

response = requests.get(url, headers=headers)

print(response.text)

require 'uri'
require 'net/http'
require 'openssl'

url = URI("https://api.intercom.io/me")

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true

request = Net::HTTP::Get.new(url)
request["accept"] = 'application/json'
request["Intercom-Version"] = '2.8'
request["authorization"] = 'Bearer <ACCESS_TOKEN>'

response = http.request(request)
puts response.read_body

// composer require guzzlehttp/guzzle
<?php
require_once('vendor/autoload.php');

$client = new \GuzzleHttp\Client();

$response = $client->request('GET', 'https://api.intercom.io/me', [
  'headers' => [
    'Intercom-Version' => '2.8',
    'accept' => 'application/json',
    'authorization' => 'Bearer <ACCESS_TOKEN>',
  ],
]);

echo $response->getBody();

An example, successful response would be:

{
  "type": "admin",
  "id": "2633609",
  "email": "hermione.granger@awesomecorp.io",
  "name": "Hermione Granger",
  "email_verified": true,
  "app": {
    "type": "app",
    "id_code": "drzzt019",
    "name": "Hogwarts workspace",
    "created_at": 1661876617,
    "secure": true,
    "identity_verification": true,
    "timezone": "Europe/Edinburgh",
    "region": "US"
  },
  "avatar": {
    "type": "avatar",
    "image_url": "https://static.intercomassets.com/avatars/56395503/square_128/5449623-166556.jpg"
  },
  "has_inbox_seat": true
}

Use OmniAuth instead

We have added support for Intercom to number of OAuth libraries. It makes the setup process much easier, so it is a good way to setup OAuth for your app:

For Rails apps, use Intercom strategy for OmniAuth.
For Node.js apps, use Intercom Strategy for Passport.
For PHP apps, use Intercom Provider for PHP League's OAuth 2.0.
For GO apps, use GOTH library. To prevent user impersonation, check that user.RawData["email_verified"] is set to true in the response.

Example Ruby Code

Intercom provides some Ruby sample code that you can use to allow the user to authorize MyApp's request via a "Connect with Intercom" button.

Firstly, you will need to generate a Self Signed Certificate and a Private Key if you don't have SSL setup on your site. You can do so like so:

openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout pkey.pem -out cert.crt

Now you can use this very simple Sinatra setup with one of your publicly available endpoints to test the OAuth flow:

<a href="https://app.intercom.com/oauth?client_id=<XXXXXXXXXXXX>&state=example"><img src="https://static.intercomassets.com/assets/oauth/primary-7edb2ebce84c088063f4b86049747c3a.png" srcset="https://static.intercomassets.com/assets/oauth/primary-7edb2ebce84c088063f4b86049747c3a.png 1x, https://static.intercomassets.com/assets/oauth/primary@2x-0d69ca2141dfdfa0535634610be80994.png 2x, https://static.intercomassets.com/assets/oauth/primary@3x-788ed3c44d63a6aec3927285e920f542.png 3x"/></a>

# This code snippet shows how to enable SSL in Sinatra+Thin.
#

require 'sinatra'
require 'thin'
require 'json'
require 'slim'

class MyThinBackend < ::Thin::Backends::TcpServer
  def initialize(host, port, options)
    super(host, port)
    @ssl = true
    @ssl_options = options
  end
end

configure do
  set :environment, :production
  set :bind, '0.0.0.0'
  # set :port, 443
  set :server, "thin"
  class << settings
    def server_settings
      {
          :backend          => MyThinBackend,
          :private_key_file => File.dirname(__FILE__) + "/pkey.pem",
          :cert_chain_file  => File.dirname(__FILE__) + "/cert.crt",
          :verify_peer      => false
      }
    end
  end
end

get '/' do
  File.read('intercom.html')
end

get '/home' do
  "Welcome Back"
end

get '/callback' do
  code = params[:code]
  state = params[:state]
  puts "CODE: #{code}"
  puts "STATE:#{state}"
  redirect '/home'
end

The full code example can be found here. You can copy the Intercom JS to a file, and reference it in a page where a user can click through to provide authorization. Then you will need to have a route for the Redirect URL you provided.

When you run your server and click through to authorize the user, you should see something similar outputted on the terminal:

> ruby ssl_server.rb

Thin web server (v1.6.4 codename Gob Bluth)

[05/May/2016:10:15:49 +0000] "GET /home HTTP/1.1" 200 12 0.0005

Trade your authorization code for an access token

We can now exchange the code for the Access Token with a POST request to the Intercom Eagle endpoint.

For the simplified purposes of understanding the flow, add the following code to you callback route:

# We can do a Post now to get the access token
  uri = URI.parse("https://api.intercom.io/auth/eagle/token")
  response = Net::HTTP.post_form(uri, {"code" => params[:code],
                                       "client_id" => "XXXXXXXXXXXX",
                                       "client_secret" => "YYYYYYYYYYYYY"})

  # Break Up the response and print out the Access Token
  rsp = JSON.parse(response.body)
  puts "ACCESS TOKEN: #{rsp["token"]}"

    end
  end
end

  File.read('intercom.html')
end

  "Welcome Back"
end

  #Get the Code passed back to our redirect callback
  @code = params[:code]
  @state = params[:state]
  puts "CODE: #{@code}"
  puts "STATE:#{@state}"

  #We can do a Post now to get the access token

  puts "ACCESS TOKEN: #{rsp["token"]}"
  redirect '/home'
end

post '/callback' do
 push = JSON.parse(request.body.read)
 puts "I got some JSON: #{push.inspect}"
end

When you run your server and click through to authorize the user, you should now also see the "Access Token" output on the terminal:
