Intercom Messenger Not Showing on Website

How to fix it

Try these in order — the most common fix is first.

1. 1. Check the ping request

   Copy steps
   1. Open the browser console (Ctrl+Shift+J / Cmd+Option+J) and go to Network
   2. Reload and filter for 'ping'
   3. If ping is present the snippet loads; check its Response tab for 403 or errors
   4. If absent, run Intercom('show') in the console and reinstall the snippet
   Did this fix it? Yes No

2. 2. Check Messenger settings

   Copy steps
   1. Go to Settings > Channels > Messenger > Install and turn on user traffic
   2. Check Settings > Channels > Messenger > General for audience rules and 'Keep your Messenger secure'; add your domain as trusted
   3. Make sure the Messenger is not hidden before launch
   Did this fix it? Yes No

3. 3. Fix the snippet

   Copy steps
   1. Use the visitor snippet for logged-out visitors and the user snippet for logged-in users
   2. Replace the app_id placeholder with your workspace ID
   3. Place it just before the closing </body> tag; in single page apps follow the SPA guide and load the snippet before calling Intercom('boot')
   4. Remove custom CSS or edits to the install code and check hide_default_launcher
   Did this fix it? Yes No

4. 4. Rule out blockers and conflicts

   Copy steps
   1. Disable ad blockers or allowlist js.intercomcdn.com and retest outside private browsing
   2. On WordPress, log out of the admin and use WordPress 4.2.0+ and PHP 5.6+
   3. For 409 errors, archive duplicate users or send a unique user_id
   4. On shared domains like herokuapp.com, use a custom domain
   Did this fix it? Yes No
