  • In your WordPress site, click the “Plugins” link.
  • Click the “Upload Plugin” button.
  • Click “Choose File” and select add-on files.
  • Click “Install Now” and then “Activate Plugin”.

Now we need to fill in three different options:

  1. Service URL.

This URL is used to hook to the Slack API to send messages. The URL follows this pattern:<hash-path>

You can generate a new URL following the steps:

  1. Log in on

  4. Click on “Add Incoming WebHooks Integration”.
  5. Copy the new WebHook URL.
  6. Go back to the Slack add-on tab and paste the URL:

Step #2. Enter Username

You can choose anything you want for this option. This is the username displayed in the notification.
