Install the WPSSO JSON Add-on

JS Morisset

If you purchased the WPSSO Schema JSON-LD Markup Pro add-on, you received an email with a unique Authentication ID that will be required to install and update the Pro version. The WPSSO JSON Pro add-on uses many WPSSO Core Pro features and requires an active and licensed WPSSO Core Pro plugin. Make sure you have purchased and installed the WPSSO Core Pro plugin before installing the WPSSO JSON Pro add-on. ;-)

WPSSO Core Plugin Prerequisite

WPSSO Schema JSON-LD Markup (aka WPSSO JSON) is an add-on for the WPSSO Core plugin — to install and activate the WPSSO JSON add-on, you must already have installed and activated the WPSSO Core plugin. ;-)

Install the Add-on

  1. Go to the admin section of your WordPress site.
  2. Select the SSO menu item.
    • Free version:
      • Select the Complementary Add-ons settings page.
      • Scroll down and locate the “WPSSO Schema JSON-LD Markup” add-on.
    • Pro version:
      • Select the Pro Licenses settings page.
      • Scroll down and locate the “WPSSO Schema JSON-LD Markup” add-on.
      • After purchasing the WPSSO JSON Pro add-on, you will have received an Authentication ID for WPSSO JSON Pro by email. Enter that Authentication ID in the “WPSSO JSON Authentication ID” input field and save the settings.

        All Pro add-ons require an active and licensed WPSSO Core Pro plugin — if the Authentication ID input field is disabled, this indicates that the WPSSO Core Pro plugin needs to be purchased and installed first. ;-)

  3. Click the Plugin Details and Install link.

    If the link is named Plugin Details instead (no “Install” in the name) then the add-on is already installed and you can simply activate the add-on from the WordPress Plugins page, or install the Pro version update under the WordPress Dashboard > Updates page (as you would any other plugin update).

  4. After clicking the Plugin Details and Install link, click the Install Now button in the overlay window.
  5. Click the Activate Plugin button when WordPress is done installing the plugin.
  6. You can find the WPSSO JSON settings under the Schema Markup sub-menu.
