SharedID Edge

Migrate from the WordPress or Drupal plugin ​

The plugins and SharedID Edge implement the same contract, so switching is a configuration change:

  1. Deploy SharedID Edge and verify it (see Pick your platform). Keep the plugin installed for now.
  2. In your Prebid.js configuration, change pixelUrl from /wp-json/pubcid/v1/extend/ (WordPress) or /pubcid (Drupal) to /_sid/sync.
  3. Use the same cookie name as the plugin (its default is _pubcid, the same as here), and the same domain as Prebid.js: SID_COOKIE_DOMAIN is required, normally your registrable domain (example.com). If the plugin's "Cookie Domain" was empty, its cookies were host-only while Prebid.js wrote its own on the registrable domain; set the registrable domain here to end that split. The worker deletes the plugin's old host-only _pubcid the first time a browser sends it next to the domain cookie, keeping the older value.
  4. Once the new pixelUrl is live, uninstall the plugin.

Existing visitors keep their IDs: the worker adopts the cookie the plugin set. Two differences:

  • First visits: the plugins only re-set a cookie that already exists, so a new visitor's first sync sets nothing unless you configured a "Generate Function". SharedID Edge adopts the ID Prebid.js sends with the first sync, so new visitors get a server-set cookie straight away.
  • Consent: the plugins call a PHP "Consent Function". SharedID Edge checks consent itself; see Consent and opt-out.
