Product Type: Advertising

Integration Type: Starter Kit & ID Sync

Capabilities

• Captures the Perion user ID (perion_utid) through a first-party identity request.
• Optionally generates a session ID (perion_sessionID) using MetaRouter’s built-in session sync feature.
• Adds identifiers to server-side event payloads for accurate user attribution.
• Stores both identifiers as first-party cookies with configurable lifetimes.

Considerations

• Your domain must be allowlisted by Perion for the sync to function. Contact your Perion representative to complete the necessary CORS setup.
• If you choose to provide your own session ID, you must update the starter kit mapping to reference your custom value.
• Session sync must be explicitly enabled in the MetaRouter UI to generate and persist perion_sessionID.

Limitations

• The sync will fail if your domain has not been added to Perion’s allowed CORS origins.

Sync Details

• IDs:
  • perion_utid – A unique identifier returned by Perion to track and attribute users for conversion reporting.
  • perion_sessionID – A session-level UUID generated by MetaRouter (if enabled) to group events from the same session.
• Description:
  • A first-party identity sync is triggered to retrieve the perion_utid.
  • The perion_utid is stored and automatically included in all server-side events.
  • If the Use Session Sync setting is enabled, MetaRouter generates a perion_sessionID to group events within a session window.
  • Your domain must be added to Perion’s CORS allowlist in order for the sync to succeed.
  • If the sync fails, a temporary failure marker (_perion_utid_failure) is stored and retried after 1 day.
  • Identifier lifetimes (e.g., 30 days for perion_utid, 30 minutes for perion_sessionID) are configurable in the MetaRouter UI.
• Response Example: { "utid": "ez3oezmyay3" }
• Server-side Event Payload: Upon completion of all vendor's sync, the server-side events will incorporate all resolved identifiers as described above. The following object will be appended to the context.providers property within the event's JSON payload.

  {
     "perion": {
       "utid": "foo123",
       "sessionCount": 1, // Not used
       "sessionID": "1746702483972",
       "sessionTimeToLiveInMinutes": 30 // Informative and not used
     }
  }

• Cookie Name:
  • Cookie: _perion_utid, _perion_sessionID, _perion_utid_failure
  • IndexedDB: [your storage prefix]_perion_utid, [your storage prefix]_perion_sessionID, [your storage prefix]_perion_utid_failure

Sync Setup Guide

1. Gather Credentials

• No credentials are needed; however, your domain must be allowlisted by Perion for the sync to function. Contact your Perion representative to complete the necessary CORS setup.

2. Add a Perion Sync in MetaRouter

To gather the perion_utid and optionally the perion_sessionID, you must add a Perion sync.

1. From the Pipelines page, find the pipeline associated with the web property you’d like to add a sync to. Hover over the three dot dropdown and select “Build AJS File.”
2. In the Identity Syncs section, select the Perion sync.
3. Fill out the following fields:
   1. Use Session Sync – Enable this if you want MetaRouter to generate and store a perion_sessionID.
   2. Session Lifetime (in minutes) – (Optional) Defines how long the generated session ID remains valid. Defaults to 30 minutes.
   3. Cookie Lifetime (in days) – Defines how long the Perion user ID remains valid. Defaults to 30 days.
   4. API Timeout (in milliseconds) – (Optional) Sets the max wait time for a response from Perion. Defaults to 300ms.
4. Scroll down and click the Save and Build File button.
5. Deploy your AJS file to propagate changes to your web property.
