The external ID field lets you identify users in the Webex Events Platform with your preferred unique identifier from a third-party or proprietary system. Using this field, you can identify users with their external ID throughout the Webex Events Platform.

About External IDs

The External ID lets you easily "match" users across systems. External IDs also let you easily export from our system and import into the system that uses that ID — and vice versa!

Using External IDs

There are two ways to add External IDs to an attendee profile. You can update the field in bulk using the Attendee import template or individually in a user's Event App, Onsite, or Registration attendee profile.

To view and edit a single user's external ID field, go to the Users & Groups tab ('Attendees' in Onsite or Registration) and click a user to view their profile. Click the Settings (⚙️) icon, click Edit, and then scroll down and expand the 'Advanced Settings' section. This reveals the 'External ID' field. Don't forget to click Save Changes after editing the ID!

When you edit a user's external ID in one Webex Events product, their profile in other linked products automatically updates as well. For example, if you edit the external ID in a Webex Events Registration that's linked to an Event App, the attendee profile in the event updates too.

⭐️ Keep in mind, the maximum number of alphanumeric characters for the External ID field is 255.

⚠️ Caution, you can only edit the External ID field once. After you save a change, the field is locked.

Pass External IDs to a URL

If Lead Retrieval is active for your event and you activate the Pass Data to URL option for an External Link, the passed data includes External IDs. This is a great option if you're linking to a survey and want to reference each response by external ID.

External IDs and Lead Retrieval

When used with Lead Retrieval, you can use the external ID to generate attendee QR codes.

Enable External ID as QR Code

Lead Retrieval will now use external IDs to generate the attendee QR codes. If an attendee doesn't have an associated external ID, the attendee is assigned a Webex Events QR Code.

External IDs and Onsite

If you're using Onsite as a standalone product without purchasing Registration or an Event App, you must import attendees into your Onsite event. When you import an attendee file, the values you include in the external ID column automatically generate QR codes. These QR codes can then be printed on badges!
