When you add an External Link in the Webex Events platform, the 'Pass Data to URL' checkbox is usually right below the link field. Its job is to simplify attendee interactions on external sites they access by clicking an external link.
What does 'Pass Data to URL' do?
Simply put, 'Pass Data to URL' lets you send attendee and event information from the Event App to a website when attendees click the website's URL in your Event App. Data passed from the Event App can pre-fill forms such as surveys, sign-up forms, calendar apps, and more. This means people don't have to re-enter information they may have already supplied in your Event App.
How to pass data
Passing data is as simple as checking the 'Pass Data to URL' checkbox after entering an external link into any of the following features:
Live Stream feature (Custom Tab)
Sessions (External Links, Custom Tab)
Sponsor/Exhibitor profiles (Attendee Calls to Action, External Links)
Speaker profiles (Attendee Calls to Action, External Links)
Custom List items (Attendee Calls to Action, External Links)
Banners (when the Event App is set to the Banner layout)
Add the link and check the box
In any of the above Event App features, simply enter the URL and check the Pass Data to URL box. When attendees click the external link you provided, Webex Events passes the data listed later in this article to the URL clicked.
Prepare the external site
For passing data to work, the website must accept the data in the correct format. While this often happens automatically, some configuration on the external website may be necessary to properly map the data.
For example, if you pass data to Typeform, you have to add the Webex Events data fields as 'Hidden Fields' before passed data can auto-fill surveys. Learn more about passing data to Typeform in our Typeform and Webex Events article.
It's up to you to identify, implement, and test any changes required for the external site to use Webex Events data. As you'll notice in the next section of this article, Webex Events field labels follow a very simple, common convention, so there's a good chance a website already uses these formats. 👍
Data fields we pass
The fields that Webex Events passes depend on the feature or item the data passes from. Here's a breakdown:
Webex Events always sends the following data fields:

When the Webex Events platform detects a Slido URL, only the following data points are sent. Slido also automatically adjusts its display language based on the user's language selection in the Event App!
user_name (full name)
Here's an example of how data passes in the URL to Slido. The format of the data passed from Webex Events won't change, regardless of the website it's sent to.

Fun fact: Slido doesn't require any configuration to accept data passed from Webex Events! Read Slido & Webex Events for more on integrating Slido with your Webex Events App.
