Which token would a marketer use to include a unique access URL in a webinar confirmation email?

The {{member.webinar url}} is a system token used within Marketo Engage event programs that are integrated with a webinar service provider (e.g., GoToWebinar, ON24, Webex). When a person registers for the webinar, the integrated service generates a unique join URL for that specific individual. This URL is then synchronized back to Marketo and stored in the program member's record. Using the {{member.webinar url}} token in a confirmation email ensures that each registrant receives their personal, unique link to access the webinar.

A. {{my.member URL}}: This is not a valid system token. {{my.}} tokens are used to reference local, custom variables defined at the program or folder level, not system-generated data like a unique webinar URL.
C. {{lead.webinar url}}: {{lead.}} tokens pull data from a field on the person's global record. Storing a webinar URL here is impractical as it would be overwritten with each new webinar registration, and it cannot manage unique URLs for multiple events simultaneously.

1. Adobe Experience League Documentation, "Tokens for a Program": This document lists available system tokens. Under the "Member Tokens" section, it defines {{member.webinar url}} as "The unique URL for a person to view the webinar. This is provided by the webinar partner." This confirms it is the correct token for this specific use case.

2. Adobe Experience League Documentation, "Add a Webinar Provider to an Event": This guide explains the integration process. It notes that after a successful registration, the webinar provider passes information back to Marketo, including the unique confirmation URL for each member, which is then accessible via the {{member.webinar url}} token for use in communications like confirmation emails.
