Secure authentication
The app is installed from the **Integrations **menu inside Zuddl and authenticates with the REST endpoint, Client ID, and Client Secret which is accessible from Admin › Web Services / LaunchPoint. Using OAuth instead of static keys means tokens inherit Marketo’s role permissions and can be revoked with a single click.One-time field mapping
During setup, you drop Zuddl fields onto Marketo counterparts in a visual map—First Name tofirstName, Ticket Tier to a custom pick list, Dietary Restriction to a text field—and set an update policy (overwrite, only-if-blank, or never). Mapping one-time prevents post-event VLOOKUPs, keeps data types intact for smart lists, and lets marketing automate segmentation immediately. If you surface a new UTM field later, drag it onto a Marketo property, and the next registrant carries it through automatically.
