[Creation & Setup](https://kb.bigmarker.com/knowledge/webinars-and-series?hsLang=en#creation-setup) # Enabling One Click Registration ## Set up One Click Registration for your events to streamline the registration for attendees whose information is known prior Using the classic admin? [Click here](https://kb.bigmarker.com/knowledge/enabling-one-click-registration#session_admin) to learn where you can find the one-click registration setting. One-click registration allows you to send a unique URL to your audience that will register them immediately when they click on it. This means that your audience faces the smallest barrier to entry when it comes to registering for your webinar, series or event. One-click registration can be found in **Basic Setup \> Registration fields**. Visit the settings tab in this section to find the setting. ![](https://kb.bigmarker.com/hs-fs/hubfs/image-png-Jan-21-2026-10-09-59-0349-PM.png?width=600&height=194&name=image-png-Jan-21-2026-10-09-59-0349-PM.png) Once enabled, you will add parameters to the URL of the corresponding landing page to fill in your registration information. If you are sending invitations through BigMarker, email addresses will be added automatically to the URL that the recipients click on. If you are sending invitations through your own email service, the URLs will need to get personalized and updated on that platform. One-click registration emails will work with webinars, series and events. However this setting is not compatible with the [**itinerary series**](https://kb.bigmarker.com/knowledge/itinerary-landing-page-a-new-landing-page-template?hsLang=en) One-click URLs work using [pre-filled registration fields](https://kb.bigmarker.com/knowledge/how-can-i-add-pre-filled-values-to-my-registration-form?hsLang=en) in the URL as parameters: ?first\_name={value}&last\_name={value}&email={value} A one-click url might look something like this: `https://www.bigmarker.com/Channel-name/webinar-title?email=yourname@website.com&first_name=John&last_name=Doe` For users that have already registered on BigMarker, you can also just only use the BMID for the way to identify the user: `https://www.bigmarker.com/Channel-name/webinar-title?bmid=xyz` To add Custom Registration Field responses to one-click registration links, add a URL parameter using the Custom Registration Field Field ID as the name, which can be seen when editing a Custom Registration Field, e.g. `https://www.bigmarker.com/Channel-name/webinar-title?email=yourname@website.com&first_name=John&last_name=Doe&20542fe4f664=Manufacturing` ![](https://kb.bigmarker.com/hs-fs/hubfs/image-png-Sep-23-2024-03-55-25-3824-PM.png?width=670&height=304&name=image-png-Sep-23-2024-03-55-25-3824-PM.png) ###  One-click registration in the classic admin To enable one-click registration visit the **edit tab** of the [webinar dashboard](https://kb.bigmarker.com/knowledge/the-manage-webinar-dashboard?hsLang=en) and look for the setting **One-click Registration **under the advanced settings ![](https://kb.bigmarker.com/hs-fs/hubfs/image-png-Nov-25-2025-04-50-45-5545-PM.png?width=600&height=222&name=image-png-Nov-25-2025-04-50-45-5545-PM.png) -
