Please note: This feature is recommended for advanced users. It is meant to be used when you already have the contact's details and you simply want to speed up the registration process so that the contact does not need to re-enter their details. It is meant to be used in conjunction with 3rd party CRMs, email platforms, or API integrations.

One-click registration links should not be used to "scrape" contacts from websites and auto-enroll them into your events or spam leads that have not consented to being contacted. If your account is found to be in violation of the above policy, it will be subject for immediate termination. If you have any questions about whether your usage of one-click registration links is following our guidelines, please contact our support team.

WebinarKit supports one-click registration links for your events including automated and live webinars, as well as webinar series.

Essentially, one-click registration links allow you to append a registrant's information to the link so that all a person needs to do is click the link and they will get registered for your event.

A standard use-case for this is if you have a list of contacts in your CRM/email platform and you want them to register for an upcoming event: You can use one-click registration links to send out an email to those contacts with their email address appended to your one-click registration link. Then when that contact receives your email, all they need to do is click the link and they will automatically be signed up for your event, with the exact session time you want and all of their details prefilled.

Follow the steps below to properly set up your one-click registration links.

Get the one-click registration link for your event

First go to your webinars dashboard. Click the "Get links" option for the event you want. From the pop-up, click "Embed forms & links". From the dropdown, click "One-click registration links".

On the next pop-up that appears, select the date/time schedule that you want the one-click registration link to enroll registrants in. You can select any schedule you've added in your webinar settings. That means you can select "specific" session date/times, "ongoing" session dates/times (Example: The next session occurring on Friday at 3 PM), and just-in-time sessions. Instant watch sessions are also supported: Simply enable instant watch sessions in your webinar settings and the one-click registration link will override whatever date option is appended to the link.

After selecting the schedule you want your one-click registration link to use, copy the link.

Add registrant details to your one-click registration link

Now that you have your link, you'll need to append the registrant details to it before using it. Below is a simple example where we simply append an email address to the end of the link. This will create a registration for the event using the email appended to the link:

Notice in particular the "&". When setting up your one-click registration links, you'll need to replace "" with the contact's email address. Let's use a CRM/email platform as an example of how this would work in practice.

One-click registration links support the following fields appended to the URL:


Customizing your one-click registration link with your CRM or email platform

Say you're setting up an email broadcast inviting your email list to register for your upcoming event. In your email, you would use the CRM/email platform's personalization/merge features to append the contact's email address to your one-click registration link. Below you'll see a screenshot example of what this looks like in the email platform ConvertKit:

Notice how the "{{ subscriber.email_address }}" is used. This will be replaced by the contact's actual email address when that contact receives the email which is how WebinarKit will fill in the registrant's details for the event. Please note, every email platform/CRM is different so you'll need to replace the "{{ subscriber.email_address }}" with whatever your platform uses for personalization. Also, please note, it is best to URL encode the data appended to the one-click registration link. Many CRMs/email platforms support this as well so please consult their documentation on how to do this.

Some more examples:

A one-click registration link that creates a registrant with Joe Schmo as the name, as the email, and some custom field data:

A one-click registration link that creates a registrant with contact data dynamically passed in via a CRM/email platform:{!email}&first_name={!name}

Examples of personalization on popular CRM/email platforms:

Active Campaign

first_name={!name} or firstname={!firstname}


first_name={{ subscriber.first_name }}
email={{ subscriber.email_address }}

first_name=[[name]] or firstname=[[firstname]]
