Personalized links using [URL parameters](https://help.staticso2.com/scheduleonce/sharing-publishing/personalized-links/url-parameters-syntax-and-processing-rules "ScheduleOnce URL parameters and processing rules") are [Booking page](https://help.staticso2.com/scheduleonce/event-types-booking-pages/booking-pages/introduction-to-booking-pages "Introduction to Booking pages") links that contain Customer information and [Booking form](https://help.staticso2.com/scheduleonce/customization-branding/booking-forms-editor/introduction-to-booking-forms-editor "Introduction to the Booking forms editor") data. With **Personalized links (URL parameters)**, prospects and Customers click on your Booking page link and pick a time, without having to provide any information that is already known to you.

The Booking form can either be [prepopulated with their details](https://help.staticso2.com/scheduleonce/event-types-booking-pages/booking-forms-redirect/prepopulated-booking-forms "Prepopulated Booking forms") or skipped altogether. You can also add [source tracking](https://help.staticso2.com/scheduleonce/managing-bookings/analytics/using-oncehub-with-utm-tracking "Using ScheduleOnce with source tracking (UTM tags)") tags to personalized Booking page links, letting you analyze where your bookings come from.

Note

When you use Personalized links with Booking pages that are [not associated with any Event types](https://help.staticso2.com/scheduleonce/event-types-booking-pages/booking-pages/adding-event-types-to-booking-pages "Adding Event types to Booking pages"), it is highly recommended you provide the **Subject** field of your Booking form.

You can do this by going to **Booking pages** on the left **→** Relevant Booking page**→** **Booking form and redirect**. In the **Meeting subject** section, select **Meeting subject is set by the *Owner* (you)**. You can then enter a meeting subject for your specific business case.

## Adding your own URL parameters

[Section titled “Adding your own URL parameters”](#adding-your-own-url-parameters)

If you need to replace the **ADD\_DYNAMIC\_FIELD** placeholders (Figure 4) with your own parameters, you can copy the link to a notepad. [Learn more about supported OnceHub URL parameters](https://help.staticso2.com/scheduleonce/sharing-publishing/personalized-links/url-parameters-syntax-and-processing-rules "OnceHub URL parameters and processing rules")

Merged values must be properly encoded in order to be passed in the URL. Some characters like at (@), period (.), dash (-) and underscore (\_) are OK, but all URL invalid characters like plus (+) or space ( ) must be URL encoded.

For example, if you use [MailChimp](https://help.staticso2.com/scheduleonce/sharing-publishing/personalized-links/personalized-links-in-email-marketing-apps "Using Personalized links (URL parameters) in email marketing apps"), the link might look like this:

\*[https://go.oncehub.com/dana?name=\\\*|NAME|\\\*\&email=\\\*|EMAIL|\\](https://go.oncehub.com/dana?name=%5C*%7CNAME%7C%5C*\&email=%5C*%7CEMAIL%7C%5C)\*\*

In this example, the **\*|NAME|\*** and **\*|EMAIL|\*** fields are merge fields which are replaced with a single Customer name and email respectively during the email campaign, creating a personalized email for each lead in your list.
