Hello,

Thank you for reaching out to us.

Starting from Amelia 7.4.2, users can pre-select a list of entity IDs separated by commas, which will be automatically pre-filled on the form. The following list of URL parameters can be added to achieve this:

• ameliaEventId: The ID of the event that will pre-filter Event-related shortcodes;
• ameliaEventTag: A specific tag added to an event that will pre-filter Event-related shortcodes;
• ameliaServiceId: The ID of the service that will pre-filter appointment-booking shortcodes;
• ameliaEmployeeId: The ID of a specific employee that will pre-filter appointment-booking shortcodes;
• ameliaCategoryId: The ID of a specific category that will pre-filter appointment-booking shortcodes;
• ameliaLocationId: The ID of a specific location that will pre-filter appointment-booking shortcodes (can only be used for Service-related booking forms, not Event-related booking forms);
• ameliaEventPopup: Enter the event ID of the event to be opened on page load.

Event URL:

• https://yourbookingwebsite.com/events/?ameliaEventId=123&ameliaEventPopup=123
• This URL would automatically open the page where Event ID “123” is located and would display it in a popup.

Booking Form URL:

• https://yourbookingwebsite.com/booking/?ameliaServiceId=5&ameliaEmployeeId=1
• This URL would pre-select Service ID 5 and Employee ID 1 in the booking form.

Please note that these are examples and not live websites. They demonstrate how a URL with predefined parameters would function.
