In the Campaign you are creating, you can add the Appointment feature which will allow your users to book an appointment using the Campaign.
Creating an Appointment calendar is very easy. While creating a campaign, you can create an Appointment using the Call to Action feature. Under Call to Action, you will see three options, Polls, Appointment, and Action Buttons. Just click on the Appointment and a new box will appear. See the image below.
Once you click on the Appointment, you will see a new box that contains various options to set up.
Enter Title: Here you have to type the name of your appointment. You can enter any name of your choice.
Close Date: This will be the date until which your Appointment will be active. After this date, it will be disabled automatically.
Agenda: This description will be visible to the users who will be booking your appointment. You can write anything catchy here to attract clients to book appointments.
After completing all the fields and enabling the Appointment, click on the Next button. Now, you need to add more details like your Time Zone, Time Duration - Maximum time of your one appointment, and most important your Availability Time - like on which days you want the appointment and also the time slots.
Once you have added all the necessary details, click on the Save Changes button and your appointment will be created.
