The Self-Book scheduler allows visitors to your calendar to book events with you based on your availability. You can either set up pre-defined appointments that visitors can book, or they can choose to book any slot in your calendar that hasn't been blocked.
When visitors book an event, you can choose what time increments visitors book their appointments and require that they select a booking duration. Follow the steps in the image below:
The next screen is where you customize the settings for your Self-Book scheduler. In the "Event duration" field, you can type in your appointment intervals in minutes (ex. 15, 30, 45, 60). Each time interval is separated by a comma. When you save your changes, your event durations will show up in a drop-down menu in your Self-Book scheduler. See the image below:
When a visitor selects a booking duration, the available bookings that are listed will change to reflect that booking duration automatically.
