Donations and Ticket Purchases Explained
If they only make a donation without availing a ticket, they won't be able to enter the event as a donation will not issue them a ticket. They will still need to get a ticket to enter your event.
To make sure that they can enter the event, you can give them a ticket by registering them through your Add Attendees tab.
Add a Donate Option While Buying Tickets
When creating a ticket type, you'll see options to create a Paid Ticket, Free Ticket or Donation. A Donation is not a ticket, but when you pic this option, it adds a donation option in the registration process.
When you add the donation option, it will appear at the bottom of the ticket selection when they register for your event, with 4 suggested amount and a field to enter a different amount than the suggested ones.
Change the Donation Suggested Amounts
To change the suggested amounts:
Go to Settings > General Settings
Enable the Donation Page toggle
Go to Donations > Settings
Update the amounts
Go back to Settings > General Settings and turn off the toggle if you don't wan't the Donation tab to appear on your landing page
Email Confirmation for Donations Only
The default email template looks like it's an email for ticket buyers, we suggest creating a custom email through the advanced templated builder for those who are donating only to avoid confusion.
Note: Make sure to move your donation email template below the default template, so that when someone buys a ticket and donates, they will receive the default template.
