Hey Marcie,
Thanks for reaching out.
Eventbrite is a total event-management and ticketing platform; it is not a payment gateway.
So there are two options here.
Option 1: Selling tickets through Eventbrite.com
If you would like to sell tickets through Eventbrite.com, and to be able to import those events into your WordPress site so they show up on your WordPress site, then Event Tickets, Event Tickets Plus, and WooCommerce will not do this and thus are not necessary.
You would just need these two plugins:
• The Events Calendar (free)
• Eventbrite Tickets (premium): https://theeventscalendar.com/product/wordpress-eventbrite-tickets/
Option 2: Selling tickets on your own WordPress site
If you would like to sell tickets on your site directly, then you cannot use Eventbrite to sell those same tickets. It’s unfortunately one or the other. 🙁 If you want to keep the ticket sales process entirely on your site, then do not use Eventbrite.com for anything. Instead, you would use these plugins:
• The Events Calendar (free)
• Event Tickets (free)
• Event Tickets Plus (premium)
• WooCommerce (free)
When it comes to the available payment gateways for WooCommerce, you could use any of the official WooCommerce gateways which are listed here.
I hope this information helps!
