To integrate with third party apps, you need to be on the Business or Enterprise plan. Then you will have access to the Integrations features as shown here:
EventCreate offers pre-built touch integrations for attendees (so you can share attendee data with another platform, for instance), registration and orders (e.g. so you can track and manage your ticket revenue anywhere). Some of our most popular integrations include: MailChimp, Salesforce, and Zapier.
For instance, if you manage your event newsletter program using Mailchimp, you might want to connect your attendee name and email address with a Mailchimp account. That way every attendee is automatically subscribed to your mailing list. Or, you may choose to manage all of your customers in Salesforce, so when you get an attendee, you can choose to add them automatically and easily to your favorite CRM. Lastly, if you’re selling tickets, you can decide to track your orders in Freshbooks, so when you get a new purchase, it’s automatically added to your revenue tracking software.
