Customization overview

IO gives you full control over how your event looks to attendees — from the registration page to confirmation emails, digital passes, and beyond.

Levels of customization

There are several levels of customization available, depending on how much control you need:

1. Basic customization — set your brand colors and banner image, and add a logo to your receipts using the built-in settings. Brand the Apple Wallet and Google Wallet digital passes your attendees receive. No coding required.
2. Template customization — modify the HTML templates for registration pages, emails, and other attendee-facing content using IO's template editor.
3. Fully custom layouts — build completely bespoke registration experiences using custom layouts with full HTML/CSS control.

Where to start

If you're new to customization, start with basic customization to set up your logo and colors. Once you're comfortable, explore template customization for more control, or jump straight to fully custom layouts if you need complete creative freedom.
