Event hosts have the ability to submit a paid event registration on behalf of their guests, without entering credit card details and processing real payments. Here's how:
Step 1: Log into your RSVPify account
You must be logged into your RSVPify account to submit courtesy event registrations. If you are not logged into your account, the system will not recognize you as the event host.
Step 2: Go to your event's URL
Click on the 'View Event' button in the upper part of your screen, next to the action menu to go to your event's URL.
Step 3: Complete the registration with your guest details
On the last step, you will be asked if you want to charge a credit card, or process a courtesy registration. Select courtesy registration and click Continue.
The courtesy registration will be submitted and your guest will show as attending in your Dashboard > Overview.
