Can I enter the purchase terms & conditions without a separate URL?

If you do not have a separate URL, and do not want to create one for your terms of purchase, there is an alternative:

Open your Draft Event:

1. From the top menu, click on Events > My events. You will see your list of events.
2. From the three tabs, click on the Drafts tab. 
3. From the My events list, click on the Name of the event you would like to update.

Open the Event Settings:

1. On the top-right corner of the My events bar, click the Event Settings cog icon. The Event Settings window will open. 

Go to the Booking settings tab:

1. From the left-hand menu, click on the Booking settings tab.
2.  From across the top, click on the Collect Attendee Information tab.
3. Click the Add Field button.
4. In the Field settings, in the Field name box, enter your terms & conditions statement.
5. Click the Save button.

Note: To edit an already published event, you will need to unpublish it first. (For instructions, see How can I change a published event? Unpublishing an Event.)
