You might have a special agreement with a buyer about a custom booking, that you want to send them a link to make, for example if a school has arranged to book for a certain day, or if you have a discounted block of tickets for a sponsor.
To directly share a payment link for a specified number of tickets:
Head to your event and open 'Edit event and tickets'.
Scroll down to 'Create ticket types'.
Add a new bundle.
Add the price you want your customer to pay.
Add the amount of ticket types reserved for your customer.
Open the advanced settings for your bundle.
Under 'Status', select 'Access code required'.
Enter your case sensitive access code (for example REVEAL)
Get your event link, and add: ?a=REVEAL to the end of it., where "REVEAL" is your chosen access code.
For example, if my event link was 'https://buytickets.at/demowindfarm/1397105' and my access code was 'REVEAL', then my secret link would be: 'https://buytickets.at/demowindfarm/1397105?a=REVEAL'
Share this link with your buyer.
