A Channel-specific link for your Online Purchase Flow.
You may want to create one for your mailing list, priority bookers or if you want to have a booking flow for a certain Payment Method.
Each Channel will have its own unique URL which you can send to customers to make purchases through that Channel. You'll just need to create a Channel and Purchase Flow before setting one up.
You can also build your own URL link, where you can link to a specific Event, Performance or Discount.
