There is no official in-app transfer option offered for Eventbrite tickets. We recommend that sellers save the PDF ticket documents that were delivered to them via email by Eventbrite. Then the seller can upload the PDF file of their tickets into the CashorTrade chat thread with their buyer. We also encourage the seller to email the PDF tickets to the buyer's confirmed email address so they have 2 different ways to access the ticket(s).
There may be an option to 'edit order information' to put the ticket in another person's name and email address, but this does not change the barcode of the ticket, only sends the ticket to the new email address that is provided. As always, if there are issues retrieving the original tickets from Eventbrite please contact Eventbrite's support team for further assistance.
